Mine is much cooler, although I don't know the actual temp. You should have the dealer or an AC shop check the system out. You may be low on R134A or perhaps have a blend door issue. You should also check the cycle times of the compressor. If it clicks on, then clicks off, then back on in quick cycles you are probably low on coolant (freon). In which case you have a leak. Some times the clutches go out on the compressors as well....just so many things in an AC system that can cause this. Its best to just have them look at it.

Also, don't ever add Freon yourself....it really needs to be done properly with a machine. You can damage the system.
