I'm now into the first trip in my "new" '87 300TD and I'm discovering all the interesting things that can't be learned in a test drive. In this case the vents on the front dash have shut down twice after about an hour of driving in AC required conditions. The first time it was just the center vents and I was able to get them open again by hitting the max fan override button. The second time the whole dash shut down, no defrost air, no side vents, no center vents and no foot air. I tried the max override button -- no luck. I tried turning the temp up to kick the heat on -- no dice either. It finally came back to life after sitting for half an hour at the grocery store.

I searched the forum and found lots of interesting and useful discussions on the climate control, but none seemed to describe this problem. Any ideas?
