The clock display functions fine for greater than 80% of the time. Sometimes when you start the car the Clock/trip computer resets. I am thinking it's a problem with a plug somewhere as the ignition switch was replaced less then 20K miles ago.

Any ideas?

Could it be a dying battery? Does it only happen if you start it or if you just turn on the ignition as well?

A loose connector ribbon between the clock/computer and the cluster would give that behavior, and it is a known nuisance issue. I'd check it, you have to pull the top dash pad to do so, see the odometer gear repair instructions. Any bulbs need changing in the cluster?

Sorry it took so long to try your idea, yesterday I removed the instrument cluster. (Removed the entire dash) I then took the cluster apart down to the speedo and re-soldered all connectors. I even opened up the trip computer and re-soldered the connectors on it.

Upon reinstalling the unit and starting the car and setting the clock, I went for a drive, the first time I shut off the car the clock went out and of course reset upon restarting. :(

Did you find a solution for the dash clock resetting? I'm having the same problem with my 96 850...
