zonie77 Posted February 13, 2007 Report Share Posted February 13, 2007 I'm posting this here in hopes KHE or anyone with GM experience can help. My brother has a 2003 Bravada that has an intermittent starting problem. It had worsened to the point that the engine will occasionally die when hitting a bump but we cannot get it to die by hitting the steering column. The shroud is off the column so the wiring is visible. It seems that if it won't start wiggling the wires will let it start but it isn't consistent so that may be misleading. The wires that seem to let it start one time may not be the ones that seem to let it start another time. Steering wheel position does not make a difference. When it does not start the dash lights dim and the tach needle ocassionally jumps. There also seems to be a quiet buzzing noise from the dash. I've researched the recalls and this one doesn't seem to fit. Mfg'd 03/03. Any techs who've seen or heard of this give me an idea. Thanks! Link to comment Share on other sites More sharing options...
Ranger Posted February 13, 2007 Report Share Posted February 13, 2007 Have you checked the connecting rod from the key cylinder to the switch farther down the column? Link to comment Share on other sites More sharing options...
zonie77 Posted February 13, 2007 Author Report Share Posted February 13, 2007 This does not have that link. It is a different design. The switch is very close to the lock and is a different style switch. The switch may get replaced tomorrow but I hate throwing parts at it. I've been searching for an Olds or Bravada forum and none of them come close to the Caddy forums! Link to comment Share on other sites More sharing options...

kev2 Posted February 13, 2007 Report Share Posted February 13, 2007 Some thoughts Have you checked for codes, -B series may not set mil? Does vehicle have a emote starter? Link to comment Share on other sites More sharing options...
zonie77 Posted February 13, 2007 Author Report Share Posted February 13, 2007 No codes, no remote starter. I've seen posts of ign sw problems but the symptoms were different. Link to comment Share on other sites More sharing options...
kens96 Posted February 14, 2007 Report Share Posted February 14, 2007 Any chance the hot cable to the battery is grounding out? I had this happen on a car where he cable shielding had rubbed to the core on the steering column near the power steering pump. When I hit a bump or turned the wheel a certian way the car would cut off. Just a thought. Link to comment Share on other sites More sharing options...
zonie77 Posted February 14, 2007 Author Report Share Posted February 14, 2007 My brother put a new switch in tonight and so far it hasn't failed. He took the old one apart and said one post looked burned. I'll post the resolution in a few days . Link to comment Share on other sites More sharing options...
KHE Posted February 14, 2007 Report Share Posted February 14, 2007 It will be interesting to see if that cures the problem. My neighbor has an older Bravada - a 1997, and I think he had to have the ignition switch replaced a year or two ago.

zonie77 Posted February 17, 2007 Author Report Share Posted February 17, 2007 It looks like it was the ignition switch. It hasn't failed since it was replaced. The moving wires allowing it to start???? The only thing I can figure is the switch snaps in and has a little play, moving the wires may have moved the switch and let it get a little more contact.
