So.. I have heard of the 3rd gens blowing colder on the drivers side than the pass. side. But in my truck, for some reason, it is a really big difference in temps. Driver's side blows super super cold, and passenger side is just slightly cooler than the outside air. Some kind of door stuck? Not an a/c person by any means and don't really know much beyond the basics of how it works. Any input?

 

This topic actually came up the other day on forum. Give me second and I'll see if I can find it for you.

 

More than likely your recirculation doors are not working properly. My friend here at the dealership makes a GOOD living off of replacing those things all the time. My truck is currently doing the same thing AGAIN for the 3rd time and every time its those stupid recirculation doors that are causing the problem.

 

Here is a good thread. 03 ac not working on pass side!

 

Read away fellers.....been there done that!!!!!! and it is over.
