Does your Fiero have the "paddle buttons" steering wheel found in many SE, GT, and Sport Coupes? Are yours broken? Do you still have all the pieces? If you do then there is a RELIABLE way to fix them!
When the buttons break, they seldom do so cleanly. This is actually a good thing! A "dirty" break allows nearly perfect realignment of the parts, and since the white part usually breaks a little inside the gray paddle, it's possible to get a totally invisible repair that lines up so well you'll never know they were broken. Better yet, the repaired paddles are stronger than original.
To start, head to your local auto parts dealer, or department store, and locate some "plastic welder", Devcon and others market it. This stuff is a 2 part Epoxy type adhesive. DO NOT waste your time with any one part adhesives, and NEVER use Cyano Acrylate "super glue" on plastic. Neither will last in this application, nor will they reinforce the paddle. (so called "super glue" hardly ever works well on plastic.)
Warning: This adhesive is Very fast setting. You will have only about 90 seconds of working time before the stuff is too thick to use. Use it out doors! It stinks horridly! Sniffing this won't make you high. It will make you sick or dead.
Take the switches off the steering wheel, and make sure the parts are free of obvious dirt. (the adhesive is a combination Solvent welder/Epoxy. As long as the parts are clean the adhesive will bind to it.) Dispense, and mix, the adhesive on a disposable item, like cardboard. Apply the mixed compound with a small wire, or tooth pick, to the edge of the white part, and inside the paddle. Press the pieces together, and hold still until the adhesive sets. ((if the break is deep enough into the paddle it will pretty much hold itself straight))
To reinforce the paddle, apply some adhesive to the back of the paddle joint. You can be fairly liberal. If you apply it to the front of the buttons stay well inboard of the thick paddle end or your repair may show. In fact, if your paddle buttons haven't broken yet, you could reinforce them to keep them in one piece through all but the most severe beating.
