I am having the same problem.. I have already had to replace the intake manifold gasket cause it was leaking, still no heat. We will be flushing out the heater core to see if that's the problem. I may have to replace the heater core, we will see.
Is it blowing cold air only or not blowing any air at all.
It may have a bad heater core.
my Chevy blazer power seat on my 1996 Chevy blazer isn't working
You have a short in the wiring or at one of the bulb assemblies.
There seems to be a short to ground in the wiring somewhere.
It being an American vehicle
NO.. It will not.
check ground first
The fuel pump is shorting out and that is why the ecm fuse is blowing .Disconnect the the fuel pump and try it again,if the fuse blow's again then it is not the fuel pump.
The Blazer was discontinued from production after the 2005 model year, and was replaced by the TrailBlazer. That being said, you have a short to ground somewhere in the circuit.
Beause there is probably a short/bad connection in the switch, or the blower motor itself
My 2001 Chevy Blazer was blowing cold air when I had the heat on. My husband flushed the line to the heater core and a bunch of junk came out and now my heat works great.
