Marcus,
This switch is for a non A.C. system. There were two different switches designed. One is for A.C. application and the other is for non-A.C. application.
I have rebuilt both switches and know that there is a physical design difference but don't understand why Buick engineering felt it necessary to make the difference. I do not have the switch that was designed for the A.C. application. If you were here in the states, I would suggest that you send me your switch and I would rebuild it and send it back after rebuilding. Shipping would be a huge expense I think to do that though.
Regards, Loren
