Ok so I was inside my truck with it running today and cranked the ac while i was vacuuming it, cuz its 100+ deg. outside, and all of a sudden the ac stopped blowing, and i smelled like an electrical fire smell. Ive smelled it before so i know what it smells like. Seems to hasve been from the passenger side, so i shut the truck off and looked for smoke and noise etc. I checked under that panel on the pass side of the dash to see if anything is cooked, but seems to be fine! My ac works fine on settings 1-4 on the ****, but when it clicks and hits 5, it shuts off completely...any ideas? hurry!

 

could be A/C high blower fan relay.

 

Replace the blower resitor and connector, its a common problem

 

I thought that the resistor was only in the circuit on lower speeds. Isn't high speed a full 12 volts?

 

high speed also travels through the resistor pack since the blower motor plug comes from the resistors

as said befor do the resistor pack and pigtail- when you pull the connector off most likely it will be burnt up

 

you will have to check your fuses in the underhood fuse block. when the connector melts it usually takes out the fuse for the high speed.

 

Checked the fuses, everything looks fine, but which ones the high speed one? I need a how to and where these components are located asap!!!

 

what the hell man my ac is doin almost the same thing in my 05 RST but i get no blower speeds when i get goin i can feel the cold air comin in i check the fuses under the hood they all seemed good mine went out last thurs tyler when did urs go out

 

its kind of ironic that our ac in our 05 rsts are doin almost the same thing at the same time

 

last thurs too hahahaha thats wierd as hell- 21,500 mi
