Re: AC Request
im using a E38 Gen 4 PCM.
still fighting this.
I know the transducer switch on the high side line is working and getting a 5v ref and sending out a voltage as related to the pressure, but I still can't get the ECM to read it with HP Tuners VCM scanner.
I have a segment swap done for the fans, just dont know if it's the right one. As this ECM originally came out of a Chevy Express 3500 with a clutch fan.
The fans are working correctly, controlling engine temps, but are not working to control ac head pressure / temps when the engine is under minimum coolant temp for the fans to come on and I blow the relief valve on the ac compressor.
