1. Check the Blinker Fluid Level:
Open the hood of the car and locate the blinker fluid reservoir. Check if the reservoir is empty or has low fluid. If necessary, refill it with the recommended blinker fluid.
2. Inspect Blinker Bulbs:
Remove the lens cover of the blinker that's not working. Check if the blinker bulb is burnt or damaged. If the bulb is faulty, replace it with a new one of the same wattage.
3. Clean the Bulb Socket:
If the bulb looks fine, take it out and clean the bulb socket using a wire brush. Dirt or corrosion in the socket can affect the electrical contact and cause the blinker to malfunction.
4. Check Fuse:
Locate the fuse box and identify the fuse responsible for the blinker circuit. If the fuse is blown, replace it with a fuse of the same amperage rating.
5. Check Relay:
The blinker relay is an electrical component responsible for controlling the blinking sequence. If the relay is faulty, it can affect the blinker operation. Try swapping the relay with another functional relay from the same car or a compatible vehicle.
6. Examine Wiring:
Look for any loose, damaged, or corroded wires in the blinker circuit. Clean and reconnect any loose wires and repair or replace damaged ones.
7. Check Flasher Module:
If the above steps don't fix the issue, the flasher module might be faulty. It's a device responsible for regulating the blinker's flashing rate. Replacing the flasher module can resolve the blinker problem.
8. Seek Professional Help:
If you're unsure about any step or if the blinker issue persists, it's best to consult a qualified mechanic or an auto electrician who can diagnose and fix the problem accurately.
Remember that electrical issues can vary based on the specific year and model of your Oldsmobile Eighty Eight, so referring to the vehicle's owner's manual or seeking assistance from a professional is recommended for precise troubleshooting and repair.
