2002 dodge grancaravan freaked

Hello, Thank you for reading my post.
I was driving home at night and it was raining (not pouring) and all of my gauges (gas,speed,ect) starting flickering back and forth for a couple of minutes then went back to normal. This happened about 3-4 times for about a 25 minute drive. The van drove normal during the freak out.Went home slept & next day van was normal. Does any1 know what would cause or advice to check something ? Please get with me...

This is becoming a fairly common problem. If you do a search on the forum you'll find many threads about this and similar problems. Consider yourself lucky. Sometimes the gauges go, the van dies, and it won't restart.

It's normally caused by a poor electrical connection in a solder joint, connection or a computer circuit. Sometimes it's in the instrument cluster, its connector, or the body control or forward module and their connections.

If it happens again, smack the top of the dash. If it clears it up, you have proof of a bad connection. You can also do an instrument calibration by pressing the odometer trip and reset buttons simultaneously for 5 sec with the key in the run position. Welcome to the forum.
