Hi all,

I recently left my car for a couple years while living overseas. When I got back rats had got in and eaten a lot of wiring under the dash as well a lot of other things. I spent 2 months fixing and re-wired what I thought was all of it, everything is running fine accept the backlight on the cluster and the AC does not stay on.

The issue with the backlight is when I turn the lights on the backlight works for about 2 seconds and then goes out. Ive checked dimmer switch, bulbs are all working, checked gounds ETC.

I believe the issue with the AC is I could never find the end of the Black and yellow wire coming out of the Climate controller, I think its supposed to wire to the ECU. Could anyone confirm this and tell me what wire I need to splice it into again.

Cheers
