Wierd Problem
I have a 03 Ram with 185,000 miles and my problem started a few months ago. When running the AC, the air on the drivers side ventsis cold and the air on the passanger side was just cool.I decided to try the heat and see if it did the same thing and it is opposite. The drivers sides vents blow cool air and the passanger side blows warm air.Any ideas what the problem is?
Thanks in advance

Your temp doors are controled by vacuum. Sounds as if there's a line disconnected or broken, or a vacuum control podwent bad. (or stuck door)
You'll have to lay on the floor and check under the dash to make sure things are hooked up. Not sure if there's a junction off the back of the control unit or not, but that's suspect as well, if there is.
Suspect the passenger side, as it blows hot air, with A/C on. Sounds like the temp door is failing to close, allowing only cold, A/C air to flow through.

Somebody on here had this, I think it was a mixing door stuck. Turned out to be quite common.

I have been pleased too.I bought the truck new and all I have had to do to the truckis change the TPS. Believe it or not, I put the first replacement spark plugs in it at 175k and it was running fine then.
Thanks for the help!
