Ok, So hear is the deal. I have a 91 Formula Firebird, and the A/c - Heater will not blow at all, this has been a problem for awile and i cant figure out what is wrong with it.I have replaced all the Relays and Resistors, the Switchpanel, and tested the blower motor and it works fine. With winter just around the corner id like to get this fixed.A Little Help Please?TY in advance for everything, Deadd

 

Been there an wound up in the same place, my fix was to wire a toggle switch on the dash to send a full 12v to the blower motor directly.

Which is about twice as high, as high. Blows like crazy.

 

Mine had a bad ground on the fan itself..

 

Thanks for the imput, im trying to look for something that still will make this work properly im looking to make this into a show car, If there is any other suggestions please let me know thank you

 

Just fake it, do like I did but hidden, using the stock stuff but wired direct.

 

oh i got it just use the 12v source on a toggle and use the factory controls, it will all still work just have a little more juice cause of it getting pure 12v?

 

Yea something like that, it will run faster getting a full 12. But you should be able to hide everything just fine and make it look as if it works like stock.
