SOURCE: Heater/AC only blowing out of defroster vents

Defrost is the default. Pull the heater control panel off and make sure the vacuum lines are connected to the control. My Jeep had the same problem cause I was messing with the radio. Hope this helps.

SOURCE: Heater problems on my 2000 Jeep Grand Cherokee. Please Help!!

THis is a know problem with Jeep GC. If only one side is cold and the other is hot and there are no controls error codes. It is likely a broken temperature blend door on the faulty side (w/ dual controls). Dealer charges a lot to fix ~$800. There is a kit and instructions sold on EBAY to replace the part for $100. Seller claims that a relative novice can fix w/o removing the entire dash board as the dealer does. Has sold hundreds of kits....people seem satisfied....you may check it out. Search Heater Blend Door Jeep on ebay. Replacement parts are aluminum instead of OEM plastic.

Self Diagnostics on HVAC system. Jeep GC has built in diagnostics and will return error codes on the temp display if it is otherwise. Simple to display.
1) Press A/C and Recir button simutaneously
2) Rotate driver temp control knob clockwise then release buttons
3) If no controls error a code of "0" or "00" will be returned.
4) Error codes listings can be found on-line if anything but zero

Dealers charge $45 to run the same check

SOURCE: 2001 Jeep Cherokee a/c blows defroster only, no cruise control

There is a vacuum leak under the hood somewhere. Check the vacuum at the speed control servo. If there is no vacuum on the line with the engine running, follow the line to find the leak. The vacuum reservoir is mounted under the battery tray. I would look in that area after confirming no vacuum at the servo.

SOURCE: Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

SOURCE: heater only blowing out defrost vents

Open your hood and find a "T" connector right near the battery. Follow the line down below the battery (you will have to get under the Jeep). You will see that the line plugs into a 3 to 4 inch section of 3/16" tubing that is plugged onto a black in color, plastic box. Use a razor knife and trim off about 1/2" of this 3/16" tubing as it commonly cracks where it fits on the nipple of the black plastic box. The vacuum cannot build pressure properly with these cracks in this tubing, and therefore cause the selector door to malfunction when operating heat and a/c. It is a quick and easy five minute fix.

1996 Montero Heater Blower not working


I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.
