A/C and fans do not turn on, how to fix?
 

A/c and fans do not turn on in car!! Problem started on the hottest day of the year ac compressor kept turning off and then the engine started overheating. Was able to cool car down by turning off the a/c all together. A/c works on the interstate and the engine doesn't overheat, but in the city with the stopping and going causes it to overheat. The radiator overflow bowl is below the MIN level line now, no leaks. I had a leak last year but replaced flange and this resolved the leak. Checked the fuse inside panel and that is fine. Notice fans NEVER turn on even when a/c was working. Now the a/c power on the dash does not come on. Too hot outside to drive car without air so it has been sitting since Saturday night.
Need to fix asap, please help!
