their might be an electrical problem in that area or you just might need to change the bulb but i think its an electrical problem
You need to check the fuse box in the engine compartment it's full of relays ans fuses responsible for gas and spark delivery.
Check the flasher.
A burnt out signal bulb, a faulty blinker relay, a faulty blinker switch, a loose connection or a broken wire are all things that can cause the turn signals not to operate properly.
If the rear window is not fully closed the rear wiper will not operate.
Your turn signals may not be blinking properly because something may be wrong with the wiring or fuses. Take your Harley to an authorized dealer to have diagnostic testing done.
Like many engine and diagnostic parts of the 1990 Toyota Celica, the tachometer needs the assistance of a fuse to operate correctly. Check the fuse box for a blown fuse for this instrument.
