Best Answer

I just asked the local dealership and they said that there is no heater conrol valve on a the blazer. I'm having problems with my heat where it blows hot air for a short period of time and then it would quit, I was told to get the system flushed and that should take of it.

control valveyou can install one yourself on the hoses leading to the core, they can be purchased from a local parts store or simply loop the two hoses together to bypass the core. Many people extend the life of their heater core by bypassing it during the summer months to avoid unnecessary corrosion or, or bypass it if it begins to leak.
