Service Lights

[bluethang04]

I have a 2004 Chevy Tahoe, ABS, Brake, Service ride control, service 4wd drive lights are on in the dash board. Also the speedometer doesnt work.. can anyone help or have had this problems before.

The simple answer is take it to the service department and get your sh!t fixed! Thats a ton of service lights to be on all at once.

However, we're gonna need way more info bro. Did you just buy the truck? If so, were these lights on when you bought it? (god I hope not) When did they come on? Did they come on all at the same time, or have they been coming on one by one? Do you have rear air suspension?

+1 on getting it to the shop...my best guess would be the stability control system is on the skids...

Sorry, I wasnt clear on my last post. I have 04 tahoe LT fully loaded. I had truck at shop saturday they say the ecm is bad, which is causing abs, brake light.. Service 4wd and service stability is a bad relay in the dash.. Local muffler place says take to dealership cause they cant fix dealer parts... Is this something thats common in a 04, and what are the cost to repair those parts.
