Air Conditioning problem
2003 Chevy Tahoe V8 Two Wheel Drive Automatic 112,00 miles
----------------------------------------------------------------
A/C in front will not cool and doesn't blow as hard. The back A/C blows good and is cool but not as cold as before.

Recharged with more freon but less than a week, back to not cooling again.

Is this a leak or something else?

did you vacuum the system before recharging? this is probably why not good cooling but you probably do have a leak. the low air flow from the front tells me the leak could be the evaporator core thats why the flow of air has slowed, due to partially plugged from leaking.
