Help pls - Strange A/C problem

[weifert]

A/C acting strange on my 11 Tahoe. I turn it on, and the front dash vents - warm air blows out on the two drivers side vents and cold air blows out the two passenger vents.

Any ideas?

Thx.

Its one of the blend doors in the or actuators. How many miles do you have? Hopefully its under warranty because its a PITA! Good luck!

In dual zone sys, you will have a 2 section blend box behind/under glove box. The actuator for the driver side should be the lower on. They cost about $130, and are easy to replace, just can have access issues. The lower one is easier though. BTW you have actuators for mode, recirc and also for rear system. So they can and will go at some time down the road. The recirc one sucks, under the dash.

Ive been having the issues for about 2 weeks now. I saw the other posts about actuators - suggesting i replace that. Do you have any other details on how many actuators there are, which one to repace and how to do that?

Thx

Hello Bill,

I apologize that you have been experiencing these A/C issues for two weeks. Unfortunately, we are neither technicians nor engineers so I am unable to provide you with any technical assistance. If you would like, I could set you up an appointment with a dealership for a diagnosis. Please private message me if that is the route you would like to pursue. Thank you very much for your time.
