I have a 1996 D R and have the same problem. Apparently the flasher switch needs to be replaced.
Most likely you have a flasher that needs to be replaced.
Check/change the fuse associated with the blinkers.
Change front light bulbs
Replace the Turn Signal Flasher Relay.
It may be a bad fuse.... Try that.
try replacing the flasher unit for the blinkers its a 3 dollar part
Blown fuse/? blown bulbs /?bad flasher.
check your fuses
There is also a flasher unit that makes them flash, try replacing that unit.
you probably need a new turn signal flasher .
There could be numerous problems that may cause this fault. Personally, my blinkers started going out (working sometimes and sometimes not) and what I found out is this...The flasher switch that is located in the dashboard above the radio is faulty. When my blinkers do not work i just tap down on the flasher switch without turning it on and my blinkers work again. Shotty electrical work in this car if ya ask me.
All Bulbs were replaced. fuses all checked, relay switch new and flasher, Also when the relay switch is in it gets really hot. Any suggestions
