Right turn signal periodically stops working

Every few months my right turn signal in 97 Buick Park Ave stops working completely. Will work fine 1 day, stop working for a week, then just start working fine again. Fuse is ok.

Likely a bad connection at the bulb or a wire connection. However try replacing the light bulb.

Same thing happened with my 2000 Chevy Malibu. Found out that there was a “Bulletin” out to repair the faulty turn signal switch. The dealer will not replace though if the turn signals are working. If it is not a bad connection or the bulb, check with the dealer.
