Hello! First of all you have an air "bubble" blocking your thermostat...If you have a garage and can get the vehicle inside let it cool so you can open the cap...Start the engine...Turn the heat on high...As the engine warms air will bubble out of the top of the reservoir ...When the thermostat opens...Slowly add 50/50 until all air has escaped...Don't be in a hurry, wait until all air has stopped and system is full...To be on the safe side you may want to replace the thermostat before you begin this procedure...

In the under-hood fuse box...Try pulling the ABS fuse (60A)...Test drive the vehicle to see if it will perform braking wise until you can fix ABS...Send a comment and let me know how you make out...

My 2000 jimmy has heat problems. the heat goes from cold to hot to warm to cold etc. what could the problem be?


If the temp gauge is now more stable, the problem is in your heater system, not the engine cooling system.

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.

2000 GMC Heater Problem


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.
