1998 dodge caravan

sometimes my turn signals work and sometimes they do not. The emergency flashers work fine. Also the air conditioner and circulation buttons flash on and off.Can you help please? Thanks, Frank

Since the flashers are working ok then I would guess the problem is with the turn signal switch.

The blinking lights for the AC system is a trouble code. The shop will know what the code means.

I replaced the switch and turn signals still won,t work. Any other advice on what to do next? thanks, Frank
