i have a 98 jimmy . for some reason my heater will not blow air on the floor setting any more . vent and defrost settings work fine but when i switch to floor it pauses for a second and just blows from the defrost . any idea where i should start looking for the problem ?

 

never mind , found this post online http://www.s10forum.com/forum/f136/n...blazer-314010/ and figured out the door in my heat box was broken like most others . i used the coat hanger method described in the post to get the heat to blow out of both the defrost and the floor . i have no intention of taking the dash out so it will have to do ..
