Passenger side blowing cold air

[LTZboy]

Has anyone else had this problem with heat not blowing out of the passenger side even when set to 90? I have been to the dealer 5 times now as of today. I even have changed dealers. They have relearned all the blender doors 4 times and today they replaced the entire control board and still tonight blowing cold air. The drivers side has been blowing the correct temperature the whole time.

I don't see anyone else with the same problems.

Anything the dealer should still check?

My cousin had the same problem with his silverado but it was HOT air and it was on the drivers side. I'll check with him.

It could be the actuator.

Well I have another appointment with the second dealer tomorrow, so maybe they can fix it on the second try. It wouldn't be such an issue if it wasn't in the 20's and it blowing cold air for my passengers, LOL

I have the same problem with my 2000 Tahoe. IF you find out what it is I would love to know. I replaced the filter and even tapped shut the recycle vent. Mine is like there is a whole in the dash letting in cold air.
