Go figure. Sanden AC system upgrade completed and the blower switch melts.
The switch is for an 85 635. PN 613 1138 1 317. Needed, wanted.
Note for all. In lieu of the OEM switch I used is a $20 variable speed solid state control.
The housing would fit in your shirt pocket. I stashed it in the nook above the glove box.
The switch came with a rotary control on a pig tail and stabs through the control bezel perfectly. 2 control leads & 2 load leads.
As expected, the heater core popped soon after the AC retrofit. While the dash is apart I thought I might find an OEM blower controller.
Thanks from Keith
