Heater Airbound? Heater control cable not working? Heater core plugged?
Low coolant? Bad thermostat? Heater core plugged,restricted, or air bound? Water pump not circulating coolant? Heater control cable not adjusted properly?
Neither, I believe it's electric.
The most likely reason that the heater control won't change the air flow is that the cable that moves the diverter valve has broken and will need to be replaced.
The 1997 Chevy Blazer shifter cable will have swivel nuts on each end of the cable. Connect the shifter cable and turn the swivel nuts to the right to install the shifter cable.
I believe that the first digital cluster on a S-10 Blazer was in 1989.
Remove the radio/heater control module. Disconnect the temperature control cable at the base of the control assembly . It is on the center mound just to the right of the gas pedal. Take the heater control cable off of the back of the heater control module. Pull the temperature control cable off.
The 1996 Chevrolet Blazer shifting cable will have a retaining nut on each end of the cable. Loosen the retaining nuts. Remove the cable routing retainers. Reverse the process to install the new cable.
disconnect your neg batt cable
If you are refering to the Hot/Cold knob on the inside of the car on the AC/Heater,,,,yes,,, that is the only knob operated by a cable the rest of them are either vacuum or electric
Replace it with a new one, there is no repairing it.
About 30 min.
The heater valve is in line in the heater hose from the top back of the 350 engine about half way to where it enters the firewall to connect to the heater core. The valve has a steel wire control cable connected to the top of the valve control lever. It has two hose connections, one in from the engine and one out to the firewall core entry point. Trace your heater hoses and look for the metal valve with the spiral covered control wire.
Low coolant? Thermostat not closing allowing engine temperature to rise? Plugged heater core? Air bound heater core? Water pump not circulating coolant? Heater control cable not adjusted properly? Bad selector switch?
It is attached to the starter. The positive battery cable runs directly to it.
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced
Remove the positive battery cable from your 1997 Chevy Blazer battery. Remove the cables from the front of your starter. Remove the starter retaining bolts. Reverse the process to install the new starter.
usually on the rear lower end of engine--follow + battery cable
Should be on top of the starter - follow the + battery cable
Disconnect the negative battery cable from the battery.
This might be a cable for some additional feature your car is not equipped with, but the wire is included in the standard cable assy
No cable, all controls are done with electric motors.
Rebuild the rear drums. Or maybe yank on the cable under the body.
