Try changing your control panel i have a 1997 Chevy K1500 did that and solve it. I f you dont want to pay for nothing go to a scrapyard ask him a unit and try it there on my model was quite easy to change. So if its working you pay for the parts if not you just give him back.

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

Water leaks on the passenger side carpet when i run the air for an extented time on my 04 gmc envoy


The evaporator for the air conditioning is under the dash on the passenger side. Open the hood and look on the firewall for a rubber hose that sticks out of the firewall. This hose is to allow the water to run outside and onto the ground. Sometimes they plug up and the water can't get out so it builds up and drains onto the floorboard. Hope this helps...
