I have asked several questions and never got a response. I have a 2006
Hummer H3 the engine light came on the code showed I needed a
thermostat. I replaced it and it was off. the engine light came back on, no
codes are coming up. What could be causing this?
Please answer me as quickly as possible I need to get my truck inspected
Since the light is on, you should be able to get a code. Clear the code or codes if you can and try again.
