If I turn the air ride off while it is inflated, will it stay inflated?

ANSWER : Hello. For most vehicles, the air suspension should stay inflated once the compressor is powered off or deactivated. In some cases, the release valve is also powered off when the compressor is powered off, allowing the system to stay inflated even if the compressor is not on. In some cases, you can remove the fuse for the compressor once the suspension has inflated, and it will stay on.

If the system does not stay inflated, then there is likely a leak in the system that needs to be addressed, or it is not a type of system that will hold air without a functioning compressor.

Keep in mind that even if the suspension does stay inflated, the compressor will need to be replaced in order to restore full functionality to the system. I would recommend having a professional technician, such as one from YourMechanic, come to your location to replace the compressor so that this can be addressed.

ANSWER : Hi there. Based on your question and input, it looks like your AC control switches are damaged, causing the vents to activate even if the switch is not activated. This is sometimes an electrical problem, as it could be triggered by a damaged electrical relay. You might want to have a professional mechanic complete an AC is not working inspection, so they can determine what is causing this issue you’re experiencing and recommend the right repair.

ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.

ANSWER : If you are getting ready for a long trip and suspect the cooling fan may be not coming on for the radiator and a/c then you should have the a/c and cooling system performanced checked before trip. Nothing worse than breaking down when out of town in a strange area.

ANSWER : Hi There,
The heater not working may be related to the overheating problem you are also having due to a faulty heater blower motor or potentially a bad heater core. As you may know, the heater core is a small radiator like unit that circulates the hot coolant from the engine through the heater core which then uses this warm coolant to heat the inside of the car with the help of the blower motor that blows the warm air through the vents inside the car. When the cooling system is not properly circulating coolant through the motor, this results in the warm coolant not being pumped through the heater core properly in order to warm the inside of the vehicle. In some cases there may be air pockets in the heater core which can cause the heating of the inside of the vehicle to fluctuate between warm and cool air erratically.

Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. As you may know the coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. As mentioned above, this also restricts the warm coolant from flowing through the heater core which uses this to blow warm air into the cab of the vehicle. I would suggest having an expert from Your Mechanic come to your home to diagnose your cooling system.

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 : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

ANSWER : Hello there, thank you for asking about your car. If the turn signal stays solid on the dash instead of blinking, that typically indicates a failed bulb. If the bulb is not the issue, check the connector at the turn signal for both power and ground. It looks like both turn signal bulbs share the same ground point, but the ground side wiring could be faulty. If power is not getting to the bulb, the problem could be the turn signal switch or wiring. I recommend having a professional, such as one from YourMechanic, look into this problem for you and replace the turn signal bulb or switch.
