A/C going on and off even when all is off???
Here my problem..I have a Acura TL navi 2007!!! and even if I put the blower and the a/c to OFF position....everything is OFF (I push the OFF button).....you heard the A/C clutch and condenser Fan go on and off every 1 or 2 sec generally but sometime it's stop 1 min or 2 and start again each 1 or 2 sec....I really don't know the problem....and when I put the A/C on...it's very cold.....so the gaz seem ok!!!
thank to help me!!!
Oh yeah!!! I forgot!! the output of the ECM pinout E27 send the signal to the A/C clutch and everything is OFF....very weird!!
Some people tell me if could be the navigation screen who control the on or off switch by Can bus signal??? but is it true or it's the Navigation system in the trunk who control that??
Thank you
by the way, it's not a gaz pressure problem or compressor problem and even the ECM who send the signal to the clutch have been changed....the problem is who sending the signal to the ECM to start the clutch even if all the climated control and blower is off???
