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.
It is quite simple to replace the turn signal switch on your 1990 Buick LeSabre. The turn signal switch simply plugs in and out.

I have a 1990 lesabre and im 90% sure its a 16 gal.
On my 1990 Buick Lesabre it is on the underside of the dash in the middle of the car. Go to you ash tray and look under the dash. There will be a rectangular hole through the plastic and the plug will be in there.

The 1990 Buick LeSabre air conditioner recharge valve can be found on top of the air conditioning compressor. The air conditioner recharge valve will have a blue top.
After consulting several sources, someone finally called a local Buick dealer who informed me that a 1990 LeSabre does NOT have a map sensor, it was the Mass Air Flow sensor that needs replacing.
