Default Blowing fuses

Earlier today, I pressed the cool button, and when I did it blew the CTSY fuse. When I tried to put a new fuse in, it immediately blew it. I guess something is wrong with the wiring for the ac controls? I know some of the wiring on the car has been messed with by the PO who did a pretty poor job on some of it...

Either miswired or a short to ground. The CTSY fuse powers a lot of circuits, one being the heat/ac control assy. I'd first check with an ohmeter if the CTSY fuse goes to the controller and if it does, there will have to be something wrong inside the controller.

If everything was working before you pressed the cool button, try disconnecting the a/c compressor. May have a bad clutch coil.

I disconnected the module for the a/c and heat controls and it hasn't blown the fuse yet. When I had it plugged in, it would blow that fuse. So I guess I need a new one?

Could be a lot of things, the control module or something
downstream from that. Get an FSM and a multimeter
and start chasing the bug.
