Question about 2001 Chevrolet Blazer

1 Answer

Heater quit working

2001 Chevy Blazer when using the heater, it would literally blow you out of the vehicle. I had the stereo replaced the other day, and today was the first time I drove it in cold weather. The heater blower works but only cool or barely warm air comes out. Is it possible that something got unconnected? Should I replace the thermostat?

Some of the vacuum lines got disconnected under the dash that controls the heater box and the water control outside
