Ricky,
Both your A/C condensor and you Injen intercooler (I'm assuming that's a front mounted intercooler) are placed in front of your radiator.  If the fins of the intercooler and condensor are clogged with dirt and debris, your radiator will inefficiently be able to cool your engine and will cause it overheat.  You should also be sure you have a sufficient amount of coolant and that it's the proper 50/50 mixture.  Replacing your thermostat and radiator cap may also help.  Verify your radiator and AC fans are coming on as well when engine temperature rises above normal.

Your AC system has a leak in it.  The most common area where it leaks is in the condensor in front of the radiator (as mentioned above).  If you drive in an area where they salt the roads in the winter, salt build up can corrode parts of the condensor and cause it to leak.  You should also check your intercooler to see if it's rubbing up against the condensor and may have caused a small hole.  Even the smallest hole can cause all the freon to leak out within a day.

There may be a simple wiring problem with your wipers.  Other than doubling (or maybe triple) checking your fuse box wiring may reveal the problem. You may also have the problem in the multiswitch on the steering column.  That's not easy to diagnosis, but at least you know the wiper motor works.
Good luck!
