2006 Hummer H3 - Page 6 Questions & Answers
Anti theft is on and wont start
Sounds like you are in need of a new exciter ring around the ignition lock cylinder. You can get by for a bit by letting the key stay in the "ON" position for 15 minutes and the system will re-learn the key, but once this starts it does not get better and will happen more and more frequent. I suggest making an appointment at the dealership or a competent repair shop soon.
Why are Check Engine light and zigzag road drive not vanishing from the dashboard?
Well the check engine light and zigzag lights are probably connected - the zigzag light is probably for traction control.
If there is a problem with the engine the traction control warning light will come on too so the driver knows it is disabled.
You would need to have someone check the engine computer for trouble codes to know what to test.
Starter not working with remote
The remote start isn't compatible with your hummer. The factory security system isn't able to allow a remote starter to work with it , just the way it was designed for security. You can bypass it with a adaptor but you would have to disable your security system. Most professionals won't do that, you can fin a back yard machanic to assist you. But then it affects your insurance rates now that your security system is no longer working. If you can spend the big bucks some professionals can get the viper brand of remote start to work on hummers. I've experienced this with a 07 H3 tried an inexpensive aftermarket starter it worked twice on the 3rd time it would then make my hummer go into anti-theft mode and wouldn't start engine for 10 min, the lights would work on inside it would turn over when I turned the key but it wouldn't start. I took it back to the company that installed it they woul reset it and it woul happen all over again. So I then went to a different company explained situation they again reprogrammed it and told me the last people were setting it with the driver door open so it wasn't going to start without the door open. This time the remote start only worked once then the 2nd try would go into anti-theft mode making me wait 10 min before it would start the engine. I couldn't spend the $ to try a viper brand an they charge you to uninstall them so I have since sold it and just kept the key fobs so the next owners wouldn't have the same trouble. The second company did suggest trying a relay system to see if that would solve the issue but I didn't get a chance to try it, so maybe mention trying the relay system with your currant starter before paying for a expensive system.
CLUNK IN STEERING SHAFT
Sounds like this vehicle may have had some suspension or accident damage. It needs to be put up on a lift, engine running while someone turns the steering wheel back and forth, a second technician under the vehicle inspecting for where the interference exists when the clunking happens. I don't recommend driving this vehicle. If you need further help, reach me via phone at
