If the dash lights are on the same circuit as the park lights. Chances are if no dash lights... no park lights. Unless the dash light dimmer switch is on the low position. Check park light fuse. If no brake lights... which are on a different circuit and you are sure the bulbs are ok check brake light fuse. If fuse ok, unplug brake light switch at brake pedal and cross the terminals with a jumper. If brake lights work, the brake switch is faulty. If still no brake light operation suspect a wiring issue
Check and confirm, that headlight bulbs are glowing.If the bulb itself is faulty, it will not light.If bulb checked out, ok, then other possibility can be headlight fuse in the engine compartment fuse box.There are two 15a fuses located in the fuse holder assembly on the driverside engine compartment.Check both this fuses.Also check the relays in the fuse compartment.-------- If any of the fuse or relay is blown, replace that and see.But if all fuses and relay checked ok, then its quite possible that problem is with head light switch itself.Its getting short.------------ This should help.Thanks.Helpmech.
Check all turn signal bulbs, front and back, you probably have a blown bulb that is shorting the circuit. If all lights are ok, try removing them and installing one by one while circuit is energized, tif the fuse is blown on the first bulb try another location, his way you double check that the bulbs are not at fault. if it blows the fuse again, check your turn signal switch, it may be defective.
Are the bulbs out of the sockets and the fuse blows? Take bulbs out and check again Place one back at a time if fuse was OK with bulbs out to locate bad bulb. Otherwise....... Do this........if still needed with bulbs out and fuse blowing. Put a circuit breaker in to replace the fuse of the same amperage. It will trip off then back on. Use a standard cheap magnetic compass........place along lighting wiring........the wire with current will cause the needle to jump as circuit breaker trips on and off. Follow path of current to problem.....the compass will stop moving once past the shorted /grounded wire/connection.
Check for blown fuse on stop light circuit supply,
Check the lamp socket ground connection is is ok.
Use a test light to verify power is arriving at the stop light bulb socket (Note - Ign sw probably required to be ON for stoplights to function). If not, use the test light to check for power at other points in the circuit.
Troubleshooting Procedures - Read Completely Before Beginning (American Car) All Brake Lights Not Working
Check System Fuse: A fuse is used to protect the brake light circuit from amperage overload. If the fuse has failed it will not allow the electrical current to continue to the brake lights. To check the fuse, first locate the brake light system fuse in the fuse panel which is either under the dash or under the hood in the power distribution center. Connect the test light to a ground like an engine or dash bracket and turn the ignition key to the "on" position. Using the test light probe both sides of the fuse. If the test light illuminates on both sides the fuse is ok continue onto the next step. If one side of the fuse illuminates the fuse has failed and needs to be replaced. If the fuse fails as soon as it is replaced or when you apply the brake pedal the brake light electrical circuit is shorted to ground. Rarely a system short can occur, a car repair manual is needed to find the wiring schematic for the brake light circuit. Once the brake light wiring has been located inspect and repair as needed.
Check Brake Light Bulbs: All cars have three brake light bulbs that create the brake light illumination affect. If all of these brake light bulbs fail no brake light operation will occur. I know what you're thinking, you might say all three brake lights at once? But in reality one brake light went out at a time and you did not notice. People only tend to notice something when they almost run into the back of your car to help persuade them to inform you the brake lights aren't working. Remove any of the brake light bulbs to confirm the bulb is ok or burned. After the bulb has been removed inspect the filament and replace if failed. If the brake light bulbs are ok continue to the next step.
Checking the Brake Light Switch: A control switch is used to connect the brake light electrical circuit. This switch is located near the brake pedal lever. Basic switches have just two wires, power in and power out to the turn signal switch. Use a test light that is grounded and with the key in the "on" position test for power at one side (wire) of the switch, then press the brake pedal while testing the opposite side (wire). It should illuminate the test light, if electrical power is connected through the switch go to the next step. If no power is detected through the switch the brake light switch has failed and replacement is required. If your car is equipped with more than two wires integrated into the brake light switch a car repair manual is needed to locate the proper brake light circuit wiring.
