The gauges in the cluster are driven by stepper motors, these are known to fail. There are vendors on E-bay that offer services to replace the stepper motors. This would require you to remove the cluster from the truck.

Well,sometimes the gauges in the dash do go bad.Not often, but it happens. Tap the dashboard right on the gauge firmly with your fingers.Any change and you know you have a bad gauge.

Started out my oil pres. gauge only worked some times then the hole dash stopped working all together what could be wrong and can i fix without a lot of problems


A couple of things to check out. Sometimes the tiny stepper motors on the back of each gauge can go out. Easy and cheap to replace them. The other problem associated with this is a bad ignition switch.

Dropping oil pressure


You need to put a mechanical gauge on it to read actual oil pressure, sometimes the sensor is wrong, have seen the gauge be off (even on newer than yours). The first thing anyone would do is the mechanical pressure test with a screw in oil pressure gauge. That would be my advise.

89 C4 911 gauges reading incorrectly?


These cars are funky and this is normal...gauges on all of the earlier cars are for general reference...checking the oil level manually while the car is running and warmed up is the most proper way to do this...generally speaking, your pressure should drop as the car warms up, but still reach 5 bar on full accelleration (928's have the same gauge). The oil level gauge will actually increase as the car warms up...the difference can be dramatic.

this is just a rough guess, but i think it would be the battery or the alternator. Some part store have testers that they will check both for free.

Tach needle buried at park


Purchase a new keyless remote FOB. The signal from the remote is weak and loses contact with the anti-theft module in the instrument cluster. We have 2 sets of keys and 1 worked while the other caused the instrument cluster needles to jump and jam the gear selector. The problem is not the car's battery, alternator, wiring or instrument cluster.

2005 pontiac sunfire


I have the same problem.. i installed a toggle switch for the fuse so at least I can reset it while driving.. its still a pain so Im thinking my next step will be to drill a hole through the plastic and put in a small metal post to stop the tach from going past 7

has anyone taken theirs into a shop?
