I had an air conditioning problem with the flap so i fixed that , now i reach under dash and the wires are very hot? Anyone have this issue to help?

Wires "getting hot" may not be abnormal. Circuit protection should be in place with the proper amperage fuses so that any overloaded circuit will blow a fuse before damaging wiring or wiring connectors or components. Ensure all harnesses are unharmed and not damaged, all wiring connectors attached and free of melting and burnt terminals as it is. More resistance can create more heat!
