Defroster does not blow when it's on defrost it blows out of air vents. If you put it on floor it blows floors and air vents with heat or air on and passenger side is a little warmer. When you have air on and I run the codes, 1263, 2426 and 2796.
Do you
have the same problem?

Good morning,

The actuator is most likely the issue. The codes are for the defroster actuator.

I attached a picture of the actuator and how it mounts. The down side is the dash has to be moved back to access the motor itself.

Based on your input and the codes you gave us indicate the actuator for defrost control is not working.
