air conditioning problems

Hello all. Well, just bought a 1999 Mercury G.M. from my folks who took great care of it. Well, wouldn't you know, take it off the lot and get it home and now we have a problem, lol. I had noticed the a/c compressor seemed to be cycling on/off the other day so I figured maybe it needed to be refilled. On my way home from work today (1 hour drive), I was a few minutes away from home when I heard a click sound and the temp control center went blank. The fuse blew, ok no biggie yet. When I got home and replaced the fuse, it blew again when I turned the a/c on. I went thru everything that the fuse controls, and it is the a/c causing the fuse to blow. Anyone have any idea what may be causing this or how to fix?? Thanks for any replies..

Re: air conditioning problems

There has to be a short to ground somewhere in the circuit from the EATC module. You'll have to unplug everything on the way out and plug them in one at a time to see which one it is. Not an easy job if you're not knowledgeable on electrical work.

Re: air conditioning problems

great...I don't think I want to mess with it. I guess I will be taking it in to the dealer.

Re: air conditioning problems

I thought I would give an update on the a/c issue. Took it to the dealer and the clutch went bad and seized up, causing the fuse to blow. Actually, once the car was started, you could here the clutch making noise. So a/c here I come!!

Re: air conditioning problems

If the compressor itself is good, the clutch assy. can be changed on the car.
