2004 Yukon Denali. Drivers side and defrosters blow cold while passenger side is hot. Went to dealership and they are claiming truck has 3 actuators and ALL need replacing to the tune of $1600.00. Looking to locate drivers side actuator in order to try and replace myself. I thought it was under drivers side dash. If it is located on passenger side as in you Chevrolet video I'll just try swapping that one for a new one. Any help would be appreciated.

Thanks

Hello,

The driver side blend door actuator is located behind the center console.

Keep in mind that after replacement the new actuator will need re-learning procedure in order for this to work properly.

I have attached the replacement and the re-learning procedure below.

Please let me know of any questions.
Thank you.
