I have a 98 Crown Vic Police Interceptor. By mistake, I hooked the jumper cables up backwards and smoke came out my dash. The radio no longer works, and I only have HOT air blowing from the vents. I was just looking for a place to start to look for the problem with the AC. THe blower works fine and the HEAT works too good!!! But without a large service bill I just wanted to know what to check myself (hopeing it is a small problem with and easy fix) before I take it to a mechanic? Thanks

 

HVAC heater blend door actuator.Which is located behind dash!Good luck
