I replaced all my blend doors on my a/c unit. 2006 dodge ram diesel and it's still blowing warm air instead of cold when a/c is on.

SOURCE: air only blows on defrost (windshield)

should be electric and yes your right , the actuator .

It sounds like your electronic vent actuator has gone bad, it's common to go bad and may need to be replaced. There are tinny gears that wear out and the vent actuator stops working. You can try this, turn the radio off first so you don't have to enter the reset code to activate your radio. Disconnect the battery for 30 seconds and reconnect it, if the actuator has lost it's base line and stuck in the open heat position, this will reset it, just make sure the setting is to cold and off before disconnecting and reconnecting the battery. If this does not work, then it's a bad actuator and Auto Zone should have the part you need and will have the step by step instructions for you to the job you self, I believe the dealer is a $415,00 repair cost for this. Good luck and keep me posted.

the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to

I have the same truck with the same exact problem. Mine also stopped blowing while pulling a camper and indeed it is the clutch on the A/C. I was told if you can find someone in your area that can actually rebuild the compressor and not put a new one in you can come out alot cheaper! Also if you crank your truck and turn the A/C on look under the truck on the passenger side at the compressor and take a tool of small hammer and tap the compressor in the middle and it should come on and run the a/c for a little while! I did this until it finally went out and it worked! Might buy you some time!

I don't think they do, but you can check it will be mounted in the blower box behind the glove box if it has one.
