Please help with the following so I can try to fix my a/c issue.
1) Can someone confirm that the 335D air conditioner variable compressor is controlled by a pulse with modulator signal from the computer? If so, is it a 12 volt signal or a ground signal?
If the compressor is controlled by a pulse width modulator signal either 12 volt or grounded signal, Then it probably has 2 or 3 wires going to the solenoid that controls the compressor output. One would be a control wire, one would be a feedback wire and the third would be a permanent ground wire or switched 12v supply wire. Could someone with a wiring diagram look up the wires to the a/c compressor and let me know the wire colors and where the wiring diagram shows they come from so I can try a work around fix.
I plan to purchase a pulse width modulator and use it to turn on my a/c when the car is first started. I am going to also get a 5 to 7 minute timer circuit to turn off the pulse width modulator after about 5 minutes so the car's computer can control the a/c the rest of the time.
