Oil Pressure Gauge Issues:
A non-working oil pressure gauge is a common Instrument Clusters problem in GM vehicles from 2003-2006. The second biggest issue from vehicles in this year-range other than the instrument cluster issues is the oil sensor/switch also going bad.
We replace ALL gauges regardless if it's working so rest assured you're in good hands.
If You've Already Had Your GM Cluster Repaired & Have This Issue:
If your instrument cluster was already repaired by us and your oil pressure gauge is stuck, erratic, pegged to the other side even after our repair do not be alarmed, it is not the fault of the repair. ALL gauges were replaced. It is most likely a faulty oil pressure switch and you will need to replace the faulty switch.
- Aftermarket oil pressure switch can be purchased from auto stores such as, 'Napa, Autozone, Advance Auto, CarQuest, O'Reilly Auto Parts, etc.'
- The dealer also sells the OEM ones.
Once the oil pressure switch has been replaced the oil gauge should now display the correct engine oil pressure.
This can also be verified via a mechanic's scan tool who can see the values of the gauge on their scanner.
