This reply is taken from the Chry repair archives. I had the same problem and tried this repair and it worked. "Most of the time this problemalways occurs right after the battery is replaced, even though there are no other signs of a loose battery cable. The combo flasher is extremely sensative to LOW VOLTAGE. in turn the combo flasher does not have enough energy to cycle and it will BUZZ. Check the battery cables and the auxillary smaller battery cable at the battery as well as the auxillary body ground." "The 1993 & 1994 LH's use a 4 wire flasher. The 1995-1997 LH's use a 5 wire flasher. Be sure you have the correct flasher and thoroughly load test the power and grounds to the flasher. The combo flasher will flash the lights faster than normal if it detects either high resistance or a burned out bulb, this is done by design to alert the customer. The flasher is actually a logic module that detects current flow. This is unlike all of the earlier hazzard and combo flashers of the 1980's where they were simply circuit breakers. When a bulb burnt out, the flasher would not cycle and only the one bulb would light up (not flash)."
More than likely the flasher relay is defective, replace it.
If your hazards still work, most likely your turn signal relay needs to be replaced.
Look at the relay for the flashers, that should fix your problem.
fuse or blub is out or blown, or wiring is bad, or the relay is bad.
I just had the same problem with my 95 intrepid and it was the sending unit that needed to be replaced.
on the Chevy beretta there are 2 flashers one is right next to the steering column to the behind the plastic dash piece,this is your turn signal flasher replace it and your signals should work.
to the right of the steering wheel there is a fuse cover and 3 or 4 relays, turn hazards on and feel which relay is clicking, if relay not working, its the tall looking relay,
it is in a small black box under the hood to the left if standing in front or drivers side. ...
Defective flasher relay.
The Flasher Relay is more than likely defective. Some vehicles have 2 relays. One for the turn signals and one for the hazard lights. Replace the Flasher Relay for the turn signals.
Most obvious thing to check would be the flasher relay located under the bonnet
Sounds like a relay, which should be near or in the fuse box.
