My turn signal lights wont work on my 95 firebird formula
Go under the dash on the drivers side, and locate the two flasher stat units. These are small round aluminum 'cans'. They plug in, and have flat blades on the bottom. (You of course won't see these flat terminal blades until you unplug them)
One is for the turn signals. One is for the four way flashers. I can't tell you which one is which.
Past this point, check all the grounds for the turn signals. The wiring harness at the front will have one, or two leads, (Wires), coming out that bolt directly to metal. Either sheet metal for the car, or to the frame. These leads have flat, round terminal ends on them, with a hole in the middle of the terminal.
The lead's terminal end bolts can work loose causing a bad ground, and/or, there could be corrosion in-between the terminal end, and the area of metal it bolts to. If so, use sandpaper, and clean the terminal end, plus the area of metal it bolts to.
There are ground leads, (Or lead), that come out of the rear wiring harness also. Check these.
Still no?
Then your turn signal bulb sockets have corrosion in them. This causes a bad ground.
You may be able to use a rolled up piece of sandpaper, and clean the socket.
(Also touch up the lead, {LED. As in the metal lead}, contact point in the middle of the socket. This is for the Positive connection, but it doesn't hurt to clean it while you're there.
After this is the turn signal switch in the steering column.
(My money is on a bad flasher unit)
