95 LeSabre Speedometer Fans Gas Gauge Problems

[jitney]

Hi.. I have a 1995 LeSabre with 120,000 miles. Yesterday it decided to deviate from normal good running condition. The speedometer starting jumping back and forth from 50 to 95 mph, the gas gauge started jumping from full to overfull to three quarters and back, the air conditioner turned itself on and back off, and the fan started going off and on. I drove home and then when I next drove it, the same things happened. Any suggestions?

Ive had a similar problam with my 97 gm and all it was was a bad battery connection. Take the terminals out, clean them and rough up the connections.

Status update? What have you done, and how's it running?
