No heat on driver side

[Stlram81]

2011 1500, dual zone climate. Only getting heat on passengers side. I have went through all the different settings, diffrent combinations of settings and nothing.

Maybe a stuck baffle?

Anyone else see this issue?

You are probably in luck, the left temp actuator is most likely your problem. The right would require a trip to the dealer.

Is that hard to get to? I'm assuming the dash will have to come apart?

Not to hard, remove the glove box and it will be near to the radio.

Checked the three actuators i could get to. Removed drive and moved door by hand. Assuming one was stuck because I now have some heat on the drivers side. Not quite as hot as the passengers side but way better than it was. Thanks again for the help

Well. It worked until I had to use the defrost this morning. Picked up an actuator, going to try that.

Same issue, but mine is not dual climate. Not very hot, but warm air on passenger side, but none on driver side. Checked all actuators that I could find (3. 2 in the center behind the radio, and one in glove box), and all seem to be working. Flushed the heater core, added some coolant to the truck, and still only on the one side. Am I missing anything?
