First I have printed the Seq. and brake light ops pages and they do help. Unfortunately I am a novice. Maybe my more savy friends can narrow the path.
All headlights work both high and low beams
Both sequential tail lights function properly (but now have been converted to the new electronic units). all lights function in the parking light mode. Both right side turn signals work correctly and left side rear works as it should. However L. front turn signal does not function and brake lights do not function.

Do I have two seperate malfunctions or one and how do I swap parts to reme dy the problem?

Thanks guys,

Ken

You may have two seperate problems. The turn signal and parking light should be a double filament bulb, Maybe the turn signal filament is burnt out. First check the bulb to be sure both filaments are good. If there good turn on your turn signal and ground your tester good and see if you have current to the bulb. You could check before the connection under the hood and also by the light it self. Be sure your getting current to and from your stop light switch with your tester, Someone should step on the brake while you test. Sometimes one filament will drop on the other and cause more lights to function then are on. I Don't think you have a ground problem because your parking light works.
