2007 Nissan Altima motor mounts are new went I put the car on drive and put the ac on the motor vibrates a lot went I turn off the ac it's still there but not as much as with the ac on another problem I'm having is went I acelarate my car like I step on it out no we're I heard a winning loud sound as I'm accelerating the car once it reaches let's say 50 mph it goes away
My car has 101000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. It is possible that you have a vacuum leak or perhaps the transmission mounts are loose, as usually these symptoms are common with worn out motor mounts. When the AC is activated, it does create additional drag on the motor, which can make a small vibration even worse. It’s probably a good idea to have a professional mechanic come to your location and try and replicate the symptoms you are describing by completing a car is shaking or vibrating inspection.
How to Identify and Fix Common car Problems ?

The first obvious sign of bad motor mounts is; excessive engine vibration. Motor mounts are made to hold your engine in place and absorb vibration. If your engine is shaking in place, it`s probably a sign of bad motor mounts.
Common reasons for this to happen:
Loose connections at the positive and negative battery terminals. Very dirty or clogged air filters can also cause your engine to underperform. Loose timing belts are another likely cause. A mechanic will check these and replace them if they appear loose and worn.
Engine Shudder
Engine problems typically mean it isn`t getting enough fuel, air or it isn`t properly charging. If the issue is at startup, you might check your spark plugs, air filters or suspect the starter is going. If your vehicle doesn`t seem to have enough juice, your battery or alternator may be on the fritz.
Engine mounts are made of a hard rubber material which allows them to absorb these vibrations. When a motor mount is damaged or broken, not only will you feel excess vibration in the car, other parts in the engine can get misaligned and ultimately break since the engine is not in its precise location.
As your motor mounts wear out, they can cause vibrations and engine shaking that can cause your entire vehicle to experience a decrease in ride quality.
Torque settings are available for these fasteners. The mounts will settle slightly after installation.
Worn or dirty spark plugs can cause a petrol car`s engine to misfire in one or more cylinders, which can cause vibrations when the car is idling or at running speeds. The easiest solution is to replace your spark plugs and check the related wiring. Engine vibrations can also be due to the air and fuel systems.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
A: A four-cylinder engine will typically have a slight vibration when idling. This is inherent in the design and may in fact be normal.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
The most common symptom of engine or transmission mount failure is a shudder upon acceleration. It is a vibration experienced by the driver. If the car is a stick shift, you will see the handle vibrating significantly.
The most likely cause of the shuddering most often happens in the vicinity of your car`s rims and tires. They plant your car to the road, and if anything is broken, will feel it. On a serious note, it may be a broken transmission mount or a broken caliper.
In extreme cases, broken motor mounts can lead to engine damage. If your engine is given enough room to knock around, it can hit other components, causing damage to itself and other essential parts.
A failing motor mount can lead to serious engine damage and will also greatly impact the performance of the vehicle. It is very unsafe to drive with a broken motor mount. If you feel a lot of vibration in the vehicle while you are driving, there`s a good chance it`s the motor mount.
` Over time, the noise then starts to become an unmistakeable `clank` or `bang` before resulting in the failure of the mount or even worse – the engine. In summary, inferior or damaged engine mounts can cause vibration and damage, whilst replacing your engine mounts can eradicate all the above issues.

Yes, performance. Although the foremost job of drivetrain mounts is to dampen the noise and vibration from the mechanicals of the car to the cabin, it can also affect power delivery, shifting, and even handling.
While relatively harder, there are some benefits to choosing polyurethane motor mounts over the factory-installed rubber. These are a good option if you are looking to do some performance upgrades to your car that will increase its power, as they are more rigid.

My car vibrates when I’m waiting at the light . It drives fine . And it vibrates more when I turn on the ac? Can itvtve motor moun
ANSWER : There are two principal possibilities: faulty motor/transaxle mounts, or an engine operating or mechanical condition including the possibility of a faulty harmonic balancer. To obtain a conclusive diagnostic, please simply request an engine vibration diagnostic and a certified Mechanic, dispatched by YourMechanic right to your location, will get this resolved. If you do need new motor/transaxle mounts, genuine OEM Nissan mounts are recommended in order to maximize the chances of resolving the problem. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
As I’m driving, all my lights inside/out of the car turn off and the car still stays on. But when I turn the car off it won’t turn over
ANSWER : Hello there. The charging system on the car may not be charging the battery as you drive and the systems that keep the engine running are priority so the engine will stay running until the voltage drops below about 9 volts but the lighting and some other accessories may cut off above this voltage first. You should have the charging system tested to see if the alternator needs to be replaced.

ANSWER : Hi There,
It sounds like you may have a dirty or faulty mass air flow sensor. The problem this can cause may also be compounded when the engine is cold due to the change in air density in cooler weather. The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the motor. This sensor relays information about fuel and air temperature, air speed entering the motor and many other things to the ECM which uses this to make adjustments to fuel supply to the motor. A dirty or faulty sensor can cause an imbalanced air/fuel load to be supplied to the motor which results in an over fueling or under fueling situation depending on the conditions. This type of inconsistent fuel supply to the motor may cause a hesitation, loss of power, a jerking reaction, potentially a bit of black exhaust smoke and typically a strong smell of fuel when this sensor is malfunctioning. I would suggest having a professional from Your Mechanic come to your home to diagnose and inspect your vehicle.

Car died while driving so I replaced the alternator and battery and car won’t attempt to turn over. What else could it be?
ANSWER : The initial failure was likely caused by a sudden fuel system (e.g., failed fuel pump) or electrical (including ignition) faiure. Prior to performing diagnostics be sure you have a fully charged battery that passes a load test. Then, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the starter motor is not functioning, check for power to the starter motor when the key is held in the "start" position. If there a large voltage drop at the starter motor or no power at all, you may have a faulty ignition switch but you do have to check out the entire starter circuit, which includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. On the other hand, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. If you desire that a certified mechanic resolve this, please simply request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you.

When I stop my car it starts to turn off. When I run my car for a bit and turn it off, it won’t turn back on when I twist the key.
ANSWER : Hello.
If the car doesn’t crank then there is likely an issue with the starting or electrical system. If the issue began after you installed the new battery then the first thing I would do is check the battery to make sure that is holding a charge and providing adequate power. Even if the battery is new it may be possible that it is faulty.
It may also be possible that there is an issue with the ignition switch or even the starter. If there is an issue with the ignition switch then it may cut off power to the starter, resulting in a no crank condition. The same can happen if the starter or starter solenoid are bad. I would also look at the fuses and relays to make sure that none of them are burned out or bad, as there are a few that can prevent the vehicle from starting. As no-start conditions can sometimes be difficult to diagnose, I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose the cause of the no start condition.
I have a 09 Nissan Altima 2.5 Base Sedan has about 85k miles. After driving the car for about 15-20 on really hot days it starts m
ANSWER : Hi there. In some cases, a problem with the EVAP system; either an EVAP canister or purge solenoid can cause this type of symptom on extremely hot days. Another possibility is that you have an obstruction of fuel somewhere in the fuel system, like the throttle body, fuel injectors or the fuel filter. This could be difficult to diagnose for a professional mechanic as replicating the symptom is going to be difficult; unless it’s a hot day as you indicated. It would be a good idea to have a professional mechanic come to your location to complete a car is making a noise inspection, to isolate the source of that noise – as that sounds as if it’s a loose drive belt or perhaps something internal.
