If you have plenty of fluid it could be the Power Steering pump itself going bad or it could be the rack and pinion assembly.
Yea, the 1993 Buick Lesabre does have a fuse for the horn. However, there could be other reasons why the horn doesn't work, the clockspring or relay could be out.
It could be the steering wheel rotation sensor needs replacing. That's what was wrong with mine. It was done by the dealer so I have no idea how to do it.
Water.
Could be a burnt out bulb or a bad flasher unit.
I have a 2000 Buick Century costom and I replaced it but it leaks what could be wrong
Check for burnt out bulbs and could be a bad flasher as well.
take it to dealership
take it to a transmission shop. The problem is in the tcc valve body.
You could try learning celsius like the rest of the world. ;-)
the tps is bad-throttle positioning sensor
I COULD BE THAT IT IS NOT LINED UP, NEEDS SHIMMS
