My 99 Dakota R/T and 99 Durango have no heat blowing to the floor. Fan is running and every other setting blows where it should. Heat is hot.
My 98 R/T blows to the floor.
Any help????

There is a vacuum diaphram above the gas pedal that has two lines running into it. One line sends air to the dash, the other sends air to the floor(I think). You may have a line off of the floor side or the arm of the diaphram may be disconnected altogether. This may not be the fix, but this is where you should start looking. Hope that helps.
