There are a few resons for this, usually bad wire connections or a short. It is best to take it to a mechanic that is an automotive electrician to diagnose the problem. This is the best advice on this I can give, but if something is killing your voltage regulators. Also have the alternators checked at an auto parts store, they may still be good. Check the battery and charging system, usually free at auto zone or advance. If you have a week battery the security system can drain the battery.
If your headlights, horn and everything work, I would have the ignition switch checked out. Make sure you checked all ingition fuses and relays first.
Then something is on pulling power from the battery. Check all lights and relays.
No, a battery charging problem will have something to do with your alternator 90% of the time. The other 9% of the time its the battery itself that can't hold a charge, the other 1% is engine electrical relays.
Your alternator is shot.
Assuming you have checked the bulbs, check the brake light switch.
Have you checked the relays?
have u checked ur relays?
Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.
that my be caused by a faulty fan switch
Power door locks have relays located inside the cabin fuse box. Locate the relays for the door switch and see if they need replacing. If so replace the units.
I found that the fuel relay is the same number as some of the other relays such as the horn. You can check fuel relay by replacing in the horn relay if the horn works the relay is good.
A person can check the wiring, to see if anything is shorted out. A person also needs to make sure the battery is not too low, and that the alternator is working properly.Ê
