A/C wiring messed up

[VAE30FTW]

My A/C for some reason doesn't work.



I removed the plug above and tried jumping it. Everything came on but the jumper got hot quick! any reason why? Could the aux fan be short circuiting stuff out?



^that's some sort of ground loom I assume.

It sounds like there is a short downstream of the slider switch. Use the wiring diagrams at http://wedophones.com/BMWManualsLead.htm to figure our where.

I'll take a look and report my findings. doesn't look like fun...

Well the brown and green wires are 12v. those are fine. then the white wire goes directly into the A/C switch.

Well found the cause



As you can see I closed the switch slider. I'll just place an inline 1.5amp fuse in there.

The fix



Disconnected the wire going to the alternator. Still need to test the a/c clutch for issues. Maybe the A/C diode is grounding out and faulty? Any thoughts?

EDIT: I think it needs a new a/c clutch. What are my options?
