Your engine needs to get hot, to be able to give the heat to the heater. Assuming that is fine, then move your diagnostics inside to the heater controls.

If that works correctly, then your problem is obviously in the automatic control piece, and I would look first at the sensor which monitors the cabin temperature and feeds back to the unit whether it needs heating or cooling.

I cant get my a/c compressor to engage on my '94 LS Saturn. I have 45 psi on the low side of the compressor. When I press in the a/c switch on the dash, the switch lights up but the clutch does not engage on the compressor. It appears that there is no current getting to the solenoid, yet both a/c fuses are good and the control relay on the circuit breaker panel is good. any ideas?

Replying to: saturnowner1 (May 31, 2009 6:08 pm) Also your pressure is too high. Maybe the switch shuts off on too low AND too high pressure, I don't know. About 28 to 30 PSI on the low side at 70 degrees F.

Replying to: Mr_Shiftright (May 31, 2009 6:17 pm) My pressure is in the blue on the low side meter (i'm guessing that was 45). Any idea what my next step is? can I go straight from the solenoid to the a 12v source and see if it turns on? or is this something that needs to go to an a/c expert?
