Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, I am Randall Do you have a testlight or voltmeter to test a couple things?
Ok, i need you to remove the tail light relay, turn key On, probe the relay terminals, how many have power? 12 volts?
Ok, remove the tailight fuse, turn lights ON, probe both the termiansl the fuse plugs into, either have power?
ok, sorry, you said you checked fuses, let me see if I have a diagram to send
Ok, understood, the tail fuse is in the INSIDE fuse box, It is a 15 amp fuse located top left corner, See the link I included, Swap it out even if it looksok, If still no lights? then I lean very strongly to the combination/headlight switch as being bad even though headlights still work, The switch contains different circuits for different things, I can send the wiring diagram also if you feel it will help, It is likely going to be the combo switch or the fuse is bad
did you swap the fuse? did you do the power test?
that is odd,. where are yours located, this is a 2004? is it 4x4?
that may help, I have pulled the factory diahrams for a 2004, and this is the layout it shows
I wrote the INSIDE fuse box, none of the pics are that fuse box, The one inside the vehicle, lower left, under dash, drivers side, did you go that box?
then a short can be difficult from my end, I would start by removing the bulbs one at a time or all at same time indicating a shorted bulb socket, With so many lights in the cirucit, any one could be bad, No way for me to say exact where the problem lies but most common? a bad bulb socket
sorry I had to step out, this is the only way to start the repair., even in the shop we have to do this, hope all goes ok
