Question about 2006 Hummer H3

1 Answer

I have a 2006 H3 hummer and all of a sudden my check engine light comes on and car throttle drops to 50, very low and stalls at a light. The stab/system/tractionsystemfailure lights appeared then the egine stalled. It starts right back up but continue's to stall at low throttle and loses power steering and power brakes. We had the oil changed and every since then the check engine light would come on and off periodicaly. Technichnician says it was just a start up glitch. HELP PLEASE?? Car ran beautifully up until stalls, it always starts right back up but throttle lower's and stalls and power steering and brakes go out. My husbund disconnected the battery not too long ago to reset ck engine lite when tech forgot to when he changed the oil.HELP HELP HELP

SOURCE: 2009 Hummer h3 won't start

My H3 didn't start this morning. I noticed something unusual about my truck when I first tried. The alarm had a weak sound when it went off. The fact that it turned over but didn't start made me believe it was not the battery. I was trying to call the mechanic and a wrecker to get my H3 fixed. However, before that I got the wrecker out there, I went to Autozone. He told me it sounded like the battery and cold weather kills the battery. So 3 hours have passed and temperatures warmed up to a cool 56 degrees. I was going to put jumper cables but out of curiousity, I said well let me crank it and see if it was cold weather. Sure enough, it cranked right up.

Either way, I am going to take it to Autozone and have the battery checked. I can't miss another day of work due to an old battery.

SOURCE: 2006 Humer H3, Won't start and electrical resets itself

Check the battery terminals real good.Make sure they are clean and tight.Check and see if any of the side terminals are leaking. As far as the blower motor.It is more than likely that the blower motor resistor is bad.It is located by the blower motor.Hope this helps.Good luck.

SOURCE: check engine light came on after oil change

SOUNDS MORE LIKE SOMEONE KNOCKED OFF A WIRE CONNECTOR DOWN BY THE OIL FILTER AREA, RATHER THEN A RESET OF THE CHECK ENGINE LIGHT...SCAN OR HAVE THE SYSTEM SCANNED TO SEE WHAT CODE IS SET IN THE COMPUTER THIS MAY HELP YOU TO FIND THE CULPRIT IN 1/2 THE TIME, AFTER ITS DONE USE THE SCAN TOOL TO CLEAR THE CHECK ENGINE LIGHT, MAKE A NOTE OF WHAT CODE IT WAS AND DRIVE FOR A FEW DAYS TO BE SURE IT DOESN'T COME BACK AGAIN.
HAPPY MOTORING!!
