hey

i have a 97 explorer sport...noticed that im getting hot air out of the vents on all settings except max AC....i had it at a garage not the dealer, and it stumped them...they said there is a part, forget the name, with a door that swings back/forth to allow the cold/hot air through, the door will swing normally when its taken out but put it back in and u have the same problem...any thoughts? please reply to my email at wldthng99(No Email Addresses In Posts!) thanx
