It is connected to a door in the lower part of the heating box. It is connected to a lever about even with the accelerator pedal on the tunnel housing under the HVAC controls. Check that the cable hasn't slipped out of the arm.
under the glove box is the lever the cable goes to. move it by hand and heat will be on. or replace the cable.
thermosat could be stuck open or low coolant or heat control cable could be broken
Low coolant? Defective thermostat? Heat control cable not adjusted properly? Heater core plugged or airbound?
There is one cable from the pull handle thru the floor. That cable connects to two cables that travel to each rear wheel. This one to two junction is uder a heat shield on top of the muffler. Not the easiest place to get to. Had to change the two cables today. They get stuck.
Air bag module is right in the midle of center console under neath the AC/Heat control, if you pull AC/Heat control , you will find thick yellow cable socket that is connected to it.
Well on mine , I discovered that the thermostat had actually fell apart and was letting the water go passed too fast to heat up, so check there first. The problem I found on mine was the heat temp control cable. The plastic tab under the dash that moved the flapper to control how much hot air came into the interior was broken at the cable end. With much patience and scratched arms I reattached the cable.
low coolant? Bad thermostat? heater core airbound? control cable not adjusted properly?
No , if you were to bypass the heater core , you would have no heat
Low coolant? Bad thermostat. Heater control cable most likely to be blocked heater core if blowing cold air! back flush heater pipes if this doesn't work heater core is a bad job to replace. dash out!
Check coolant level? Bad thermostat? Heater core airbound? Temperature control cable not adjusted properly?
Could be: Low coolant level Bad thermostat Heater control valve/cable not adjusted properly
The resistors that I know of are behind the control for the heat and A/C. I had an issue with no heat and not blowing air until level 4. I replaced the module and everything works fine.
