2015 Buick Enclave - One side is cld one hot

AC blows warm/hot air. Driver’s side is cooler than passenger side but still too warm.

Maybe broken blend door actuator. Common problem.

what does it take labor hours and parts to usually repair this issue?

The place you take it to will give you an accurate estimate according to the actual repair needed . An internet guess will mean nothing .

The actuators are usually less that $50 and labor could 1/2 hour to a a few hours depending on the actuator location.

thanks so much,
