Bulbs or turn signal flasher, maybe even the switch.
If the signal light fuse is blown all the signal lights front and rear would not work. If you have one signal light out I would first suspect a bad bulb or bad connection.
Sounds like a weak turn signal flasher
how much would it cost to replace the heater coil on a 1999 buick leSabre
A fuse usually blows when there is a short. It's possible you have a short in the wiring someplace.
Either the throttle plate is sticking or the idle air control is not responding to ecm signal.
I have a shimmy or small vibration while driving the interstate on my 1994 buick lesabre - if i was to check the front and rear bearings - how would i do that and what would i look for
what would cause a 1994 Buick LeSabre v6 to turn off going down the road.
I would highly suspect that there is a bulb out. Remove the Eight million hand tightened screws and the trunk lense will come out to access the socket. But check to see which one is out first.
The spark plug gap for a 2003 Buick LeSabre should be set at .060 inches. The best spark plug for this vehicle would be an Iridium plug.
Ruin it the way you a "pimped out" car usually would be
Check battery and cables
