problem with a 99 dodge ram AC?
I have a 99 dodge ram Diesel when I turn on the the AC it blow out cold air for 5-10 seconds, Then I can hear a door close in the dash and hot air come out. I tried to find where this door is with no luck. Do you know of a way to hold this door open to keep the cool air on

You are hearing the temp blend air door. It thinks you are asking for warmer air by mistake. Not your mistake. You may take the glove box out to see something. It's quick and inexpensive. Other than that it is computer controlled, checked and reset. If you can see the little motor that moves the door try unplugging it when it is good. Try unplugging the BCM computer behind the right panel where a passenger would kick if moving their foot to the right while sitting. Wait a few minutes and plug it back in. Try it with the key on and controls on, and key off and controls off or combos.
It needs a computer that the dealership has to fix it quickly and cheaply. best of luck
