With my 94 sonoma my tail light burnt out but both my back up lights and my break lights work. Ive checked every fuse and replaced the bulbs and still nothing. Is there a relay or something else that could of burnt out to make my lights not work?

If the tail light fuse is okay-the problem is coming from the headlamp switch assy-

Well I couldnt find a fuse that was just for the taillights. So would a test light work to see if the switch is going out? My head lights work when I turn on the switch

Check T/L CTSY 20amp in the I/P fuse block-and test the brown wire on the headlamp switch it should have power when you put the switch on

So what I need to do is keep the switch plugged in and take a test light and check the brown wire with the switch on? If there is not power to the brown wire what else is wrong. Ive check every fuse there is more then once and there all fine
