So the AC is cold on the left driver vent, but warm on the right driver vent. It's also cold on every other vent including the back.
Is this probably the mix motor or vent?

I measured with a thermometer. Every vent except the one to the immediate left of the stereo is cold.

The large driver vent to the left of the stereo is 10 degrees warmer.

Thanks for any help.
