Need help with Intermittent cluster of electrical features not working including the horn, blinkers, and the wipers. There may be others that also don't work but I haven't checked.
At first, they predominantly didn't work for a few weeks, but occasionally did.
Time of day, driving, weather didn't seem to make a difference.
Then. They predominantly worked, with occasional cluster of not working.
Since my wife drives the car more than me, and it's a safety issue, I didn't want to monkey around trying to chase down the issue and brought it to my mechanic.
Although the cluster indicated that it wasn't a fuse issue, I had the fuses, so did replace them all.
Of course, when in the shop, it worked without fail. So, they couldn't isolate the source.
They said that according to the wiring diagram, the affected systems only share a ground point in common.
They inspected ground point G200, cleaned some light corrosion, and verified good contact at circuits.
Worked on the drive home.
Then, went out in the middle of driving on an errand.
So, I had to go to manual signaling, with my arm out the window.
Any ideas? I don't want my wife to drive it when the issue could crop up at any time.
