A/C blowing cold drivers side & warm passenger side - Diesel Forum

This has been going on for some time now. I took it in to the dealer this week and they replaced the A/C control module. They obviously did not drive it as it still starts off cold on both sides and then as you are driving the passenger side starts getting warmer and warmer. This is on single or dual A/C. I had both sides on 68 degrees and the right side was blowing warm air. You have to put the right side on 60 degrees to make it blow cold air. This aint right. I'm taking it back in on Monday. Called them today and told them to get their eads together. I think it is the dampers/gates or whatever lets in warm air to maintain the setting you select. Anybody got any ideas?

I took it back this morning and they finally figured out that it is the actuator for the dampers/louvers or whatever they are called. No one in the Houston area has one so they had to order it from Ford. Should have it in in several days. Hope this fixes it.

Mine has been doing this for several weeks now. I dropped it off today for the repair and I expect them to tell me it is the driver side actuator, or whatever it is called. I've read it is a 5.5 hour dash tearout job...

I wasn't counting on it being backordered... There sure have been allot of guys having problems with these. My buddies 08 F150 had a similiar issue.

I finally took my truck in for this issue. The service guy acted like this was common, which I believe it is. They replaced the right side temp blend door actuator, which he said did not involve tearing out the dash. They also referenced a TSB, which I don't know what the specifics of that are. The service guy said this was a motor which sits either on top of or below the blend door. This motor is what turns the blend door.

My ticket reads:
Pass AC going to hot a times while drivers side stays cold
Verify concern. Check Oasis and locate TSB 09-12-15. Replace right side temp blend door actuator per TSB. The part number is listed as 1 9C3Z*19E616*B Motor Asy

So far, so good...
