When I turn my heat on one side blows cold and the other hot. Dual climate not on. Anyone know how I can fix it.

Which side blows cold? You may have a bad vacuum actuator! They are vacuum controlled through the programmer, and you could also have a restriction in the manifold (connections) to the vacuum actuators. Have you got a good vacuum to the black line going to the programmer?

Passenger side blows cold air, driver side heat

 

[HotZ28]

Evidently, you have a bad actuator, or restriction in the vacuum supply to the actuator! Check the vacuum to the actuator from outside air inlet.

I took the glove box out and the actuator switches when you change temp and vent modes. I’m gonna check the vacuum tomorrow. Thanks.
