a quick query...the tail lights on my 1990 240 all function but not properly...i checked the connection - white plastic piece with wires, but when i connect it securely all of the lights come on leaving me with brake lights that don't illuminate...if, however, i tweak the connection, the lights will go off which allow my break lights to function but leave me without nighttime running lights...turning the headlight button on the dash does nothing.

does anyone know how i can fix this? i tried to sand the connections but the problem remains...any ideas? could i possibly not have the double filament bulbs in the right place?

thanks

you may want to try a little solder on all the pins that the white connector fits on. A slight Thickening of those pins with solder may help in giving a good connection on all of them.

All Volvo bulbs are single filament. Check the bulb numbers and cross check the to the owners manual.

Double filament bulbs are used in the 240 1986+ lower outer location for brake and tail lignting. Also used in the two locations in each front corner light - no obvious reason for why.

The bulb socket configuration won't allow a single filament to fit where a double filament is to be used. Not vice versa, either.

On that lower outer bulb, be sure that the right side holder is white and the left side is black.

The white connector with its little pincer connection system begins to fail when the copper film in the pincer begins to oxidize. It gets hot and burnt a bit, and connections get iffy.

Try removing the little pincers and making them just a wee bit tighter. Not touching, just close.

Just some ideas,

Good Luck,

Take a good look at the circuit boards where the wires connect at the tail lights,chances are they are worn and have a bare spot.Also look at the connecters themselves,make sure the gap between the pins isn't too big.
