Hello, I recently removed an aftermarket alarm system from my wife's 2007 Mustang. They used Posi-Taps for the connections behind the module in the passenger compartment and for the power for the module and the system worked, she just hated it. I removed all of the connections, taped over the tap points and started putting things back together. I verified operation of the car along the way, but when I put the console trim around the stereo and heater controls back on, I now no longer have any fan output and the indicator lights for the AC light. I followed the other threads here on the subject and tested all of the source fuses on the both of the fuse blocks (engine & passenger), checked for condensation/corrosion on the connectors on the secondary block unit, checked the connector on the back of the AC control module to make sure that it's connected firmly and nothing seems wrong. I ordered a salvage AC control unit assembly and it also doesn't work. Any tips on troubleshooting further? I've seen the other threads here about the issue, but nobody comes back and reports on what they did to fix the problem. TIA
