There's an older thread on this but the forum suggests a new topic in that it's over 90 days old. Anyhow, both my mirrors were a bit balky. They wouldn't adjust consistently. The problem was the switches. I ordered new ones from Ramco ($53) and they now work as they should. I took a couple of photos of the little light bulb for future searches. A dental pick is just the ticket for prying the bulb fitting out of the switch.

I just replace a bulb in mine. Got it from FOT.

Thanks for posting the photos. I think my switches are different, but it helps to see where these bulbs are hidden.
