tail light brake and reverse not working 2003

[pierceandrew]

SO Brake light and backup light not working .signal works and normal lights on when you turn lights on. When i swapped left side
tail light assembly all worked. Is there a way to open up the housing to see if there is corosion or do i have to buy whole new assembly

I had a light like that, I didn't bother I just got one from a scrapyard.
I guess you could cut it open and see what has corroded.

Just a thought, have you swapped the bulb holders round? They get old and brittle, it might just be one of them that's failed.
