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
