Hello and thank you in advance for the help, I greatly appreciate it. Winter is almost here and my 90 Iroc-Z has been converted to a 383 carbureted motor without a/c. Because none of the a/c electronics are hooked up, my blower does not work so I cannot even get the heater going. I've tried to find info on this and all ive found is that maybe I have to get an a/c delete blower, but is there any way to get mine to work? If not, can someone who has done the swap provide some insight into what i would have to do and where i can get a box? Again, thank you for taking the time to save me from the cold Missouri winter!

 

Does the blower motor not work at all? If not, have you tried testing it?

 

the blower motor worked before the motor swap but now the controls dont turn it on or off, but im sure the motor is still good. I just assumed that all the a/c wiring that is now just loose wires has something to do with it.

 

Might check the wiring splice connector to you fan. It's not easy to see from the topside but, it's located in the engine compartment between the motor and down behind the passenger side strut / inner wheel housing. These splices are sometimes disconnected when an engine swap happens. Did you also swap wiring harnesses?

 

I did not swap wiring harnesses, and I havent checked the connections you mentioned. I'll check them out and see whats going on there.
