Dash lights go on and off, odometer needle drops to zero, races back up, rpm needle drops and races back up as does the gas gage needle. car does not lose power. dash light module???

I don't have a solution for you yet. If I may ask for additional information please? Does the "Check Engine" light ever come on? Either way why not take it to an auto parts store like AutoPalace / Autozone / or PepBoys etc. where they offer a free computer analysis of you automobile's on board computer & engine control unit. Perhaps there is a message there that could help you diagnost the problem. Good luck.

Sounds like you may have a problem with the circuit board on the backside of the instrument cluster.

my guess is that since you hit a bump in the road that its possible that a plug has come loose from the back of the dash.. remove instrument cluster and inspect for loose or broken wiring and connectors..

check you speedo sencer maybe replace it this will fix your problem

Replace the ignition module for the rpm and the spark control runs off this item

Have you checked the fuses? Look in the owner's manual for the locations... you might have just blown one.

Is your dash cluster working? If not this will cause the problem.The gas gage, temp gage, odometer, and transmission shift indicator will not light up. Give the dash a hard thump above the cluster this may or may not temporarily fix the problem.

Have the computer checked

You need to pull the dash and check the guages look for any burning or melting. You may just need to replace the pannel in your dash, pretty easy work. If not start checking the wires and cables that come out of your faulty guages.
