Before starting to attack this problem, I am sure someone has faced this problem. My turn signal switch works fine for horn, turn signals, and high beam. However, it will not stay engaged on either the down or up during signaling. Does someone know what is broken internally and has fixed this?

SOBill used to rebuild the turn signal units and had a stash of parts, but passed the baton on a couple years ago. I want to say John Taphorn took on the role, but my memory isn't what it used to be.
It is possible to repair, but quite difficult. There are small, delicate plastic parts inside that crack and fail, causing this problem. Getting the switch apart is not easy - the body is cast zinc which also cracks easily. I went to a lot of work to repair one, only to have it fail again. Attached some pics so you can see what is inside. Notice the crack in the little part near the pencil; that is the root cause.
Finally I bought a later model Lucas part off ebay. It required a slight mod to the mount bracket, splicing wires into the stock Pantera connector, and making a new cancel cam.
I fully concur with the above if parts are broken. Well mine was bad moving the "lever" and got stuck or not. I took the whole "switch "assembly out and started to clean it with lack thinner then Silicon oil (NOT DWW ok! it dries out and sticks) .. Was a process of some 3 ..or may be 5 repetition steps and time (!) ..lack thinner silicon oli..loop
There was a lot debris and old sticky grease all clogged up..now the thing is working fine.
hope this helps
thanks for the feedback. Exactly what I was looking for.
John Taphorn in Texas did the last few for us, but he's pretty much stopped doing them also, lack of replacement parts & lack of spare time. Wouldn't hurt to reach out to him.
Does someone have an email for John. I don't know him. thanks
Those small parts would be a very simple project for the most basic of home 3-D printers.
I seem to recall hearing sometime ago that Steve Wilkinson was reproducing the turn signal switches? But I haven’t confirmed that

Thanks all. I will call Steve on Tuesday and have reached out to John. Will report back. I have found a firm in Germany, Motomobil, that supposedly has the later switch reproduced for $229 and sells on eBay. Have not reached out to them yet. This switch has the same functions plus flash (apparently).
I think this might be it:
Uh Oh, Sharkeys going to get me in trouble with SO Bill. Sorry if I gave you the impression I was working out of the switch repair hobby. Honestly, it does take a back seat to my real job and racing hobby.
I am keeping my commitment to SO Bill to be a resource for the Pantera community. The cost for switch repair remains SO Bill's price of $125 and includes return shipping. No inflation here :^)

WHOA EXCELLENT! John offers fast turn-around, cost friendly, few pioneers still fixing things, you & I & some otheres. Glad you wrote this, I stand behind your work, excellent!
