Follow up to my previous complaint about the fan controls not working. Temps dropped to 20 below zero and the fan finally had enough. Of the five speeds for the fan the only speed that worked was #5. I bought a new resistor for the fan. Initially bought the part from Oreilly Auto parts in Forest Lake, MN. The salesman was eager to sell me the part, but of course failed to mention that it did not fit on my truck. I returned the part and he claimed I needed to "reconfigure" some things to make it work, or go and by the GM part. In an attempt to be funny the other salesman standing by the counter said "If it wasn't for the newer Chevy, Ford, Dodge and Toyota trucks, we would be out of business"....what a funny guy. I gave him his part back and went across the street to Napa where the salesman actually told me upfront that the part wasn't going to fit properly. Long story short, two washers did the trick to help secure the resister where it should be. The resistor is located under the glove box.

Lower speeds on AC/Heat control stopped working. Only speeds 4 and 5 work. Not the end of the world, but it is really annoying.

I started by loosing my lower speeds on my fan, then got 'till i only had the high speed on the heater. It took a while to figure it out but i finally got it.

my battery went dead because I left ignition on, after getting truck started the heat was as hot as on high, moving then temp control did nothing, unable to divert heat to the floor or windsheild, also AC will not turn on, or back window defrost. ANY SUGGESTIONS OUT THERE??

ok, this really pisses me off. My truck, my daughters trazil blazer and a friends trailblazer all 3 of ours have had this fan problem. It only works on 4&5. This is a definite problem. Chevrolet does not seem to care that we buy their junk and pay damn good money for it. To have to replace the fan switch. Plus other things that have to be replaced. As much as I have loved Chevy I am def looking at fords. This is terrible business for chevy not to replace these heater fans.
