Im having heat issues with my 2002 Grand caravan. I have heat when the van warms up but after about 20mins it starts blowing cool air no matter what the digital readout says. I have the Automatic Climate control. It does the same thing in Auto as in Manual. Any help would be greatly appreciated.
could be a blend door problem
do you have the heat set to high?
it also sounds like a classic t-stat gone bad. what does your temp guage do? make sure you watch it closely because they have resistors on them so that they will move very little but you should still be able to detect enough movement to see if the stat is working.
because it starts out hot I am leading to the t-stat and not the blend door.
