Orange wire is + 12 volt to brake light switch . White is hot after brake light switch to turn signal switch where the brake lights are canceled for the left side when the left hand turn signal is activated and the same for the right side . so if all the 4 ways and turn signals work but no brake light on one side then the turn signal switch is bad. you can test this by getting a new one and just plug it in and see if the brake lights work before you take the steering column apart/

Sometimes the turn signal stalk malfunctions (doesn't return to neutral position after making a turn) and will also cause the brake lights to malfunction. They are both part of the same circuit. Bad grounds are a good place to start regardless.

I finally got around to looking at my brake light problem, it was a bad turn signal switch, I changed it out and everything works, thanks for the help.

That is the problem with mine...bad turn signal switch. My switch is worn on the inside of the column....Ijust have been too busy to tear down the column. By the looks of business, next year is gonna be busier....uuugh.

It was really easy after borrowing the steering wheel pulller and locking plate remover from autozone. The easiest way I found was to tape a wire to the end of the plug part and tape the prongs so they don’t get caught pulling it up through the steering wheel the tie the wire on the new one and pull it back through, took about 10 minutes but my column doesn’t have tilt or cruise so not sure if it will be harder

Same way tape a string to plug pull it out then retape it to the new plug and pull it back in with the column straight

My problem is not with the wire connector, its the actual clicking return to neutral mechanism. The mechanism is so worn that the turn signal will not return to the neutral position after completing any left turn

ok it could be a easy fix 1 the little cancel spring could be broke or missing .2) the cancel cam could be wore the frick out . take it apart both parts can be bought at any auto parts store.
