Disconnect the blower motor, replace the fuse, and if the fuse no longer blows, the blower motor is likely drawing too much current and needs to be replaced.

In my 79 I had problems with the climate control a few years ago. Try searching this site for info on 1979 climate control and maybe you can find some of the posts. Anyway, I learned the 77-79 Cads had problems with the climate control wiring harness actually melting which causes all sorts of malfunctions. In my car my climate control would run even when the car was turned off! Other problems happened too - - I can't remember them now because the problem was corrected. A helpful person on this forum named "Ape Man" helped me get this handled. I haven't seen any posts from him recently but he knows all about this vintage of Cads. Good luck! I'm not very mechanically inclined otherwise I would be able to tell you more. Dave
