Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 GMC Envoy Owner Comments

problem #1

Jul 162010

Envoy not sure v-6

  • Automatic transmission
  • 119,206 miles


Why should i be responsible for repairs on my envoy. the wiring harness that connects to a resistor for the Blower for the A/C is getting to hot and is starting to melt .causing the blower to stop working. Not good when you have to commute 35 miles one way in 100degree heat.Not only is it not good but also a fire hazard. there should be a recall on this because of endangerment to life and automobile .

Update from Aug 5, 2010: It cost near $300 to repair . I am hearing that this same problem occurs alot. Most business thrive on repeat coustomer .I can assure anyone that this will be my last GMC product i will ever buy.They do not stand by there product nor do they listen to the consumer. The mechanic said that the blowers are or shorting out which can cause the resistor and wire connector to heat up and melt. I will say i am a very unhappy coustomer......................
