fitted a power fc to my ep85. one issue i seem to have found is that the a/c is always registering as being on, unless the fan cuts in!!!!

i have removed the aircon, but i dont get this issue on my ep82!?!?

only difference is i have removed all the electrical crap thats not needed around by the aircon condenser behind the glove box.

what actually tells the ecu that the aircon is running? is it something somewhere on that short bit of loom i removed? i want to just either ground it out or put 12v on it whatever way it works, then i wont have the issue.


thanks

If you've got +12v feeding the AC1 pin of the ECU, it'll think that the A/C compressor is running.

all sorted. traced the wire back to a unit on the dash support bar behind the glovebox. has a blue plug. removed that wire from the plug and its all good now.

strange i only get this issue on this car and not my ep82 :S

thanks for your help :)
