I experienced different symptoms when I had that problem... but it is worth checking anyway.

What happens is the ground (and other signals also!) have to pass "across" the connector on the driver's side tail light assembly. By that, I mean, there is an edge connector style socket and plug + current needs to flow from pins on 1 side of the socket to the other, bridged only by the plug. It's a terrible design: putting 2 unnecessary connections in a signal path (ee 101: connectors are prone to failure). Corrosion on the pins weakens the connection, causing heating, burning, furthering the poor connection + eventual failure... with enough heat, it might even be possible to cause a short in there that would cause the symptoms BAAB is experiencing.

The conventional repair is as Saabnutt says to wire a separate ground. Our indy did that long ago on 1 of our cars, and then a different set of pins went bad. My "solution" (for now) was to just clean the pins and reassemble... it worked, but I anticipate future failure, at which point I will cut the connector + point to point solder every wire. imho, that is the only permanent solution...

I agree. I'd make sure that is taken care of before moving on to other things!

James...
