Question about 1989 Jeep Wrangler
Like any bulb, it needspower and ground. Probe the contact in the bulb socket with a test light and check for power. If you have power, use the same ground you did for the test light and connect a short piece of wire there and probe the socket with the bulb installed (insert down into the socket between the bulb and socket) If the light comes on re-ground the socket.
If you get nothing for power check the harness closer to the switch...if nothing there you may need to check the signal switch to make sure an internal contact hasn't failed. I'm betting it's a bad ground though.
