what causes the A/C to cycle?
What causes the AC to cycle on/off? I believe my AC used to cycle when it got extremely cold, but now its cycling when its just beginning to get cold. The AC fan cycles together with the compressor which tells me its not the pressure switch or the temperature switch mounted on the compressor because the fan should stay on during the cycling if it were the pressure or temp switch. Ive tested and have 32 psi on the low side which is plenty.
Also, the AC switch itself has 2 modes:
-1st push = yellow light
-2nd push = green light
There has to be a reason to have 2 modes, but Ive never found any difference between them even when the AC was working properly
Car is 95 Tsi AWD... I used to have a 97 GST and it didnt have the 2 mode AC switch, only a green light when pushed on
