No Heat but blower works
Hi All,
My daughter's 99' Blazer is not producing heat for the heater or defroster. The blower fan works and the mode selector switch seems to work as well. What should I check for and how would I fix it. Thanks for the help.

No heat
Hi,
I am having the same problem with my 99 blazer. Both heater lines remain cool with the engine warm. Blower works too. Seems as though I have a restricted heater core. How do I resolve this? I hope I don't have to get to the heater core as that seems like a project, removing the dash and all.
Thanks,
Larry

I had a problem with my jimmy a couple of years ago,same symptoms as yours. I put a flush adapter on a heater hose didn,t work. so i held a garden hose on the heater core fitting ,and a big blob of slime came out of it, it has worked great ever since.

Well, my daughter came home long enough so I could work on her vehicle. It turns out it was about 1/2-2/3 gallon short of radiator fluid. Topped it off and it works fine now. Seriously considering flushing the system any way to be on the safe side.
