The fan on the Heater/AC in vehicle will stop working intermittently. Other times, when it is working, the fan will stay running even when vehicle is turned off and the door has been opened.

Silverado WT 3.2L V6

  • Manual transmission
  • 70,000 miles


GM recalled this and sent me a form to fill out and they would pay for the part if I fixed it, I done all this and put in the new part, sent the form back and as they said they would do, sent me a check for 30.00 bucks, the resister lasted 2 weeks and is right back like it was, the blower will work in only the first 3 positions of the switch! I need to know if there is a part that will last a bit longer then 2 weeks!

The blower motor for the heater system is not working correctly. Sometimes it won't turn on at all. Sometimes it won't turn up to full power. Sometimes it doesn't turn off even after the power is off and the door is opened.

problem #10

Nov 112011

Silverado V8

  • Automatic transmission
  • 40,000 miles

I have owned three full size chevy pickups

1995 = Chevy 1500WT - no issues period 200,000 miles, brother stills drives it at 300,000

2005 = Chevy 2500HD - Because the first Chevy PU was excellent. Multiple rear seal issues, and HEATER BLOWER FAILURE THAT COST $350 after 25,000 miles. No help from dealer or GM

2006 = Chevy 2500 - Blower motor loses level 5 at 20,000 and then total failure at 40,000. How can this continue from year to year. What does the good part add to the sticker of $30,000? This is why we lose faith. It's NOT the issue per se, it's the reaction to the issue. I thought I would be a chevy truck guy forever. My next one will either be a Ford or Toyota. Sorry GM you have bigger brain than I do so there must be a logical reason that loses a customer because of a single insignificant electrical component.

problem #8

Sep 012009


  • Automatic transmission
  • 68,000 miles


I bought my husband his 2006 2500HD truck. This was the most expensive thing he has ever owned. Much to my dismay, the electrical component under the passenger side, that regulates the heat is melted and will only allow the heat to come on sometimes. No recall for melting electrical? I hoped that Chevy would not lose the quality of their trucks, but even my staunch Chevy husband is rethinking his next truck.

As I learned from another post, it is going to cost $350. Well, I guess this is what we get when the government runs things. Haha. At least this makes the annoying buzzing from the door open (when the key is not in ) seem not so bad. I wonder what else is wrong that I don't know about yet. That is a scary thought!!!!

Now the blower shut off once got it going again by pulling the fuse and putting it back in and it came on.Now today it wont work again.I think Im going Ford shopping this weekend......

Silverado LS 4.6L

  • Automatic transmission
  • 78,000 miles

The fan blower has five stages and some time there may be access to only three and every once in a while it may go to 4 and or 5 but the majority of the time only 3. This is extremelt annoying when you are trying to cool down a 100 degree plus vehicle.

Silverado LX 4.8L V6

  • Automatic transmission
  • 58,977 miles

Why in the hell hasn't someone from GM fixed this problem??? It isn't like it's NOT a commonplace thing that happens somewhere after the 40K/mi mark, as I and my friend have the same exact thing going on with this shoddy resistor setup/wiring harness malfunction on TWO separate trucks(an '05 & '06). Shouldn't Chevrolet offer an upgrade replacement? I think so!! It would be an easy fix too, using a 12V MOSFET electronic regulator in lieu of the crappy, cheap, and ObVIOUSLY defective ceramic resistor setup in place(which keeps FAILING>>>).

Just my two cents...

Silverado LX

  • Automatic transmission
  • 32,000 miles

I bought two 2006 Chevy trucks, they both are having the same problem what a coincidence, the dealer shows no recall I guess I'm stuck with the bill what bullshit seems the same story with all dealerships, Should of bought a Toyota I guess at least they will recall their screw ups!!!

problem #3

Aug 222009

Silverado LX V6

  • Automatic transmission
  • 51,000 miles

Mechanic stated that this was a common problem with Chevrolet's. Pissed that I had to pay $332.00 to fix the A/c on a car that is only 3 1/2 years old with approx 50,000 miles. Scares the sh*t out of me on things to come!

problem #2

Jan 152009

Silverado HD Diesel

  • Automatic transmission
  • 35,000 miles

have 3 Chevrolet silverados 1500, 2500HD, and 3500. ALL 3 have heat fan problems... Intermittent to not working at all, all start by loosing blower fan level 5, then 1-4 work intermittently then not at all. Not too bad driving in the 7 below zero weather, except in snow when you can't clear the windshield. Was told by dealer after we personally changed the entire heat control unit in the dashboard twice on the 2500HD, that alone will not solve the problem, that the blower resistors heat up and melt the connector cord in the back. It's 117.00 for the blower resistor replacement, $70 for the new heater control unit in the dash and 1 and 1/2 hours labor and this should fix the problem as they have new resistors that won't heat up and melt the connectors. Total cost avg 350.00. I would think this would be a recall issue since melting connectors, and not being able to see could be safety issues, but I guess with the cold weather a little "fire" might be nice to thaw me out while driving . :)

Silverado 1500 V6

  • Automatic transmission
  • 60,000 miles

the blower fan at times just stopped. this has happened twice now. the last time it smelled like electrical, then it started working again. 3 months later it stopped again for 20 minutes and started again. the dealer cant fix it because they say its not happening when they have the vehicle.
