I have a 1991 Laredo and I'm having problems with the right turn signal. When I turn it on it will flash that its working inside then it will go completely to a solid light like its not working. I checked the bulbs and their ok. Could this be a ground wire thats shorting or maybe a relay switch thats bad?

If the bulbs are okay, then there's a problem with the flasher relay or the multi-function switch that connects the circuits going to the signal in the flasher relay.
