85k... nice!
Yup, out sight outta mind guess. My garage is bit an@l, I mean geez... when you ground the low press connector the brake light comes on dim, which tells me thats workin. I've looked up schematics and can't find the missing link to this issue.
Others... plz chime in!
Does it light up when you step on the parking/emergency brake? If so then I would look at the low pressure switch as the possible fault.
