A/C blows hot air but will blow ice cold under some circumstances
My A/C blows hot air but will blow cold if the ABS system is engaged or if the brake is depressed suddenly/hard. This "activates" the Cold air and I will get cold A/C for 3-4 min. Eventually it will go back to warm/hot air again until I go through this same scenario. I have had Freon added to the system and its pressured up as well as having a new O-ring. Prior to the "brake" activation trick, it worked if I turned it off and back on or if I turned the high/low level up a few notches. I discovered the cool breeze accidentally from braking suddenly, however I have tested it many times. Additionally, my right blinker works in the mornings but it gives me a "fast" blink in the afternoons. Other than my thought that my car is possessed, what could be the issue?
The AC only works if the fans work. So maybe you have an electrical gremlin interfering with a couple things, brakes/ABS/blinker and fans, and when the fans go out, so does the AC. I'd be more concerned about not having working blinkers or ABS or lights than a working AC for safety reasons. Since you say slapping on the brakes causes things to work again, if only for a short while, you may want to take a look at your battery connections and terminals, make sure none are loose. Also check wiring harness for any loose connections or frayed opens that might be causing a loss of power to any components if they shift around. Again, the AC will not run or be cold if the radiator fans stop.
