Power outages in hot weather

When the temperature reaches over 80 degrees outside my A/C, power windows and dashboard gauges stop working. All the fuses are good, and electrical works fine until the air temp gets hot. HELP!

Hi, As a test switch off the A/C just before the 80 deg. temp is reached and see if the power windows and gauges still work when the temp increases. It may be that the A/C has to work too hard to keep the temp down once it gets too hot. Basically trying to see if the A/C is the problem or not.
