Check the switch.
I'm not a mechanic / technician but I would assume that would be your headlight switch ( I lost my headlights , taillights , and dash lights on my 1971 Mustang one night while travelling on a highway , pretty dangerous )
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
On most vehivles the live feed for the taillights brances from a connection in the back of the trunk. It is probably a poor connection or damp in this junction. If the whole cluster isn's working it is probably a poor earth.
I just had this problem. First check your fuses then disconnect the relay and reconnect it, they get loose from time to time i need to find the fuse
The best way to troubleshoot why the taillights are not working on a 1999 Toyota Corolla is to first check all of the bulbs to see if one is burned out. Then check the fuses to see if there is a blown fuse. If the problem is still not found, a code reader in the ECU (computer) might show a code that will help find the problem.
If you have no brake lights or tail lights then you've probably got an electrical problem. Check the fuses first and see if you have one or more blown.
it may be your headlight switch, all mentioned circuits are routed through it
The 2004 Sorrento has a major problem blowing out taillights and headlights. The dealer said they found no problem but I have never had to change so many bulbs. The only thing I can guess is there is a grounding issue some where and techs now a days are just parts re placers and do not know how to trace problems.
Troubleshoot a problem by being patient and understanding. Do as much fact finding as possible and do not assume that the problem is petty or a lie.
What is your problem with tail light options?
It's a short circuit in the wiring. You'll have to get a multimeter or test light and go over the whole wire for the headlights and check for continuity . If there's a current through it all is what youre checking. Hope it helps .
check your fuse box you probly have some bad fuses or possibly in the wrong places
