Re: Is this a A/C blend door problem?
Sorry it took me this long to post the results of replacing the part. I wanted to wait until after my extended road trip to give the problem ample time to resurface -- if it was going to. But I'm happy to report that I have not seen a single reccurance of the problem since replacing the termperature control panel. So I'm going to declare victory and call this problem fixed.
For reference, the part number and description on Jeep dealer invoice is:
55115904AC "SP Control-A"
The cost was $130 plus tax.
Good luck to those of you still experiencing problem!
