Help...PEGGING Guages

I have a 2003 Ford Escape Limited (2WD). Every 2 weeks ALL of the guages PEG back and forth. No light come on, but like I said evey analog guage PEGs to the far right then back to the left. This used to happen once evey 3-4 months but now it happens every 2 weeks. And it happens during normal driving operations. Speed is between 40MPH - 60MPH. Dealer can't duplicate problem to diagnose. Any one else experience this problem?

check power plug for gauge cluster, when gage spike to full scale it is indicating that you are loosing a ground connection

:2cents:
If the gauges read high, low, or oscillate in unision, check for a faulty instrument regulator. (Most of the time, one regulator controls all gauges.) I have also had a bad connection between the regulator and the printed circuit track.
