It could be anything from a broken blend air door shaft, a blend air motor that isn't working, the control head may be burnt out. A scan tool to see the inputs and outputs of everything may be needed to verify and to retrieve any fault codes stored

I have a 96 Grand Caravan 3.3 liter v6 with exactly the same problem. I did the code check without reader

but nothing showed up. Maybea reader checks more? I can hear a motor/acuater trying to dosomething when I operate passenger side heat control. I started todisasemble dash but decided to do a little more research and possiblybuy a repair manual. Dealer does not stock the blend door shaft ifthat's what it is. The passenger side blend door actuater seems to beon right side, but I'm not sure. If I have to pay $950 to repair theheater on a $3,000 van I'll dump it and get something more reliable. I have a few other electrical problems, intermitent left turn signal,rear wiper will sometimes start on it's own, small agrivations, butsince I'm thinking of driving north this winter the heat issue isserious. Already put $600 out for a transmission seal on a tranny thathad just been rebuilt by previous owner. I really miss my 93 Voyager 4cyl 5 spd, good milage no problems except axel seals. A old Ford vanpulled in front of me and it was totaled.
