CHEVY PART NAME

1995 Chevrolet Tahoe

Heater problem
1995 Chevy Tahoe V8 Four Wheel Drive Automatic 162000 miles

I am trying to diagnose why I have no heat. I found that the heater control valve that lets coolant go to and thru the heater core is not opening. I need to know what the part is that sends vacuum to the valve. This part is located on the accumulator. It has a 2 wire connector going to it and one vacuum line coming out of it that goes to the heater control valve. Thanks in advance.

Hello,

I believe it is either a Vacuum Selenoid, Vacuum Pump or a Vacuum Switch.

Have you tested for power to the part in question.
