Stop light problem

A while ago I followed advise here and switched out my flasher unit to a Signal Stat 24v 263-4 and all was well with my lighting. Today my directionals stopped working and I found mounting the flasher wrong way up was a bad idea as it collected water with my old leaky canvas. Nice brown rust is inside so I ordered another. I figured I might as well test my brake lights today and here is the problem. No brake lights with my switch in "service brake lights" yet when I switch to "service head lights the brake lights work??? Any suggestions where to start looking. Thanks much
UPDATE: I was mistaken, I went out awhile ago and tried it again. While I was at it I moved the turn signal switch and the brake lights came on in the correct light switch positions. Therefore I also have an issue with the turn signal switch I guess. First chance I get I may see if the turn signal switch can be taken apart and cleaned. I was going to delete this post but if I cure the problem it may help others. BTW, I usually have no help so I made up a simple brake pedal applying tool years ago so I could check if I have brake lights. I used an old clauking gun, piece of rod stock and a U shaped piece of steel. I'll post a photo if anyone is interested.

Camping mirrors and mirrors with clamps work nice at the back of the jeep when you're working on it. You just stick your head out the door and look back. Beats walking back and forth.

Found the problem. After installing a new flasher things still weren't right. I took the turn signal switch apart and the contacts looked like crap. Some careful work with a scotch brite pad and applied no-corrode contact grease it works like a charm.

The issue you had is VERY common with the m series solid-state switch. What you did simply has to be done periodically.

Most folks aren't aware that the brake light circuit runs through the signal control switch on the solid-state system, it is by far the most common place that brake light issues will be found.
