Outside Temperature Display
This is the name my 968's manual gives for this display. Mine quit on a recent trip to Birmingham, AL. It can be seen glowing faintly at night, the temp reading not quite legible. In daylight nothing. I haven't found a replacement either on eBay or at parts suppliers. Any advice on removing and replacing this unit?

Maybe it just needs a new bulb?
One failure mode I know of (for the unit, not the bulb) is that the ground trace on the PCB gets weak. One time I had my temp display out, and I noticed a jumper wire soldered onto the PCB. I opened the unit to investigate and found out that the jumper wire was just bypassing the trace on the board that connects to ground.
If you can solder, that could be a quick and easy fix.

I haven't disassembled the unit and wasn't aware this could be a "bulb" failure. Are the bulbs available?
I do know the unit glows faintly when viewed at night, so something is alive in there. Thanks for the responses.

It sounds like the bulb is working, but it's the only thing that's working. If the screen has no digits displayed, then the light just gets blocked by the blackness of the screen, with a little light leaking through to give the glow you mention. Try putting in the ground bypass wire and see if that helps.
