Q: AC works partially, depending on low or high setup

asked by on

Hi. I've been having problems with the AC not working correctly. It works only partially and I need some advice on how to fix it. It changes the way it works depending on the settings. If it is set up on high, the vents on the passenger's side blow warm air, but the driver's side gets cooling. As for the low set up, the vent on the back seat and the vent of the front windshield blow cold, whereas the front vent doesn't work at all when set on low. Do you have any suggestion how I could fix this? Thanks.

The AC system uses a variety of actuators inside the ducting system in the car which control things such as what vents are used and whether the air is hot or cold. It seems most likely that the mode selector actuator has failed for you car. When this occurs, it exhibits symptoms like you have described. If you want to have this verified, a qualified technician from YourMechanic will be able to diagnose your AC issue and perform any repairs that may be required.

Q: Heater still blowing cold air?

When cooling systems are re-filled (after thermostat replacement for example) air can get trapped and that trapped air can prevent normal circulation of coolant. That, and low coolant level, would be the first things to check. If no problem is...

Unless the engine overheated, the head gasket would not necessarily be damaged by running low on oil. Ticking type noises are usually associated with wear in the valve train. In some cases, low oil pressure will be the cause of...
