98 Subaru Legacy, right blinker comes on steady,can't turn it off. Left blinker works fine. right blinker will work sometimes and then it goes steday again. Can't be the flasher as I have removed it and the light is still on. Any ideas?

When the right blinker comes on and does not flash , make sure the front and rear turn signal lights are lit. Usually a blown front bulb will have a fast flashing type of indication something is wrong. A slow or no flash means the rear turn signal bulb is not lit. Bad bulb, or bad connection to the turn signal socket.

Replace the right front or rear bulb, though it may be coming on at the moment it is probably faulty causing a short in the system. That is USUALLY the problem.

Pull that bulb out and look closely at it, it'll probably have one of the filaments(Tungsten wires) broken and crossed over to the other one causing a short to power and/or the bottom of the bulb has had the 2 lead contacts melt together. In either case the bulb will need to be replaced. If this doesn't fix the problem please let me know so I can look into it further.
