It has been a few since I last frequented this site but I'm hoping that you guys [and gals?] can come through for me again. My sister's 1997 960 wagon's front and rear, passenger side markers are dead.
I've replaced the bulbs, checked the contacts, and *tested the wiring before and after the connectors*- all dead with the lights on/off. This particular bulb (side marker aka corner light/stop lamp) is a dual filament 1157 in the rear and 1157NA in the front (I think). The turn signal function of the bulbs work and I've tested the other circuts, so I know the grounds are good. No burning, corrosion, or excessive wear is apparent.

Since the side markers on the right side would appear to have gone out at the same time, I'm cautiously assuming that the wiring for these two side markers is on the same circuit.


I've searched for the past 20 minutes around this site and Google to no avail, though I may not be looking under the correct [chassis] keywords.
Is this a common problem? I'm crossing my fingers for documented fixes so I don't have to tear apart the whole interior. My last 240 wagon had the typical hatch hinge wiring failure that was a lovely task to repair but at least it was easy to figure out.

Thanks in advance, folks!

 

Front bulb is Turn and Park. Taillight combo bulb is Park and Stop/Brake. Turn bulb is separate in the Taillight.

Which bulb is out at the right taillight?


Nope, there are on different circuits. You might just have bad bulbs.

Front Bulb should be 1157N. Rear Bulb should be 1157.

Is the Bulb Failure Warning light on?

 

Ah, yes, you're correct- wasn't paying enough attention to such details.
All bulbs mentioned, front and rear, are new though I don't have a complete inventory of the other bulbs which aren't related to my issue (*see below).


*Yes the bulb warning light is on, though I thought it was due to a reverse bulb (and socket/retainer?) missing.
Yes, the front is an 1157na and the rear is an 1157.
I would love to have bad bulbs or contacts, I spent some time with the test light checking for any line that got hot with the parking/marker function toggled. I plan to go out and check all of the lines again to be twice as sure though I'm confident in what I'll find.

I appreciate your input btw.

 

Bad ignition:

I would check for voltage too. Are the bulbs not lit with engine running? Again - which bulb does not light at the right taillight?

 

I'll read that thread asap rspi, fellow Arkansawyer.
The bulbs I'm referring to work (front blinker does function- same bulb; rear brake light does function- same bulb) for their other functions but not as side marker/parking lamps.
The bulb I'm referring to is located at the bottom of the housing.
I can check voltage if I can find it in my storage.... that would be interesting :-X
