Blows cold on driver side, but hot on the passenger side and in the rear. Did a HVAC computer re-calibration and looked for any obvious damage to visible ducts. Checked fuses and they all looked good.

Good afternoon.

It sounds like the blend door motor is not changing to AC mode. Very common failure.

Can you hear the blend door working when you command heat and cold from the dash?

The blend door is inside the dash and the instrument panel must be removed to gain access.

Are you planning on doing this repair yourself?

It was the blend door. I finally found a video which had the exact same issue. I manually turned the actuator for a temporary fix. I am planning on replacing the blend door actuator. Now on to the ABS Light. I heard that it commonly could be a dirty speed sensor. Any thoughts?

Okay,

Are there any cods for the ABS?

Dirty sensors, no, bad sensors, yes.

The code will lead us in the direction of failure.
