guess what? another a/c question

[yukonfan]

2004 yukon with dual cc. Im having an issue where 20-30 min into my drive my ac starts blowing hot air on the driver side. If I turn my truck off and right back on then boom.... all cold again. What should I be checking? Thanks folks

Driver side temperature actuator. The system can be scanned. Just a guess from here. Never hurts to make sure The pressures look good.

Seems like every time we turn around we see another need for a member to own a Tech 2.
