Yesterday my a/c wouldn't turn off on my car, even after I turned off the car. After a slight electrical burn smell on my way home, it shut down last night. But this morning, again it wouldn't shut off once I started the car. Had to disconnect the battery. Other replies say to replace the a/c relay switch that's located by the firewall. Problem is I'm a woman and not all that familiar with this, and need pictures or a better description for what I'm looking for. Is the relay box on the bottom of the cruise control box under the hood? What exactly should I order from the parts dealer? Is this an easy plug in part? Does anyone have a picture of what the relay box area looks like?

I tried to pull out the box that's located underneath the large fuses under the hood. I got the second one loose, but both boxes have wires attached behind the box (2 red, 2 green). So I decided I'd better check to see if this is in fact the relay switch before I go any further. I did, however, pull the large fuse in this area that goes to the AC. So at least I can now shut the car off and not have to disconnect the battery to get the AC fan to go off. I'm submitting a couple of pictures (sorry about the blur and the night time pictures). You can see the box that I've pulled loose from the holder (under the red colored fuse). Am I going for the right part?

Let me reverify this are we talking about the blower motor fan or the AC condenser fan?

Underneath that red fuse is for the high speed blower motor relay for a buick left of it is the blower motor relay for an olds and pontiac

I think we're talking about the AC condenser fan. I can turn the AC off in the car and the AC fan continues to run. When I shut off the car, the AC fan continues to run (initially I disconnected the battery when I parked the car, then I discovered the fuse to the AC under the hood (a large sized 10 A green colored fuse) that I could pull out to stop the fan so I wouldn't have to disconnect the battery. This is great, but now I have no AC. I bought a new 10 A fuse, but that didn't fix the problem, the AC fan would still blow continuously, so I pulled the fuse again. What do I need to replace to fix this problem. I thought it was a relay switch, but I'm not sure where that's located or what it looks like. I really appreciate your help on this!

VIN K The AC compressor is at no.3 and VIN 1 is at no. 10

If it continues to run-get the HVAC control assy and the computer checked out to include the blower control switch-You have a dead short somewhere within the AC circuitry.
