Rear a/c won't work on 99 Durango

My rear a/c won't work. Like nothing happens, its the top seperate a/c from the front (which works fine). It just stopped working one day. I had all the fuses and connections checked and it that all looks fine. Any suggestions?

Check for power to the connector (you'll need a Haynes or other manual & know how to use a volt meter).

If the power is there, it sounds like you have to change the motor. That same manual should show you how & provide more comprehensive trouble shooting. Good luck. It's got to be a lot easier than changing the main heater/cooler fan motor under the dash.

Here is a pdf on the wiring.

But take note on the switching and controls use a ground circuit to work it.
Power should be on on side of blower motor with switch grounding the circuit to turn blower on.
Let us know how it goes.

I bought one of those Haynes manuals and am hoping to dig into it this weekend or next. Thanks for the great suggestions, I will give it a try and let you know how it goes.
