Wont crank, running hot, heater blows cold air


Hi Angela. it sounds like you have a belt proble causing your alternator to not charge your battery AND your water pump and fan to not cool properly. Inspect your belts first. If you have more questions please ask me!

My 2006 yukon denali a/c stopped blowing,at first it would only blow on low i was unable to turn it up any higher now its not blowing. do you know the problem


Could be the fan switch, the resistor, or the blower motor. A mechanic would check for voltage at each point and also the ground connection for the motor.

My 2004 gmc envoy starts but shut off after 1 or 2 seconds


Is there a Security light on the dash? Does it come on when the engine stops? If so, it could be having trouble reading the ignition key code. You would need to have that checked by a dealership.

2006 GMC Envoy I6 HVAC fan stopped working. Level 5 stopped about 6-months ago and now it doesn't work at all. I checked all fuses and the cooling fan relay but still not working.


If high speed went out first, then it is the switch.
There is the most arcing in the switch at high speed.
If there was motor or relay trouble, it would effect all speeds.
If there were problems with the ballast resistor, it would effect lower speeds.

2006 Envoy SLT air suddenly stopped blowing from vents


the resister block needs changing... oddly enough i'm unsure of what fan you are saying is not working.... if it's the front.. the resister block is located on the duct work under the dash for the air... near the fan... you will see a connector going into the side of the duct work. two screws and the block comes out... should be fairly obvious for the rear one but it will be near the fan.
