I got caught in a bit of rain yesterday and ended up hitting a puddle of water that was deeper than I expected (an ambulance was running code in the rain, so I figured it was a life/death situation and got out of the way). Anyway, immediately afterwards, the temperature sensor on my dash dropped to -40F and started flashing and the A/C started blowing hot. I got home and found a wire dangling loose under the front driver's corner. The wire is on the same harness as the horn and driver's side fog light.
I posted on another BMW site but responses are slow. Was hoping somone here could shed some light.
I have read that the A/C system is computer controlled on the E46, and that this sensor if unplugged or damaged would cause the computer to block the compressor from engaging.
Any ideas where this third wire plugs into? I've checked my Bentley manual and I am either missing it or its not there.
Thanks in advance.
