No Ac In Front Rear Good Heat Wave

[CIECO]

OK, in the middle of what I hope is the last heat wave, I have no front ac, only warm air. I have a 2003 Yukon XL 2500 with a 6.0 engine, dual climate control in the front.

The rear ac is cool,and the low side tube in the front is cool. when i turn my climate control up to 90, it gets very hot but when i turn it down to 60 it never really gets cold. Let me know if you have any ideas of how i might be able to fix this. Thank you.

Ive got a 2003 yukon as well. Same thing happened to me last summer. They replaced the control panel - which fixed it.
