Auto Dim rear view mirror leaking black goo / not working
I noticed that since I purchased the truck a couple months back that the auto dim rearview mirror never dimmed, even though the little light was on. I had the trans rebuilt and it sat outside at the shop for a few days in the sun. when I picked it up today, there was a black ball of semi-liquid goop hanging off the bottom of the mirror, and the mirror itself was all greasy inside (behind the glass, as if someone sprayed a grease mist behind the glass). Based on the above, I'm guessing it finally gave up anything it had left inside.
I've seen some replacements online, and one is the Gantex mirror with temp, compass and such. I already have an overhead console with that stuff, and would prefer a replacement that has no other displays. I would however like to add homelink to the mirror. I found one Gantex that was set up similar to what I'm looking for at $140, but I wasn't sure if the wiring would have to change? Does anyone have any recommendations?
