The temp blend door is located behind the dash assembly in the HVAC assembly. Unfortunately the entire dash assembly needs to be removed to gain access.
195-210
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
Factory said to use a 195 degree thermostat
It should have a 195 degree thermostat.
The temp blend door actuator is probably at fault.
A bad engine temp sensor can do that.
Yes it sure can.
It is up by the thermostat housing on the front of the engine.
Neither, I believe it's electric.
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
It is located behind the grill but in front of the radiator on the passengers side of the vehicle.
Drivers side under hood between the rear 2 plugs - see the connector attached to it. You will lose coolant when removed so make sure you refill.
