1982 Jeep Cherokee no heat

My son's 82 jeep full size cherokee heat control panel appears to be not functioning. When the heater is turned on you can hear the motor on but no forced air weather you select defrost, floor or panel. Wondering if it's simply the controller or something more involved?

If you can hear the motor(fan) spinning, check the linkage that controls which vents are open, also check for a vacuum leak as the vacuum hoses on a jeep that old go out frequently and many times control the switching for the heater/defrost/ac. your first thing to do will be to grab a manual for this jeep and check the actual location of the heater/vent/ac fan. there is always the chance that the fan slipped off the motor (usually doesn't happen, but the circlips have been known to fail)

have you tried it in any other position? ie: vent or ac

1997 Jeep Cherokee - Blower motor stopped working.


Check the relevant fuses with a test-light or VOM, don't just "eyeball" them as they often break at the very end. Then check the heater/A/C relays on the electrical panel. The heat/cool is controlled by a stepper motor which opens and closes the air "mixing box", but it won't work with a bad relay. If all of those check-out, you need a OBDII code reader to check the "engine" computer, as it controls the electrical modules. Also check the fusable links going to the electrical panel, and the cable from the battery to the panel. The cable may be corroded in-two and you'll never see it, so no juice to the panel, no juice to the heat/AC system. (I had a Dakota do that.) PS: Double check the grounds that they aren't corroded. Learned about that from a BSA Gold Star production racer.....

Jeep cherokee Heater blower problem


Its not the switch or the controller in the instrument cluster. On my jeep there was a panel on the passenger side under the dash board. It helped me find it by turning on the heater and going toward the sound of the blower. On the backside of the panel was a series of little coils that control the different speeds. one of those coils had been broken.

Heater fan only works on setting 4 on my jeep cherokee ltd


Hi
It sounds like the heater control panel, where the switch is attached, try to remove it from the dash so you can have a better look behind it, If all appears to be correct then the switch itself has gone.

Heated seat 1996 jeep grand cherokee


C1 & C2 in your panel are most likely one of the culprits, if no power at heater at seat. Sounds like testing for power at seat switch is easier to do than get at these circuit breakers in the panel. If you have power at switch at seat, then it's not the fuse/circuit breaker. Good reading at this link for you.
