I got a 1999 Dodge Ram 1500 Laramie 4x4 with a 5.9L
the truck runs fine, but the gauge on the other hand isn’t working properly. The volt gauge is pegged all the way left, even when the truck is started and running it doesn’t move, the oil pegs to the right once started . Not exactly sure what the issue is . I’ve tested the battery and alternator and they are fine as well as the oil pressure. Anyone have any ideas? Thanks

 

Could be the cluster is bad or a wiring issue.

 

Do a cluster/gauge test and then share the results. Test goes as follows:

1. Begin with the key off and vehicle stopped.
2. Depress AND HOLD the trip odometer reset button and turn the ignition switch to the ON position BUT DO NOT START THE TRUCK.
3. Continue to hold the reset button in for about 10 seconds until "CHEC" appears in the odometer display, then release the button.
4. A series of 3 digit error messages MAY appear in the display (IF you had cluster problems) but if not then the display will proceed with the segment test; all segments then each individual segment in sequence will illuminate. If any do not, the cluster is a candidate for service. If all are OK then the next test follows.
5. The bulb of each amber indicator lamp that the cluster controls will light individually, if not, the bulb may be bad, the bulb may be loose or the bulb holder may not be installed correctly. The red indicators are LED's and if they don't light in the test the cluster must be replaced.
6. The gauge actuator test is next. The cluster circuitry will position each of the gauge needles at three different calibration points and then return the needle to its relaxed position. If any one does not respond correctly, check the spring-clip terminal pins on the cluster. If those are OK the cluster is bad.
7. The self-diagnostic test is completed. The cluster will self exit the test mode and return to normal at the end of the test. If the key is turned off during the test or if the PCM sends a message on the CCD bus that there is movement of the vehicle, the test ends. Try it!

 

Ran the test and everything passed except the oil and volt gauge. The volt gauge didn’t budge and the oil one stayed stuck all the way to the right. Im going to take out the cluster and check for any damages , thanks !!
