Ok, I deleted my AC and installed a non-ac box w/ its respective blower motor. It seemed everything pluged directly in with no probs. only prob i ran into to the resistor was cracked on the non-ac box so i pulled it out and used the resistor from my ac box. After it was all together i flip the climate controls and i pop fuses! my interior lights go out as well as my stereo. I must have something hooked up wrong. Any sugestions or something obvious?

 

maybe the resistor you swapped out is different between the two boxes. Try to get one for non-ac and they try it again.

 

easier said than done... where an i gonna find one of those?

 

go talk to your gm dealer...it will probably cost too much though

 

Any jobber should be able to get you the blower motor resistor, AutoZone even. But check to see if the a/c car and non a/c car use different resistors before you waste your money.
