There seemed to be many people with CC issues... so I created this thread just for that issue.
I have just completed repairs on two separate CC issues
1. The blower speed switch only working on the top two settings. This was a pretty easy and straightforward fix, replacing the resistor on the blower motor housing.... about $25
2. The air deflector was not operating. Ours blew air only out of the defrost, and would not change when the selector was moved. This was a big surprise. Initially, I thought the CC panel was the culprit ($100) because of the above problem... the two separate issues had the panel in common. But after replacing it, the problem remained. Was ready to replace the actuator...but did some research on Google first. As it turns out, it was as simple as the vacuum hose coming off of the intake manifold. It just "popped" off... and this was the source of vacuum for the CC panel controls. So, I popped in back on...everything worked as it should.
I consider myself lucky to have such an easy fix, though it took a few days to get both issues corrected. I felt that others might be helped by this discovery, and hopefully you have read this before shelling out a non-refundable $100 for a new CC panel...
