2002 lesabre custom won't keep running
Asked by trucker101 May 17, 2013 at 11:54 PM about the 2002 Buick LeSabre Custom Sedan FWD
Question type: Maintenance & Repair
It was fine but now when I turn the lights on or heater fan or interior lights up on bright it
quits running. The daytime running lights are on and no problems then any of the other
elec things come on it quits? I checked the alternator & it's charging fine. I drove it to
town, parked all was fine. Come out of the Doctors & this was happening.

Thanks, yes I have a book on this car. I've checked relays & fuses and everything else I can think of.When it first happened the low beam light on drivers side wouldn't come on when the daytime running lights did. I figured a burnt out bulb, then I changed it with a known good one & it still never came on? So I played with the the relays thinking something was up there but all seemed normal. Now with the key on and with the engine running (or not) as soon as I start to use more elec it stalls out. If I leave the headlights off, then neither the signals will blink or the horn honk when the motor is running? I am now pulling my hair out one at a time!! LOL

No, it was parked all winter I used my truck & they don't salt here, it gets very cold but not much snow.
check the wiring harness leading into the air breather... the main pcm is located in there... could be a wire touching or frayed.
