While driving the vehicle in town on a city street at approximately 35 mph, with the ac on and the blower in the high position, the blower started turning off intermittently. A smell of burning plastic was noted and the blower completely shut down. The compressor for the ac continued to cycle on and off. The other lower settings for the blower did not work either. It was found that the plug that goes to the resistor pack next to the blower had a badly-burned contact for the ground wire going to the blower. The plastic around the plug was melted and burned and the electrical connector was melted off. A serious fire could have potentially started under the dash due to the intense heat and arcing of the electrical contacts putting me and my family in danger. Doing research on the NHTSA website, this seems to be a common problem with 2005 Chevrolet Silverado trucks. There should be a recall on this, but I do not find one.

Driver side seat heater turns on by itself. This is a dangerous situation because the driver is distracted while driving and must look down to find the off switch. Often, the seat heat comes back on again almost right away.. this situation seemed to occur in approx 2003 to 2007 models. Internet forums show that GM has service bulletins that instruct technicians to do a 'firmware fix". the only way for me to stop this condition was to locate and disconnect a small green connector under the seat that disables the seat heater. Changing the control module didn't remedy the situation. It happens while driving and is intermittent. Seems like GM has remedied the situation in newer models. Seems to me they should be recalling older models to incorporate some sort of "fix". the distraction of locating and turning off the heater is as bad as "driving while texting". I always have to pull over to get it shut off. Often, when I resume driving, the heater will come back on. Eventually it stops turning itself on.

The speedometer is very erratic sometimes showing a faster speed than traveled sometimes a slower speed or no speed at all the odometer has since quit working and displays odometer error where the mileage should read. And now the engine water temp gauge is dead pointing straight down where there are no numbers and never moves. Dealer where I bought the truck new says they have repaired quite a few of these and will cost around $350. To send it out to be repaired by a qualified repair place. I think G M should stand behind such a problem and recall these trucks to fix them.

The contact owns a 2005 Chevrolet Silverado. While the vehicle was parked with the air conditioner set on level five, the blower intermittently clicked off and on. The contact also stated that a burning smell emitted through the vents of the vehicle. The failure recurred on several occasions until level five and four settings no longer worked. The contact inspected the connector sw/power St adjuster and discovered that the wires were melted. The vehicle was taken to the dealer and was not diagnosed or repaired. The dealer informed the contact that the connector and resistor for the air conditioner and heater and the resistor for the heater needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 97,000.

The wiring harness for the heater blower motor resistor melted and this has happened twice now causes smoke and you loose the heater function. Not sure if it could get hot engough to start a fire.

I purchased my 2005 Chevrolet 2500hd duramax in may of 2015. A week later I was pulled over for speeding 10 over. My truck showed I was driving 55 mph. I now have a speeding ticket $114. I contacted GM about the issue and they said my VIN# was not qualified for the recall and I would be paying out of pocket ($535 including labor). The part alone is $350. Now at the end of the day I will owe $649 because of GM's mistake. I love GM's products, however they do not stand up to there mistakes which will make me think again before buying one.

The brake lines and fuel lines rusty to the point that they are leaking need to be replaced.the blend motor for HVAC isn't working right.

I noticed this past weekend that my speedometer started to malfunction....along with the oil gauge, & battery gauge. They all were pegged out & not reading correctly. The tachometer seems to work still, but it is hesitant at times too. The speedometer had a issue a couple months ago, but it seemed to disappear until this past weekend. I would think there would be some type of recall on this after reading all the issues people have had in the past. Yes, this truck is 8 years old, but when I bought it only had 22,000 miles. I have only had it about 10 months & only put 9,500 miles on it.

Was driving down road looked down at my speedometer and it was pegged out over 120 mph I was only going about 15mph so I stopped and turned off truck and speedometer went down to 60 not 0 as it should I turned it back on and took off it did same thing all way over 120 mph so when I got where I was heading and turned truck off again same thing just dropped to 60 so I kept turning key on and off and it would drop about 5mph each time until it got to 0 went to dealer he said lot of problems with this model truck I would need a new dash and it would cost me $1200 I think GM should fix these truck it the law to have a working speedometer on your truck thank you.

2005 Chevy Silverado 2500 hd duramax, speedometer stuck on 23 mph. Known issue with faulty part, the instrument cluster stepper motor. GM will not cover replacement. Faulty parts used from 2003-2007. Class action suit only covered certain VIN numbers and no recall was done. Safety issue/concern. Was informed by dealership that if we had brought it in 8 months earlier it would have been repaired at no cost. Never received notification of potential for this to happen. There should have been a recall...
