Is there something wrong with the a/c? Or is it just the heat from my giant untinted windows just so strong it makes it seem that way?
I have a '10 Chevy Aveo. And it
seems that the a/c loses power (not
as cold, maybe not blowing as
strong) the longer I drive. Obviously
this problem is only noticed on road
trips, so after an hour or so.
hard to say..might just need a lb of freon...
If you have system checked out and everything is good have the inline filter checked it maybe partially clogged this filter is in the inside high side line of the A/C system.
Looks like you'll need some refrigerant..
This is assuming that the system is fully charged. It could be icing up, next time try just turning it off for a few minutes then back on, if it helps then it is possible that the cycling switch is either set too low or is on it's way out.
You also may want to spray out the A/C condenser coil and radiator and see if it helps with a garden hose and nozzle because if the fins of the one that is in front of the other maybe be partially clogged with dirt and bugs restricting air flow across the fins of the A/C condenser coil especially if condenser sets in front of radiator.
