The dealership added Freon to mine under warranty. No difference - the passenger side is still 5-8 degrees warmer than the driver side.
anyone find a solution for the passenger side AC problem?

ORRR...... OR, maybe she'll allow a very sweaty FatJack to ride the passenger side for theory testing purposes. I am certain she WON'T say no.

I was doing some research and this is what I found
Up to 12 degrees difference in temperature from side to side is normal. If the difference in temperature is greater than 12 degrees, pinch off a heater hose for a test. This will help you determine if you have a blend door problem or an A/C performance problem.
If you are dealing with a DR that has cold air blowing out of the left side vents but warm air blowing out of the right side vents, verify the charge in the A/C system. The flow through the evaporator is from left to right. If it is low on R134A the right side will be warm while the left side is nice and cold. The label for the charge under the hood shows that the system should be charged with 1 lb 10 oz. Frequently technicians have been mistakenly taking this for 1.1 lbs when it is actually 1.625 lbs or 26 oz.
An Example:
Sticker on gas truck shows that the refrigerant should be 1 lbs 10 oz. Technicians are looking at this quickly and seeing 1.10 lbs. On a diesel truck it shows 1 lbs 14 oz. Technicians are adding 1.14 lbs.
Gas 1 lbs 10 oz (1.625 lbs) NOT 1.10 LBS.
Diesel 1 lbs 14 oz (1.875 lbs) NOT 1.14 LBS.

Hey, thanks for this info. Now I am going to go outside and stick a thermometer in each vent and make sure that it is really still having an issue. The dealer added Freon, but the "hand test" says that the passenger side is warmer. I'll put gauge on and see, just out of curiosity.

My truck used to have this problem when I got it. What I did is recovered all the refrigerant and left the system in under a vacuum for an hour. This will remove anymoisture in the system. Then recharged it back with .2oz more. The A/C blows @37 on the drivers side and 40 pass side. That works out just fine since the girl usually always fkn cold.
Most dealerships skip putting the system under a vacuum for 30 mins like they should. Usually only do it for like 5 mins
