volvo 240 tail light not working

Hi,
I was wondering could somebody hellp me with my problem, I have a volvo
240 1991, problem that I am having is when you turn on lights tail
lights are not on but when I press the brake all four lights go on
instead two outer ones that spoustu. Anybody have any idea what is
going on with them? Thank you!

 

Hi Zoran,

More than likely you have a Lucas electrical system. Ala Jag, Triumph,
A&H, MG etc.

British Leyland autos, and apparently Volvos are just loaded w/ issues
due to Lucas systems. Admittedly the Volvo systems are not as bad as
some. Probably it is a relay, if not, reverse trace the harness from
the faulty lights. It may be that a brittle piece of insulation has
broken off and shorted out.

Best of luck,
-Z-

 

What Zeke said or possibly a bad ground. When all four go on are they
bright (like brake lights) or dim? You could make a jumper wire and make a
temporary ground to see if that is what it is.

This is a very common problem in most types of vehicles, and is most
often caused by a bad ground, usually near the rear harness connectors.
Look for a wire coming out of the harness with a round terminal that is
screwed into the body.

Thank You all !
The problem started when car was hit in rear quater panel on driver
side after the accident only driver side tail lights worked. After a
while I pooled all light bulbs out and cleaned conectors and still
right side didnt work so after I was done I unpluged the main wire
conection that goes to tail ligh and plaged back in and tail lights
worked fine for two days. Now they dont work at all only if I press
brake they all go on and they are all realy bright. also when I press
the brake my blinker erows go on to any idea whay? I am thinking maybe
i have a relay problem if there is one would you know where would be
located? Thank You!

 

Baloney!!!

Volvo 240 has the Bosch electrical system and nothing else!

There's a sep[arate ground wire from each of the circuit boards on the
rear lights. It is screwed into the body near each of the housings. From
you description it is either absent or not connected.

I've never seen anything Lucas in a Volvo, it's all Bosch.
