Since I bought my 2006 Tahoe the Service air bag, Service Tire monitor, and
Service Brake booster warnings come up in the information display. Around a month ago it also started saying Service 4WD. The service 4wd came on once and the next few days it stayed off. Then it came back on and went out for a couple days. Now it seems to come on almost anytime I drive it. The past couple weeks every once in a while the stability system disabled comes on too. And sometimes when that comes on the traction control dummy light comes on.
When I press the 4 low or 4 hi buttons in park or neutral it doesn’t do anything just stays in 2 wheel. Yesterday when I was driving it wouldn’t go much past 20mph and kept jerking like it wanted to die out and lights were coming on in the cluster. It eventually started running as it does normal but it was concerning because I had to pick up my kid from school.
Has anyone had these issues? Is it the wiring, like a bad ground or something somewhere? Or do I have issues with every single one of these parts of the vehicle? I’ve done a lot of google searching and watched videos on YouTube about bad grounds. Today I removed and cleaned the ground wire on the passenger side that bolts to the back of the block. The ground wires that are on the driver side under the radiator. The three ground wires that are on the frame by the driver side front door. And the ground wire strap on the drivers side firewall. I wasn’t able to get to the other end that bolts to the block. After doing all those I drove it around and the service air bag, service brake booster, service tire pressure warning were on from the start and after about a block the service 4wd warning came on. It ran okay but it usually does. It was just that one time yesterday that it wouldn’t get over 20mph. I’ve read that people have cleaned these ground wires and their problems went away. I guess I’m just not lucky. If anyone has any advise or thoughts on this please let me know.
Thank you
