Hi All,
I have a couple problems that I think may be related.
First off, I have no spedo or tach indications on the dash, and I have a hard time trying to get a scanner to connect to pull any codes.
Also, the AC compressor will not engage unless I jump 12v to the solenoid directly, even though pressures and the high/low pressure switches are working correctly.
My question is, I know that the circuit to engage the compressor after selecting A/C on the EATC control, utilizes grounds thru the PCM, to engage that circuit.
What are the odds that a bad PCM is causing my gauge/communication, and AC issues?
Thanks guys.
