My AC has taken to working when you start the car and sometime after that switching OFF then after a few minutes switching back ON. This started last year in the fall.
It is the fan that stops and the cold air turns to ambient air temperature. I do not think the temperature slowly lowers, I think it basically just stops blowing cold air and it is hard to feel the temperature of the air coming out the vent.
Sometimes the fan stops for less than a second and then carries on normally until it stops completely.
There does not seem to be any fixed time after which it restarts. Turning the dials and thumbwheels does not trigger any action.
I cannot find a solution or a similar question on here before.
When it is ON you can select the fan speed and the temperature to both sides.
I took the PCB (board) off the back of the control panel and filed away the PCB so that it fits into the notch without interference.
I did not add epoxy glue to hold the PCB board to the control panel figuring that the contacts fitted nice and tight.
I cannot say that the AC compressor stops or not, as it happens when I am on the highway and stopping is often a bit of a problem, also it may just start up again but I'll try to do it sometime.
When it stops working the interior of the car heats up pretty quickly and having my centre dash apart there are no window buttons fitted at the moment, the temperature this afternoon read 87° on the dash.
Anyone out there with an idea? Does the temperature sensor on the lower grille have anything to do with the AC?
This is just the third time I have driven the car this year and it happened every time, I kept forgetting that there was a whole gang of experts I could ask.
I know next to nothing about the AC system.
