I replaced the thermal cutoff and the rear a/c now blows just fine. So fine that I cannot get it to turn off, even with the front controls off and the front a/c completely OFF! The rear rheostat doesn't function either. Could there be a short in the transistor? I'm thinking the rheostat is/was broken and shorted the thermal cutoff instead of overheating the rheostat--any thoughts????

Just trying to help out here. If your front or rear A/C just stops blowing one day and had been cooling fine, then it might be the thermal cutoff inside the transistor assembly, which is a DIY project. There are instructions here, and even better ones at mdxers.org, at the Problems tab. My thermal cutoffs arrived yesterday from Digikey, and after soldering each of them in the assembly, both the front and rear A/Cs are back in business. If you cannot do the soldering, then even replacing the entire assembly will save you a lot of money over having the dealer install it. Hope it works out.

If the engine/coolant is "tending" toward overheating the A/C compressor will be disabled.......sounds as if your radiator cooling fan(s) might be on the fritz.
