I hear ya. I've had 3 or 4 people try to fix my factory lighter, I eventually replaced the whole unit but that didn't work either so I put this one in first.
Went to walmart last night and saw this one
in the auto section where the led's and other Accessories are.
It was $5 and took about 45 min to do.
I cleaned the defrost cover and center console. My wife had spilled her coffee all over it and in the vents so I was able to clean all that. Can't wait to see it light up tonight.
