AC help desperately needed (1 Viewer)

[Rookie44]

Update: I have battery voltage at the AC switch. Regardless, of whether the H/LP switch is bypassed or not. Without the bypass, I have no voltage to the Compressor. With the bypass, I STILL have no voltage to the compressor.

With that known, Do I tear into the dash, find the Thermistor and bypass it? Or is the Thermistor ok if I have power at the fuse?

If the Thermistor is OK? Where do I turn now?

Bump....... Anyone..... Buelher.....

I would bypass the thermistor and report back. Location is under the glove box and left. I think I mentioned more specifics early.

The switch located by the drier is a trinary switch, so it senses both high and low pressure, and will shut the compressor off if the pressure is out of spec in either direction. Have you checked for power at the switch?

As for testing the amplifier:

Terminal Specification
6 & ground------------------continuity
8 & 9-----------------------continuity
2 & 6 A/C switch "ON"-------battery voltage
2 & 6 A/C switch "OFF"------no voltage
3 & 6 A/C switch "ON"-------battery voltage
3 & 6 A/C switch "OFF"------no voltage
5 & 6 start engine-----------10-14 volts
5 & 6 stop engine------------no voltage
9 & 6-----------------------1500 Ohms (@25 degrees C)

Another possibility, you may have already checked, is the clutch relay.

Need some help. 3/6 always have battery voltage 5/6 no voltage ever

Amplifier just bad or something else wrong?
