stevebfl:
just to followup if you have had the chance to verify the S25/5 and B11/7 for a 915 560sel.

My diagram shows that S25/5 is for 86 and 87 models only, and B11/7 does not show on my schematic nor on the component location page.

One temp switch for aux fans referred to in the ACC function page is referred to as a switch in the receiver dehydrator. But again, it does not show in the schematic diagram at all.

Could it be an intermittent grounded connector in the ACC push-button control unit?

am quite puzzled and hope you could help...

thx again
