Replace the blinker relay, located on the fuse panel. Buy it at any automotive parts dealer.
Bad fuse?
I just had the same problem with my 95 intrepid and it was the sending unit that needed to be replaced.
you probably need a new turn signal flasher .
In a 1995 Isuzu Rodeo pickup, the blinkers, gas gauge, and temperature gauge may stop working due to a blown fuse, faulty wiring, or a malfunctioning instrument cluster. A common issue is a blown fuse in the fuse box that controls these components. Additionally, a failed ground connection or a problem with the vehicle's main wiring harness can disrupt the electrical flow. It's advisable to check the fuses first, followed by inspecting wiring and connections.
Could be a bad flasher
what is a window release?
If just one side stops, look and change the bulb that isn't on. If none work, replace the fuse or flasher.
You have either a bad flasher, or one of the bulb's are burnt out.
u need to replace with a turnsignal light switch . there is a short in steering column
Blinkers
seat belt motor is bad
If you already checked your bulbs then check your fuses, usually this is the case when all the lights stop working at the same time.
