I have a problem with brake lights and directionals. All parking lights work. Just passenger brake lights come on when brake is applied. Right directional did work. No left brake or directional. Just put new directional switch in and new 552 can. cant make heads or tails of wiring diagrams/ not the best at troubleshooting. any ideas of the problem? Thanks in advance for the help.

Any difference in the DS directional behavior when the parking lights are on? Otherwise, - if you are sure the TS switch is good and it was properly installed -, the sequential box could be a good possibility.

The bulbs are dual element, if the brake lights and turn signals work on only one side perhaps it's the bulbs on the left. Swap a couple of bulbs and see if it makes a difference.

bulbs are good. nothing when parking lights are on. now i have no directionals at all. hazard lights still work. i did change the voltage regulator. what wires on the directional switch could i check to see if switch is bad?

So... I guess your horn works then? :buck: Sorry, I couldn't resist. Hang in there, you'll get to the bottom of it. Johnboy has a good suggestion, check it out.

Are the problems the same now as they were before you replaced the directional switch ? Not sure for 1969, but the 1970 wiring diagram shows a 15amp circuit breaker/relay thats mounted in the dash area. I would check that to make sure its still working. When I had an issue with my brake lights, I learned that the inner bulbs work even if the sequencer unit(in the trunk) is unplugged. The sequencer unit is needed for the middle and exterior brake light bulbs to work...Joe
