Where is the fuse box on a 2003 Oldsmobile Alero?
The fuse box is located on the driver’s side edge of the dashboard behind the cover.
Do turn signals have separate relays?
Your turn signal relay is as easy to replace as a headlight, and they are almost never expensive. Some vehicles have separate flasher relays for turn signals and hazard lights. Be sure to check both systems while you’re thinking about signal relays. Hazard lights can be very important.
Where is the turn signal relay located?
It is usually located under the driver’s side of the dash, and is wired in-line with the turn signal lever and hazard switch buttons. When the turn signals or hazard lights are turned on, the circuit’s power is routed through the flasher, which only emits short bursts of power that cause the lights to flash.
What is the most common cause of turn signal problems?
Answer: The most common problem is a shorted light bulb causing trouble, an electrical short in the signal switch, or bad flasher relay.
What would cause turn signals to stop working?
The usual cause of inoperative turn signals is a defective bulb or flasher unit. Prior to performing extensive diagnosis, check the vehicles fuses to ensure they are not blown. Some vehicles utilize two fuse boxes, one in the passenger compartment and another under the hood.
Where is the flasher fuse located?
This small, cylindrical device is sometimes located in the fuse panel under the dashboard of the car. It costs about $3 in the auto parts store and works reliably for years.
Why do my turn signals not work but my hazards do?
Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse. Hazard lights and turn signals use the same bulb, so it is not the bulb, the lamp, or the cables to them.
What would cause a turn signal not to work?
You may be dealing with bad bulbs, a bad flasher relay, a faulty turn signal switch, or a bad wire or connector between the flasher unit and the turn signal switch. Check outgoing voltage from the turn signal switch to the faulty turn signal side of the circuit. Use a test light or digital multimeter.
