No parking lights @ rear tails, yes ! do you have a wire diagram, get one, there in the back of the haynes repair manuel. could be a bad connection @ rear, a wire may be shorted, corroded, after all, these wires are subject to road salt, debris, etc., inspect them closely, turn your parking lights on, pull on the wire harness, wiggle it, see if lights come on. have a helper watch for you when you do this. do your brake lights work? make sure your tails are in good shape, these light components corrode inside, so inspect them closely, then, follow the wire harness from rear to front along frame rail, to check condition of wires, all of them, if in good condition, check under dash, where you replaced switch, check fuses, use your wire diagram to locate and under stand the color of wires that come from the rear, and there function, remember, we are dealing with the tails, what powers them, and which ones do what. ignor all other wires, keep it simple dude. have a trouble light with you, It looks like an ice pick, with a wire lead on it and a aligator clip on it to attach to a good ground. electrical problems have a bad ground, remember that. by now you should know your wires for the tails, usually there green. with your taillights on, and your trouble light hooked up, check each wire to see if the troublelight goes on, this wire is good, if troublelight does not light up, wire has no continuity, therefore its bad. patience is a virtue, remember that. test wires on a circuit you know works, so you can feel more positive about what your doing, these problems can be easy, they can be @#$!%& , remeber, your trying to power up your tails, keep it simple, one wire @ a time. good luck,

SOURCE: brake light on 2001 chevy blazer LT 2wd

When my blazer did this they had to replace part of the wiring harness in the steering wheel. It took forever for them to get the parts because we live in nowhereville, but once it was in it works again and no problems. I had to take it to the actual chevy dealer because none of the other places had a clue. good luck.

SOURCE: Tail lights don't work on 1998 Chevy Silverado.

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

If the break lights in my 1986 c corvette works but the tail lights do not, what could be the cause


Blown fuse ,bad headlight switch,or wiring issue.
the tail lights have there own fuse and are powered through headlight switch. Do the front running lights come on? If none of them work, switch could be bad if front work and rears dont, check bulbs and power to them when lights are on

The tail lights do not work. The headlights, blinkers, and brake lights work. I checked the fuses and they are all good.


It can be faulty tail light bulb or its issue with tail light control switch or its wiring's are short.

Check the voltage at fuse slot of tail light.Do you receive 12 volt there.If not,then it says tail light switch is not receiving power supply.

My 2002 ford ranger running lights and instrument panel dont work


12V power passes through 15A fuse 33 (the one that keeps blowing?) in the battery junction box and on to the main light switch. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the park filaments of the dual park/turn lamps. These lights remain on when the headlight switch is turned to HEAD.

The main light switch gets its 12V input from 7.5A fuse 11 in the central junction box and the same 15A fuse (33) identified above. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the instrument panel dimming module and module output is applied to the panel illuminating lamps.These lights remain on when the headlight switch is turned to HEAD.

The input to fuse 33 is hot all the time so should read 12V. If you read 12V at the TAN/WHT connection with the fuse out, something is definitely not right. I'm sure you have noted that the fuse is common to the non-functioning circuits you mentioned.

Brake lights doesn't work


Either the brake light bulbs are faulty and needs replacement.But if in case the brake light bulbs checked out ok and the bulbs are glowing by connecting brake light bulb to battery directly ,then in that case the brake light switch is faulty and it has to be replaced./ Check for 12 volts at the terminal in the light socket when the brakes are applied.If there is 12 volt then its a bulb problem ,but if no 12 volt then its switch problem.The brake light switch located under the dash above the brake pedal. ------------ Keep updated for any more queries.Thanks.

Why would both tail lights and brake lights go out at the same time on my 1989 toyota pick up?


Might 1st Check to see if the Fuse that goes to Your Tail Lights is Good.If Not Replace it.If that does'nt WorkTake the Rear Red Lens off and take a 12Volt Tester After Removing the Bulbs and Check to see if you have 12 Volts Reaching you Tail Light Bulb Sockets.And make sure they are Grounded Good.If the sockets for the Tail Lights have 12 Volts to Them ,Replace Thye Bulbs With New ,Hopefully this Solves Your Problem.

Need fuse schematic


if the fuse was blown the stop lights on both sides would be inop, also if the stop light circuit were dead u would be unable to get the trans out of park, use a 12 volt test light and test the brake light switch at the top of the brake pedal, u can buy a test light from Autozone, kragen and others for about $5 US. If the system has power cjheck the bulb socket it may be defective, use the 12 volt test light while someone pushes the brake pedal. let me know what u find and i will give u further assistance as ness.
