2017 Tahoe A/C works after 2.5 hrs of driving.

A/C doesn’t work.
It slowly got worse over a year time.
Figured it had a leak and needs a charge. But wife drove it on a 2.5 hr trip and by the 2.3 hr mark it got cold.

Is there some thing clogged? Besides the front condenser which is clear.

Probably needs refrigerant again. Get a manifold on it and see.

Thanks for the reply. I am ordering one now. Plus the pump and temp sensor and thermometer.
