Hello fellow DSMers.
I am having a problem with my air conditioner clutch engaging. It used to work fine, then after my 6 bolt swap it seemed to cycle for long periods of time ( on for 2 minutes, off for 15, then repeats ).
Things I have done/observed:
Checked the system charge, its fully charged
A/C clutch engages when given 12v directly, blows cold
A/C relay and fuses are good
A/C relay not getting power
Shorted the dual pressure sensor and temp sensor on the compressor to eliminate them as an issue, still no go.
Tested resistance of the FIN temp sensor, OK
Tested resistance of the blower resistor, OK
Checked the ACCU (AC control unit), it looks brand new, nothing burnt or shorted.
I know that there is a way to check if the ECU is grounding the relay, but I am not sure how. I dont not want to destroy my EPROM ecu with dsmlink, so does anyone know how to check this?
Or if anyone has any other suggestions (other than ripping the whole thing out), please let me know.
Thanks!
