Cadillac Repair: 1989 DeVille d in climate control and fuel display, climate control, allexperts


Question
I found the question below on the allexperts website, my car is doing a similar thing.  Sometimes it displays a "c" and sometimes it displays a "d".  The fan is on full and will not shut off, and a couple times the service air conditioner light comes onm for a second, then shuts off.  The top check engine light is constantly on, and sometimes the lower service engine light comes on.  Occasionally, it seems to reset itself and is back to normal for a few minutes, then the check engine light will come on again, fan starts blowing, etc.  Is it the BCM or something else?
