My 2004 PT Cruiser keeps dying out at stop signs when I have the AC turned on

My 2004 PT Cruiser keeps dying out at stop signs when I have the AC turned on. I’ve had tune ups, the idle valve changed out, and other things. But, it still dies at idle when the AC is on. Please tell me you’ve seen this before.”

As a matter of fact, I have seen that before. Your PT Cruiser has a two speed fan that cools the radiator. It has low speed, and high speed. And many times the low speed circuit of that fan motor will burn out. SO, when you’re idling with the AC on, the low speed fan doesn’t work. Then the AC system builds up too much pressure from the heat, and strains the engine enough to make it stall. Have the low speed circuit checked on your radiator fan. Odds are it’s burned out and you just need to replace the fan motor. It’s a rather common problem with those Cruisers.
