1/ There's no ground inside the column for the lights. Power goes to the signal bulbs then to ground to turn them on. Could be worn or need cleaning the dust and dirt out. Maybe remove and flush with electrical contact cleaner.
So pull all turn signal bulbs, check and clean all contacts? Just seem weird how it works one day and maybe not the next. It almost feels like it was something physical in the column. Thanks.
3/ As long as when driving the engine does not rev up when climbing hills it's not slipping and good enough for now.
No hills in Florida...will have to find a tall bridge!! Luckily we have one or two around.
I will definitely use your advice on the other two items as well, when I get some time. I'll keep you updated. Thanks Mike!
