Question about 2004 GMC Sierra

1 Answer

I have a 2004 GMC Sierra, and my Engine Light has been on for the past month, it will start to blink as soon as I drive up a hill or increase my RPMs. Yes the Gas Cap is on. I also have a knocking noise that is very loud. And the other day I waz driving and the Dome Lights would not shut off the whole time i was driving, it kept sayin "PASSENGER DOOR AJAR" so we slammed all the doors shut and still it did not turn off. When we even turned the car off and locked it it would not turn off. And the car alarm will not turn on when you lock the car. PLEASE HELP!?

This is a well known issue with model years 2003 thru 2005. There is a chance GM will replace it under recall... Call the Chevy Customer Assistance Center 1-800-630-2438 to find out.

If not and you want it fixed, try Southern Electronics at http://www.instrumentclusters.com/.
