92 GV No turn signal on right rear

[stapletonr]

I have a 92 grand voyager and the problem is I have no right rear turn signal or stop light. Tail light is ok and all of left side is ok. Good bulb but no power to turn or stop. I did trace some wires to under the scuff plate at drivers door but no power there for right side rear turn or stop wires. Rt front works but goes very fast....could it be the flasher unit? The idea of replacing the switch isnt appealing to me at all so if there is something I missed Please help.
Thanks in advance for any and all suggestions.

BTW...I have power to the taillight on the right side but none to turn signal or hazard on right ride'

Can't be too specific without a schematic. It's a good bet the turn sig switch is ok since the right front blinks. It's a good bet the ground at the rear light assembly is good since the parking lights work. My guess is the sockets on the right rear are corroded, you have a broken power wire, or as you said the combination flasher is bad. On newer vans all 4 corners have individual outputs from the flasher. If yours is the same I'd say go for a new flasher. Might try reseating it and tapping on it first. If you want a schematic buy a Haynes manual or go to Alldata.com.

Can't see the flasher fixing the brake lights though. Since the left side is good, the switch at the pedal is good. I would guess again either a socket or wire.

Have you done any recent maintenance that could effect this? Did the brake and turn sigs break at the same time? Upper brake light work?

I tracked some of the rt turn/stop wires to the scuff plate at the drivers door and they show no power. Left side is ok showing power to both turn and tail lights. The 3rd (upper) brake light works fine.

Yup, parking lights are probably powered by a parking light relay. Turn sigs are powered by the combo flasher. All my assumptions are based on a 96 schematic. By recent maintenance I meant before this problem came up.

No recent maint was done. Its my wifes vehicle and she said the turn signal indicator started flashing real fast a couple of weeks ago. last week-end is when I started checking bulbs and using a test light. I replaced the flasher unit today in hopes that was what it was but still no turn or stop lights. Any suggestions on where to go from here? BTW RIP, I appreciate all the info you have given me.

That's about as far as I can go without a schematic for a 92. If nobody else can help I would recommend buying a Haynes or Chiltons manual or go to Alldata.com. $15 - 20 at many auto parts stores or on the internet will get you schematic plus a handy reference the next time something comes up. Some libraries have them.

I'm guessing now you probably have a broken wire somewhere. Without a schematic the only way to find it would be visually which means dismantling and tracing wire color codes etc. You could try pulling the flasher and see if any of the wires give you continuity on a meter between the flasher socket and the right rear lights. Tug the wires going to the right rear sockets. Might give you some idea of whats up.

I have a chiltons but it doesnt really tell me much about the wiring but will try pulling some wire and see what I can find....Thanks for all your help, I appreciate it and this forum.

Looking at the left side, tail lights off, foot on brake, left turn signal on, does the brake light blink when the left turn signal is on?
Start with the headlight switch since it seems to be a common point of failure. Make a copy of the wiring diagram and highlight or check off areas of the circuit you test. Below is a link to a wiring diagram.

On a whim I replaced the turn signal switch but no luck....still dont have any power from the flasher unit to the wire for the right side turn but do have power for tail lights. Show continuity from ground wire under scuff plate drivers side to turn signal wire at rt rear socket though.

An option if you can't find the broken wire. If you know for sure which wire off the flasher socket is the power wire to the right rear brake/turn sig light, you could string a new wire outside the van to complete the circuit just to make sure it works. Use piggy back (my term) splices that only poke the wire so you don't have to cut the old original wire. Once you know it works, cut the old wire a few inches back from the flasher and permanently splice or solder the new wire in place, then install the new wire under the scuff plates etc. . Make a permanent splice at the light assembly.

Piggy back splices are used a lot for sterio installations. Might find them at radio shack. They just clip on the old and new wire and a prong pokes through the insulation and into the conducter to complete a circuit. I wouldn't use them permanently.

Have you looked at and tugged the wires on the back of the flasher socket?

I was looking at the schematic KimMG sent you. I don't put Autozone schematics high on my trust list but, now and then they are good for something. It appears both the turn sig and brake light power goes through the headlight switch. Doesn't make sense but, that's the way they depict it. The way it's drawn there are arguements that point away from the switch but, at this point I wouldn't count it out. Try having someone watch the tail lights while you wiggle the switch, apply brakes, and use the turn sigs. Check the wires on the back side.
