Our car has the front and rear a/c units.
The other day a solenoid in the left rear quarter panel started clicking. This is where the rear fan, etc. is located. It sounds like a very large clock ticking
You can turn the rear unit on with either the front control or the rear control and the clicking starts. Turn off - no clicking.
The fan runs at all speeds and the rear unit seems to be cooling.
Anyone know what this is and how to fix it?
About 35,000 miles on the car.
