Another brake light issue

Well look in some ways you should not even "be into" the switch. Treat the switch as a "black box" and that you have certain inputs and outputs. If one of the inputs is bad, then go back to that. If one of the outputs is faulty, then it's "in the switch." And of course be aware of the connectors.

So, in other words, go to the TS connector and check there.

Basically, you have "hot" power into the switch from the hazard flasher
You have switched power into the switch from the TS flasher
You have the switched brake light power into the switch

The outputs are the left front and the right front, and the left rear and the right rear.

The switch steers the brake light power to both rear lamps when centered, or cuts off brake power when one side is "turning"
