Car won’t start, and rear windshield wipers don’t work

My car will not start and it appears to be due to an electrical issue. We replaced the battery 2 weeks ago (with a brand new battery). We had no problems at all, until today, and then the car would not start. It did not cough, struggle or splutter; it just made a clicking sound and would not start. I am going to take it to the mechanic, but would like to know what it is being caused by. Also, I should note that our rear windshield wipers don't work at all, and this too seems to be caused by an electrical issue. Any ideas?
Experienced mechanics share their insights in answering this question :
Most likely, these are two separate issues. A vehicle that doesn’t crank or start indicates a problem in the starting/charging system.

It may be that the battery connections didn’t get tightened down properly at the time of replacement. The cables themselves could also be in need of repair, or the starter motor could have failed. The problem could also be in the starting system circuit or there could be an engine mechanical problem, although not likely.

The inoperative wiper could be the result of anything from a blown fuse to a problem with the wiring.

I suggest you double check the battery connections. If everything is good and tight, call a professional for a diagnostic inspection of your no start condition and inoperative wiper, and recommend the best path to repair. The team at YourMechanic is an excellent option since we make house calls.

There are two moving parts in the wiper, that is the wiper motor and the wiper transmission. If you hear a clicking sound it could mean that the motor is trying to move a locked transmission or jammed motor gear. The gear could have been stripped off its teeth and is causing a clicking sound while rotating.
Wiper blade chatter is common in many cars even with new wiper blades. The first thing to do is look at the windshield wiper blades themselves. Are they old, torn, stiff or dirty? If the wiper blades are more than one year old replace them—it will be money well spent.
There are a number of reasons why windscreen wipers stop working and these include: torn wipers, broken controls, a blown fuse, faults with the motor, damaged arms, snow or ice covering, loose pivot nuts and a break in the wires.
Before the wiper motor goes bad, you will probably experience a blown wiper fuse, which is intentional. The fuse is designed to be the circuits weak spot, which protects the wiper motor. Essentially, if your vehicle`s wiper motor is being overloaded, the fuse will blow to ensure the motor does not become damaged.
Clear Clogged Windshield Washer Nozzles

Clear the clogged windshield washer nozzle with a pin, then use compressed air to blow the debris backward through the hose. If you hear the pump going but don`t get fluid, you probably have clogged windshield washer nozzles.

Electrical Faults

These include broken or frayed wires, clogged or loose connectors, and bad relay or blown fuse. It could also be a faulty wiper switch or wiper motor control module. Every component of the wiper motor wiring system performs a specific role. When it goes bad, the motor will not receive power.

There`s an electric motor solely dedicated to powering your windshield wipers. As an electrical appliance, this motor can short out which will cause your wipers to not move at all. The fuse in your motor can also blow which will cause the same outcome.
Listen for the pump whirring and see if you can feel any vibration when the switch is activated. If you can`t, the pump is faulty; if you can, there`s likely a blockage or a leak from the reservoir. If the pump isn`t working, turn the power off and access the bottom of the washer reservoir.
The national cost for a windshield washer pump replacement in 2023 is between $63 and $224 with an average of $125.
Windshield wipers are powered by a small electric motor, usually mounted on the firewall or under the cowl (the area under the windshield`s base). The motor activates linkage that moves the wiper arms back and forth. On vehicles with a rear window wiper, a separate motor powers the one in the rear.
The windshield wiper module, or governor, controls the wiper motor operation. The module receives input from the wiper switch, and in some cases from various sensors as well. It is responsible for determining wiper speed and parking.
Integral body control module features include: Ensuring safety, testing, and control of crucial electrical loads, including lights, immobilizers, air conditioning systems, locking systems, and windscreen wipers.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.

The car crank but won’t start
ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.

Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.

At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.

Interior lights work but car won’t start and power locks won’t work 97 Honda passport
ANSWER : You possibly have a dead battery. Batteries that are "partly" dead can often still run lights, dash lights and so forth but will not have enough power to run the starter motor and start the car. The very first thing to do is be sure you have a fully, 100% charged battery that passes a load test. If the battery passes a load test be sure it is NOT a marginal pass in which case you should simply install a new battery to reduce diagnostic headaches. Batteries are a VERY important component in a car’s electrical system. Once you have a fully functioning, preferably new battery (fully charged before you leave the store), if the starting system still does not function, there are only a relatively limited number of causes. Broadly, either the starter motor/solenoid assembly is faulty or the electrical circuit supplying the motor has a fault. That circuit begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. Basically, the starter is either getting power or it isn’t. If the starter motor is getting power but it doesn’t work, the starter is condemned and replaced. Alternatively, if there is no power to the starter, then the starter circuit is traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. If you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you, including installing a new battery if required.

Car won’t start and no light on the dashboar. Lights, radio, wiper, a/c working. 1994 Honda Civic
ANSWER : Hi there, I would first check for blown fuse(s) and any relays for the ignition and coils. The "smoke came out of the steering wheel" is alarming! You may have a burned out ignition switch, or damaged wiring in the steering column. The "cranks, but doesn’t start" sounds like there is no power to the coil and plugs. I recommend a engine not starting inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
