Hey eveyone I'm new on this forum . I'm having a problem with my ac. my 94 ls400 AC works reverse. I have to turn on the fan to turn on and off the AC. but when the light is off, the AC is on. When the AC light on, the AC is off. I can control the AC if I turn on the fan which allows me to hit the AC button on and off, but only reverse as stated above. If any ideas please let me know thank you.
