Question about 2004 GMC Envoy
This morning I tried to turn on my truck and is was completely dead. I replaced the battery and noticed that even with the engine off and the key removed the air continued to run inside the truck.

SOURCE: 2005 GMC Sierra Overheating
If your sure there is no trapped air in system after refill and air bleed off, is fan clutch pulling good air thru radiator? Even if it is, the heater should have coolant as hot as what temp gage is showing! Try backwards flushing heater core (dex cool is notorious for plugging these up). There is a TSB for cracked cylinder heads from GM for unexplained coolant loss.Remove drivers side valve cover, and look at center three head bolts for coolant around them, if coolant has been getting in thru this suspect area, there will be a milky/pudding like goo under valve cover and on head. GM had a company called Castec cast these and the areas near the head bolts were found to be too porous (NO recall YET!) Ya, you guessed it, replace heads! Unfortunately, if its gotten hot to many times, it has probably hurt the heads/gaskets. Hope this helps. PS: The castec logo is under the rearmost pair of rocker arms,may have to remove them to see.

Black box (plastic) usually pretty handy to battery, you should see red (usually) cable from battery running to it. Another thing that came to mind, you don't have anti-theft system on that do you? Sometimes they will cause problems after a dead battery. Try using your key & valet key to unlock the doors, manually especially drivers.

I have the same problem on my '07 gmc 2500. I understand there is a problem with the "cannister filter for emission control of fumes from gas tank" (or something like that). Apparently, it is located near the gas tank which causes it to plug up easily from road dust. The fix is to relocate it with long hoses into the engine compartment area. Since the filter alone is $250 (or so I've been told) with labor it's a $350-400 fix. Supposedly, there is no damage that can be done so I'm just tooling along without worrying about it until I have to put the truck in the shop for something else. Seems there ought to be a recall for this, by government motors won't come out with it.
