02 Tribute AC Shuts Down on Highway

[budmaz3]

This started las summer. Generally poor cooling capability in general. Now AC shuts down on highway with even the slightest uphill grade. Takes forever to recover and start to get cool after leveling out or going down hill. Performance is worse at highways speeds than around town. Just had it serviced: complete freon charge and replace fill valve that was leaking. Anyone else have a similar problem? Is there a specific fix/part for this probLem?

Thanks

Did you have them check all the a/c components? And when it is blowing is it blowing hard? If not you might want to check your condesor...not sure if I'm thinking right, but I'm sure its all the same, make sure its not something restricting the air flow causing it to stop blowing...
