I was recently rear ended a few weeks ago and since that time My climate controls don't work and the display either never appears or flashes incoherent numbers. I took to the dealership but they are basically clueless here at the only dealer in the city. I suspect there is a short somewhere but the connection from the Climate Control circuit board to the harness is in tact.

Any suggestions for troubleshooting greatly appreciated

 

Turn your compass off. Does this fix the problem?
