How Long Will This Fix Last?
Tom installed the replacement used die-cast ring for the directional the other night. He used permanent-grade Loctite on the retaining screw. Ariel's sister, Brianna, has been driving me since Ariel left for a trip California. So far the fix is holding.
Brianna did mention that the running the wipers for a while causes the wiper switch to get very hot. Tom's going to have to disassemble, clean, and reassemble that switch.
