I had problems with a similar truck,a 1998 GMC diesel after checking to make sure the control cables were operating the blend door and blowing the mess of the heater core,I replace the thermostats.Still no heat turns out there was a small amount of debris collecting in the fitting for the inlet hose at the thermostat housing after removing it and blowing out the lines the heat was fine.

SOURCE: Replacing heater core in 2000 GMC sonoma. Dash is

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

SOURCE: How do you remove a heater core from a 2000 GMC

2000 GMC Jimmy heater core replacement in order to replace a heater core in a 2000 gmc jimmy the coolant must be completely drained and the entire dash including radio, vents and panel covers must be removed. four screws hold the top portion(closest to the windshield) in place. they can be found under the windshield defrost vent. after the entire dash is removed a safety harness under the steering column must be removed and the steering column must be dropped to the driver seat. the heater core housing(black plastic) is located right center of the dash and is a two part housing one piece on top of the other. the housing is attached to the fire wall and must detached before replacement can continue. after detaching the housing from the fire wall separate the housing by unscrewing the six screws that hold it together. the heater core is now exposed. disconnect the heater core from the two hoses and discard. installation is the uninstall process in reverse. it is a very long and drawn out process that is not accomplished in just an hour or two . make sure you have most of the day or several afternoons to finish . Good luck and take pictures with your cell phone to use as reference.

My 94 gmc jimmy is having a little problem that idk how to fix...the radiator fluid is somehow leaking into the floor of the passenger side and it seems to be coming out of the floor heater vents...if...


The idle could be a few things dirty air filter or fuel filter i would check these first you don't mention any engine codes so its likely a minor problem . The antifreeze leaking inside is comeing from the heater code eighter you should check the heater hoses that connect to the core to make sure its not leaking at the nipple but you have a 94 so it may be the core it self has a hole rotted in it or poped a solider joint. How dose the heat work in the vehicle is it ok or blowing cool or cold air . this will tell you a lot because clogged heater cores tend to rot out where if you have good heat then it maybe a minor leak at the hoses good luck with it

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

My heater is not working.


You need to check your Heater core, It may still flow but if it pluged up inside it will not work right (little heat) If you smell antifreeze inside your car it's a sign it could be whats wrong.

No heating on jimmy....fans blows cold air only....heater core is fine


Mine did the same thing you need to have heater core flushed out. Dexcool coolant clogs it up get it and the radiator back flushed and changed to regular coolant. This should fix the problem.
