Hi-We have an e24 auto. that we bought from the original owner a few years back here in Northern California. Has about 125K miles on it today. Was not a daily driver, could have been though. It was all good. For a along time, the a/c was blowing properly and all, just not TOO cold. Figured it needed a freon re-charge. The heater/defroster seemed to work fine back then too. So at some point after buying the car and driving occasionally over many years, the a/c quit blowing any "cold" air whatsoever. That's sort of okay, but now it seems I can't get the heater defroster to blow warm air either. The fan blows very well and at the appropriate volume one "dials in." Is this that the "heat/cold control valve" gone bad? I appreciate any good advice a whole lot. Thank you very much.
