So I pulled my OBC out to see if the keypad bulb was actually bad, turns out it looks ok (??), checked the other 2 working bulbs to compare (they all looked the same), put it all back together, now none of them work. !!! What the freak?

So I've got a bunch of bulbs coming from BMA but meanwhile, are there other things I should look at? I gently scraped off what looked like some buildup on the contacts in the bulb housing on the OBC, metal's now nice and shiny, still no light.

Hmph.

Thanks in advance.
