Hi all, having problem with my 1991 240 passenger side stop light, this is the tail light, stop light combo on the bottom of the light stack, the tail light part on both sides light up so it apperes there is power to this section of the light, the drivers side and the third stop light come on when the break is applied but the passenger side put the passenger side does not, checked the bulbs, wires look like they are ok, cleaned the contacts on the bulb socket, thought it might be the brake light switch, but if the other two stop lights are working wouldn't that indicate that the break light switch is ok? Stumped at this point, any help greatly appricated, Thanks

Greetings all, thanks for all the help, seem the problem was a the bulb socket not making proper contact, took it out cleaned the contacts, bent the contacts forward a bit, put it back, tighter fit and its working fine, thanks to all for your input, appricate the help

I r also perplexed.
You've applied all other respondents' guidances?
If the 'parking light'=position light'='marker light'='running light'='trail light' (we could say lamp in UK parlance) 5W - 3 candle power (cp) filament inside the dual filament bulb at the lower most passenger side rear 240 Wagon lamp lights when you have the headlight switch to 'position lamps', the bulb is connected to ground through the contact on the metal barrel.
Brake light/ tail light '1157' US / 'BaY 15d Euro' - UK spec bulb.
21 W/31 cp (Brake Light)
5 W/3 cp (Tail light - that you write lights up both sides)
Turn signal lamps front and rear, and reversing lamps are:
1156 US / Ba 15 s Euro / UK
21 W/32 cp
From:
http://new.volvocars.com/ownersdocs/1991/1991_240/91240_21.htm#114
Though in your 1991 Volvo 240 owner manual in your glove box, if you have it there.
You sure it is an '1157' US / 'BaY 15d Euro' dual filament bulb?
Are you using the correct bulb holder?
The high center third brake light years use a bulb holder with two contacts: one for the position light and one for the brake light. The bulb holder is black.
(Though in 240, with high center thrid brake light and newer, sedans, the right dual filament bulb holder is white, the left is black. Though 240 wagon uses two black dual filament bulb holders in the bottom brake light red lens bulb chamber. Wagon does not use white bulb holder at all.)
Examples:
Bulb side-
I dunno which of the +VDC tabs power what filament. You can easily see the tab that bends over to contact the metal bulb barrel to ground the bulb and provide -VDC to both filaments.
Back side-
I've seen some that install the dual filament position light / brake light bulb into the single filament bulb holder used for turn signal bulb and reverse light bulb. It looks like:
Finally, and on sedan and coupe only, at least in the modern era 240 sedan and not used on wagon, is the rear tail light bulb holder that carries the single filament 5 W/3 cp bulb for rear running light. You should not find this on 240 wagon with in the era of factory high center third brake light.
It will fit into any fo the four wagon tail lamp sockets, yet I'll guesss you know not to use this or have none.
Finally, if you have a multimeter set to check for at least twelve volts DC, at the passenger lowest red lens bulb chamber, use the multimeter to test for proper voltage.
The contiguous strip along one side of the vertical row of four bulb chambers is the -VDC ground and should come connected to a black wire.
Among the wires terminating to the tail light, see the yellow wire that terminate at one of the free standing silver metal contacts that one of the dual filament black bulb holder makes contact when you gently insert and twist clockwise. Your +VDC that powers the brake, or stop light filament..

Else, like john sargent describes, the fault may be in the bulb failure sensor as it has a solder weld fracture. The stop light, or brake light switch, is "upstream" of the bulb out, or bulb failure sensor. Inside the bulb failure sensor, the single +VDC 'downstream' from the stop light, or brake light switch, is split into three unique paths for the rear brake light, left and right, and the high center third brake light.
It may mean you need to inspect the bulb out sensor, or perform an unpowered continuity test between the +VDC connection for the passenger side yellow brake light wire, to confirm continuity of the passenger side yellow brake light wire and the yellow wire 'hole' in the bulb failure sensor socket. If you have continuity, suspect the bulb out sensor. If not continuity, a fault in the intervening connector.
It may be corrosion has formed between the bulb failure sensor socket pins and the wire harness socket? Disconnect, reconnect, & test?
Or test, as already mentioned, with the brake pedal pressed, with brake lights on, and see if you get +VDC at the passenger side yellow brake light wire and ground.

With my sister's 89-245, I noticed that the same lights were used for park and brake but there was also an available position that wasn't being used (fog lights?). So I moved the brake wiring to that position on both sides.

As Art wrote, I am having trouble understanding exactly what your brake light problem is.
I like to check for voltage with the simple little tester which looks like an ice pick with a clear handle (lamp inside). Connect the ground lead near the lamp you want to test, and test a known good circuit. A faulty ground can be detected by putting the tip of the probe against the lamp's metal shell while the circuit is energized. If the test lamp glows, you have a bad ground.
I recently repaired the brake lights on a 1991 245. The Lamp Failure Relay had failed, and the third brake light wasn't getting power. The Lamp Failure Relay is the round red electrical device under the dash on the driver's side. It can be tested using the same simple tester while the brakes are applied.

I took time reading your original post with the symptoms, but I couldn't quite nail down exactly what behavior was being described.
Just in case you've run into this rather common puzzle, I'll outline it here, as I have not yet seen it addressed in your responses.
Terminology: Tail lamp = Running lamp = parking lamp. Stop lamp = brake lamp.
Wagon symptom: You get light both sides with light switch set to park, or with headlights on. You get light both sides with brake pedal depressed. The turn signals work both sides. The backup lamps work both sides. The puzzle occurs when you find one side or the other does not light up red when both the parking lamps are switched on and you step on the pedal.
Cause: The shell of the dual filament lamp is not getting grounded. Suspect corrosion in the bulb holder itself, or poor contact to the housing's metal ground strip.

That was pretty much the problem, had some time over the weekend, took the tail light out, the stop/tail light socket was not making complete contact, cleaned and bent the contacts in a bit, put it back in and "magic" it worked, been a few day now and still working, thanks for your input, appreciate your help, stay well

Replace the bulb if you havent already or swap from left to right and see if it follows the bulb.

Thanks, tryed the bulb thing replaced it, no brake light, still working on it

What I remember on my 84 245 and 240 was the ground wire needed a jumper ground wire connection between the two tail lights. Check and follow the circuit board between the two Tail lights. Check power if you can with an electrical meter between the center prong and ground.

What he said, then...
Push the metal tabs rearward such that make better contact with the metal plate.
Also, check that you have 12 Vdc on wire on the passenger side that actually lights up the brake light part of the bulb. If not, the broke is between the left side and right side and you need to check the wire that runs between the two.
Good Luck!
Let us know!

I'll give that a try, I did try the bulb thing, didn't work. Raining now have to wait till tomorrow, thanks for your input, I'll let you know

I would say it is time to get rid of the circuit board and hard wire your tails to rid yourself of this constant heartache. The whole project takes about a day to complete.
