I have a project 2001 wj laredo that i am fixing up. Fixed the parasitic drain (broken wire in drivers door) doing the body work. It is back on the road now and I just discovered that the defrost does not work in either defrost or defrost/floor positions (the blower motor shuts off in those positions) now for the part driving me nuts the defrost works if you turn mode selector switch to the off position anyone have any thoughts or have had this problem before I have no codes or any other problems
So you have the AZC system in your jeep. When you select the mode selector in off, the blower starts working and the air comes out at the windshield?
I have the normal (basic) 3 knob system 1st knob fan 2nd temp and 3rd mode. and yes in the off mode position the blower works out of the windshield (defrost vents) in the defrost/floor and defrost positions the blower shuts off all other positions are normal Thanks
There must be something wrong in the AC control panel. There is some sort of switch on the mode knob, which is in series with the fan mode selector. Maybe by removing the panel that you can see this switch. Don't know if its possible that it is loose or misadjusted.
