Kevin, Your AC vent and no heat problem is most likely caused by a defective AC Mode Switch. The best action is to replace this part with the updated version part# 100752G which includes an ac compressor "on" function in the defrost position.

In 12/97 DMC-Houston did a lot of work, hoses and things (totalling about 6 grand- I said a lot of work!). The cooling fan does not seem to run all the time, but the engine temp has never been up over 200. The AC does not run except on the AC settings (I can tell by the engine load). > > So I think maybe I am seeing two problems: 1) the cabin airflow is stuck on vents, 2)perhaps the water pump runs all the time? I don't know, that second one may be way off.
