This is puzling me, all lights are working ok but lately a burnt light bulb warning light is flashing along with the left turn signal. Right turn signal is normal.

Where do you think I should look.

Thanks for all the help you bring, I silently read everything here everyday and I am thankful to everyone.

Also check the bulb socket's contact tab to the metal circuit for any burning or corrosion. Do this for all bulbs in both tail light assemblies.

Wagon or sedan? (sorry I should know by now)

It is a sedan 4 doors.

In the sedan's wiring, the only common electrical path between the turn signal and the brake lamp common specific to the left turn signal is the ground return from the bulb sockets to the car body. Number one suspect is a small amount of resistance at the screw attaching the black wire to the body sheet metal, but you will want to check the flex circuit board end of that wire too.

Try re-tightening or cleaning that ground wire terminal.

Art, you wrote:

"but you will want to check the flex circuit board end of that wire too."

I had the engine running, left turn signal on, and a winter snow/ice scraper jammed between the brake pedal and the steering wheel to get also the brake lights on.

In the trunk I found the ground terminal screw well tighten. But at the other end the spade connector was hot. I must mention that in Canada the first 1982 production run was using the leftover 1981 5 lenses brake lights that were Bosch and had galvanized metal strips instead of the printed circuit. I have those.

The problem is a weak wire where it is pinched at the spade connector.

Problem solved and thank you everyone.

Do check all of the contact points on the galvanized metal strips (circuit). You have to look under the socket tabs. Once a spot rusts or corrodes enough to cause a noticeable problem it is very hard to repair.

I have done repairs some time ago. I used acid core lead/tin solder to fix a thin sheet of copper over the metal strip.

Yes, it is not an easy job but it works for now.

Oh, I forgot about those. Once it was on my mind as seen below:



And then the "hard wire" fix ...



But eventually I ordered some new lamps from Volvo.



To make them "minty" ;)

Hi Roland,

Clean the directional/bake/tail light bases and sockets with Scotch Bright,
use a thin smear of dielectric silicone and replace.
You may have corrosion in a lamp socket.

Check grounds and lamp connectors.

Try new bulbs as a set on bad circuit/s.

You may have to re-solder (re-flow) your bulb out sensor pins.

Good luck, Bill
