Question about 2003 Oldsmobile Bravada
Just purchased with 62,000 miles and all known recalls/campaigns done according to GM service manager. (I'm very particular and picked this one owner Bravada because of its complete service history.) I do have the headliner out for repair, but have started it and run with no problems with headliner out. After sitting for about 1 1/2 weeks, thought I'd start it and let it run for a while. Started just fine, however, after a very brief time -- I'd say less then a minute -- I noticed the speedometer needle suddenly jump around and I believe, though not sure, I noticed other gage needles jump. Again, I'm not sure -- happened so suddenly -- just know that sudden needle movement caught my attention -- especially the speedometer! The parking brake was still on. I attempted to restart, but nothing; and then also realized that the information window was blank (not lit) with the key turned to start/run, The odometer is lit and everything else seems to operate -- radio, lights, etc. However, I did realize that I cannot shift out of gear even with foot on the brake and ignition switch turned to run. I checked battery voltage at fuse blocks -- 12.35 volts -- and the battery connections (even removed and cleaned, but really weren't dirty). I'm puzzled. The vehicle has been garaged and had all service done by GM. I've not had a chance to get full GM service manuals yet, so don't have anything to use for troubleshooting this problem. Onother tech here said they've had problems with the security system causing problems in them. I greatly appreciate any feedback / direction you can give -- Thanks! Bruce
Hi,check the voltage at the battery as you try to crank it for starter draw.I worked on a gm the other day that had the same symptoms.It ended up being the battery.It had 12.2 volts until i turned the key to the start position,then it dropped to 5 volts.Had a dead cell.Hope this helps.Good Luck!!!
