My water temperature gauge likes to dance around about 1-2 mm. It's not constant but definately common enough and I'm pretty certain it's just a bad ground somewhere that needs to be cleaned.
That said, where should I look? I know I can clean up the plug for the sender (which if I read correctly is the one behind the blue sendor under the j-boot) but where else can I look? I wasn't really able to find anything else in my search.
Thanks,
BB.

The water temp signal actually grounds through the sensor to the engine block. Most common cause of a "dancing" pointer is the connection to the sensor. If you other gauges also "dance" look at the instrument panel grounds under the dash, LH & RH inner fender. If it's neither of these things causing the problem it's likely you guage pointer/needle damper spring is weak, no repair just swap out the guage.

My gas gauge was doing that. I took the instrument panel off and the connector on the back was not on all the way. Has it always done this or is it a new issue? Have you had the instrument panel out recently?

It's been doing this for at least five years but it seems to have gotten a bit worse recently (or maybe I'm just paying more attention to it?). The cluster has been out a couple of times since it has been doing this.
I'll go ahead and clean things up at the sensor and, if that doesn't work, I'll pull the cluster and check all of the connections. If it's still doing it after that I may just continue to ignore it.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
