Just like the title says, I have a 1992 RS that I swapped out the 305 TBI engine from and swapped in a 327 Miniram with the TPI wiring from a 1990 Camaro. The car runs great, everything works excellent except that I now have no Heat or A/C, the blower motor won't turn on. If you turn the heat on warm air will flow out only if you are driving and I can divert the air to defrost, vents, ect. , but no blower motor. I had Heat before the swap, now nothing. Anybody else have a problem like this !!!!

 

find the wiring diag. and recheck your wires, maybe the back side of the bulk-head plug is wiried diffrent

 

No easy way but to trace the wiring.
