AC VACUUM SWITCH 2571501 AND 2096084 QUESTIONS

I just put a new switch in my 69 dart and had a similar problem. The replacement switch would turn the a/c clutch on when I pushed the off button. When I purchased the switch it said the switch was for my 69 dart, and I even looked up the number on the internet to make sure it was right. After I had this issue i did some more digging and found one website that said it was for a C Bodie. That was the only place that said that all other claimed it worked for an A Body. It might be the same number you have there I would have to check.
