I have a 2007 Avalanche LTZ, just replaced the oil pressure switch for the low oil pressure issue. Now I have an unusual electrical problem when vehicle is started and running, all gauges fluctuate a lot basically bouncing all over the place. All the warning lights are on in dash, info center cycles thru all systems with multiple problems. Tried to plug in scan tool but will not communicate with vehicle. Engine runs ok. Suspect corrosion or poor connection for communication system or faulty ignition switch? I doubt that replacing the oil pressure switch and screen caused the problem because everything was fine on road test after repair.
Any help with this would be appreciated.
