I was wondering if Anyone can help me at all i love this jeep too much to get annoyed over somthign that can be so small:bawl: pleas help thanks very much :wave1:

welcome!! go look behind your front bumper (I know, it sounds like a stupid place to look) for a plastic football shaped vacuum canister. It holds the vacuum that opperates your HVAC controls. Inspect the lines to and from it for a break. You'll probably find that under the battery one of them has corroded and therefore not supplying vacuum for the controls to opperate (the default is defrost for safety reasons). Fix the line and see how she works then.

i have the same problem in my 99

the football shaped thing you are talking about is compleatly missing

when i replace this do you thing it will fix the problem right away?

replace the canister (fairly cheap at a salvage yard) and follow vacuum diagram in FSM to ensure correct routing of hoses. Chances are, it will work afterwards. If not, you could still have a bad diaphragm under the dash (the thing that actually moves the door that directs the air) but that's less likely-- especially since you're missing the canister!
