The flashers are working but the turn signals only work when they want to. I have already replaced the multi function switch on the column.Is their a seprate relay?
Turn signals not working all the time on 1995 GMC 1500 Pickup
There maybe just maybe another flasher.One for 4way and one for signals.

sounds like a poss bad connection maybe inside column. try tilting the wheel next time they don't work and see if that helps
