When hot outside, AC starts out working. Then (5 min) temp gauge goes from 1/2 to 3/4 and AC starts blowing hot air. After a while temp gauge goes back down and AC works for a while again. Then same thing happens again. Local auto repair shop has tried to find problem but has been unsuccessful so far. They are going to replace a heat sensor today. At one point last year they thought the electronic fan was quitting which allowed the temp to go up so that AC was switched off. Nothing confirmed.
