Temp control problem

[Chevrolet1698]

My ‘04 Silverado only wants to blow heat on the passenger side, yet I have both temps set to max heat. On the driver’s side it blows cold. It is a WT trim with manaul dual temp controls. I am not an expert at climate control systems, but is it a bad sensor/actuator that’s not picking up the driver temp or something?

It is and luckily for you it is the easy one to replace.

Actuator you need.

Video on how to replace. I know it says escalde but it is the same repair.

this blend door actuator, are there 2 of them (driver/pass side) for dual climate control, with the PS being the hardest of the 2 to get at? I had the same problem but the PS was blowing heat on the coldest AC setting. The dealer repaired it upon my purchase but the tech made mention it was a real PIA trying to reach it.
