Well, I thought my A/C was gone when it strangely quit on me and switched to heat mode all of a sudden. I notice that it did this shortly after I was accelerating.
Apparently the transmission was trying to kick-down into a lower gear, but it didn't. This, in turn, blew the fuse that operates the climate control valve. This fuse also operates a host of other functions in the car, and yet, it is still only an 8A fuse.
Of course, the actual A/C fuse wasn't blown, but it does get hot (its the only 25A fuse). It has obvious signs of melting on both the housing and the fuse it self.
All this fuse blowing is starting to make me suspect that my 23 year old car has a few electrical problems with it. Nah, couldn't be.
On the positive side, though, I did fix my rear passenger window that quit working. Thanks to a "how-to" on this site. Thanks Karl.
