I tried searching all the threads but i guess i really need to post a pic and see if my resister is normal. My AC works ok but on the max fan setting, there really isnt alot of air coming out of the vents. fuses are all okay so i checked the resister. and here is what it looks like. sorry for the bad photos, but maybe you can tell me if the little bubbles are screwing it up or what....

does this resister look bad?

 

might want to check your in cabin airfilters if your truck is equipped with them, theres a long door running front to back in your HVAC case pretty close to that resistor that has the filters if equipped...EDIT: that resistor does not look bad....but you cant really tell by looking at them unless they are melted or have exploded inside the case

 

My fan stop blowing on settings 1,2,3... but work on 4 and 5....
ive got to pull that little resistor thingy out and check it..

 

THe originator's post doesn't sound like a resistor, but nonnieselmans does.

Usually what I see with the resistor is melted terminals in the plug area. The resistor may look fine, but the plug looks all melted.

 

Mine was the Resistor.... my buddy got me one from the Dealership he works at... it looked weird and completly different.. but it fit and it works fine now.
