Question about 2000 GMC Jimmy
My 2000 GMC heater will not heat the car. I had the radiator flushed and new fluids put in this week but still no heat. Is this a common problems?
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.

Try removing the heater hoses from the waterpump and the intake mainfold. Then use a compressor to blow out the gunk in the heater core (place the air hose into the the hose you took off the water pump). This worked for my 2001 jimmy.
