I was shooting for power today while I was installing an alarm in my 2003 tacoma ext cab and I heard a pop and realized that one of the connectors for my a/c and heater panel had touched a screw and one of the wires had shorted to ground. The wire that I think touched was a WHITE/ black stripe wire, about 12 gauge. It's an 8 pin connector (if I remember), of which only 5 pins or so were installed. Does anyone know where this wire goes to? I checked all the fuses I could find and everything appeared to be ok. I shot that wire for power after the incident and it reads no power so I obviously blew a fuse or melted something. Any help would be greatly appreciated. matt

the connector that I'm talking about hooks up to the left side (from drivers seat) of the back of the a/c and heater panel.

If you checked all of the fuses and none are blown, you may have blown a trace on the circuit board for the ac.
By the way, has anything stopped working?

I haven't reinstalled the panel yet to test it out, but I checked again for power on that wire and it read nothing. I was worried that I might have damaged something a little expensive. I guess we'll see tomorrow. I just figured if it was a 12 gauge wire it would be fused.

Yeah, don't worry till you check to see if everything works. Once you find that out it will be easier to track down a known problem.

I just reinstalled the panel and sure enough, the A/C doesn't come on, but everything else on the panel works fine. I shot for power and there's another pin going to that panel that is also power, so everything else must be running off of that. I checked the a/c fuses under the hood and they are all good. I removed the fuses and shot for power at the fuse panel and there's power there. Without a wiring diagram I'm kind of stuck.
