Ac problems

[Patrick Williams]

I have a 2004 g m c Sierra an the ac just stopped blowing all together so i found another hot wire an spliced it an made a jumper to the blower an the ac only blew on high but worked great now some how my wires got ripped out an can not get blower to turn on again i took blower out an hooked it to battery an blower worked great attempted to reinstall blower hooked power back to it an nothing only on speed 5 did i hear a clicking from resistor

Usually when the blower only works on 5, that is because you are bypassing the resistor and giving it straight power. Replacing the resistor fixes the problem just about every time.

So if the blower is in working order as it is being i hooked it to the battery an works fine all fuses are good you think the problem is the resistor ? Could there be any other reasons for blower not to turn on at all 

[CamGTP]

A bad control panel could stop it from working too.

 

I'd be looking at the resistor option first before that.

Ok i am just wondering being i have ruled out it being the actual blower itself or fuses only possible things are control panel meaning the controls or the resistor
