Trip meter set, odometer, speedo & tach quit

I took a road trip recently and set my trip meter. Shortly after, my speedo and tach dropped to zero. And I noticed my odometer was froze, the miles were not adding up . I discovered if I pushed in and held the trip meter , everything worked again. When I released it, back to zero. After a search here I found a few things about unplugging the instrument cluster and cleaning all the connections back there before putting it back together.

I have the service manual and I'm ready to tackle this, I just wanted to see if this is a common problem and If anyone has any tips before I open her up. Thanks.
. . . . picking the lines with my twenty-nines . . . .

Be careful pulling things apart and gently rock the connectors. Make sure, if there is a lock on the connector, to get that loose before forcing anything.

Loose connections are not uncommon on such devices. Use some spray contact (available at Radio Shack and most Automotive stores) cleaner on anything that "plugs together" and DO NOT SMOKE while using it.....for some time after.

If you spot corrosion on any connector, spray with contact cleaner and see if it dissappears......if not... spray again......if it is really stubborn, you can use swabs or sharp object to dislodge, but if using any metal object, disconnect Battery first.

Corrosion on gold/silver plate printed circuit board edge connectors can be removed by lightly rubbing with a pencil erasure (lightly).

Lastly......if you are not sure you will remember how to put it back together, mark the connectors with dots of fingernail polish......1 dot on each side of a connector.....2 dots on the next....etc. May save you A LOT of time....

yes its common. I just had mine "fixed" today at the garage. It's done it only twice since then. I have to take it back. Good luck. If you gave to change the black connecter, you have to buy the harness also which is 750.00 bucks. the blue connecter is only 6.00.
