Cluster warning lights

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL, CEL and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System, MIL Malfunction Indicator Lamp, CEL Check Engine Light.

First have the battery tested with a load tester and also (most places will do both for free hoping to sell a battery etc) the charging system tested.Either battery, charging system are bad or you have a drain of the battery somewhere.A authorized dealer would be a smart move.

If the alternator passes the bench test but is not charging on the truck, you have a problem in the wiring between the alternator and the battery, or the alternator and the key switch.

if you have a check engine light on check the codes first.

Have a dealer or repair shop diagnose the issueThey have the test equipment & reference material to resolve

This is a common problem with gm speedo's. You will have to get it rebuilt. You can find these on ebay rebuilt and ready to go in your vehicle.

The most common cause of this is the seat heater grid is defective, due top the high cost of repairing it have it properly diagnosed before replacing the parts.

do a manual test gauge or a very good scanner will give you pressures that are in motor before getting to gauge ,there is apossible short in wiring ? or gauge is shot .hope this helps you.

Not sure about this at all, but check into what happens when you have a faulty fuel cap (weird weird things have been known to happen).
