That is a manufacturing defect associated with your instrument cluster. My local dealer replaced my entire instrument cluster for free (truck was out of warranty) when my speedometer showed 100 mph in a parking lot and my oil pressure gauge read 0.

Probably corrosion in connections from sensors to the dash circuit board. Could be components in the dash circuit board.

Bad ground under the dash, no doubt. Check all of your chassis ground connections.

2004 f350 when speeding up, lose all power to truck (radio, gauges, etc)


sound like faulty alternator voltage regulator. check alternator out put at battery with engine idling should be 13.5 - 14.5 volts at 2000 rpm if not lower you have faulty voltage regulator.also check alternator drive belt and check alternator for loose wires.besure turn off radio before disconnecting negative battery cable to keep from locking out radio losing code.

Dash lights flicker and or go out on 04 Chrysler Sebring Conv.


On thedash of my 2003 sedan sebring ,My dash ilumination lights for the speed,temp,tack\rpm and fuel are unlit.
I found that there is a paper thin plastic across and behind all four of these gauges which lights up all four gauges,if working correctly, There is a very poor connection to this thin film lighting system ,basicaly a wire terminal used as a staple and that very well could be your problem.
It as far as I know would require whole gauge assembly replacement! because dealers dont sell such small portions of some assemblies!
I myself will attempt to crimp this poor connection on my car without damaging thin film! there are no bulbs for those four gauges too iluminate!

Speed-o-meter and RPM gauge do not work


if the engine is running fine and no limp mode no engine lights. abs is working then the only other thing could be the dash may need replacing as putting the battery on wrong can blow the electronics in the dash as they are both linked. i ask is there any other problems as the rev counter work to ecu in line with speedo and the abs unit to determine timing etc. speedo works of the abs system the connection between them both is the board in the dash board. you can replace the boards in the dash but you will need replacement dash parts to do this but remember if you change the dash you need to log the miles as new dash will have different miles and uk mot log your miles to dvla. USA i dont know you would need to look into this.
