Default Went on 1.5 hour roadtrip today, AC felt much weaker and less cool on the highway

doing about 70+ mph. The blowing air wasn't coming as fast as it normally does. When I got back down to normal highway/road speeds, it seemed like normal. What's the deal?

sounds like you may need to add some freon. or maybe check for some leaks. also at WOT it automatically kicks of the A/C from what i hear if thats what you mean.

Yeah, add some Freon. . . Great idea.

Check your vent temperature.

It should not be higher than 60 degrees Fahrenheit.

If not, check your high side and low side pressure. . . .OR TAKE IT TO A SHOP IF THIS SOUNDS TOO FOREIGN. Don't mess with your AC system unless you have a fairly good idea of what you are doing.

Well, I added some refrigerant awhile back. I could tell that it did get a little cooler, but it took awhile to add, which makes me think it didn't really need any.
