This happens so often-- you totally focus on a problem at hand, not realizing there is a much simpler solution if you could just see it.
I have a GMC duramax truck. I tried to change the front left blinker bulb but couldn't get access to it. Checked youtube-- first video explains you need to remove the grill to replace the bulb. wth? Next video- this guy has a shortcut. Jack the truck, remove the front left wheel, then x, then y, then z. wth?
So I lived with it not working until next time I needed service from my trusted mechanic. He said: "we have 1 guy here who can replace those." Some skinny kid appeared, and was able to contort his hand and arm through the grill and replace the bulb. But no one else can do it.
I can still hardly believe a truck is designed whereby you have to remove the grill to change a light bulb.
