1991 Mazda B2200 truck . Left rear turn signal only doesn't work no power to it front works Any suggestions. need wiring diagram?

Answer 1

I have had the same issue and it is not a wiring problem persay.It is the contacts inside the bulb socket making a crappy connection.I suggest buying a new set of contacts sold at advance auto parts,auto zone and replace the unit it has the two wires,round flat bottom the bulb sits on and spring.Or you can replace the whole plastic socket too offered at both stores as well,cost a little more.This will fix the issue.I had the issue on the front signals sockets were just worn.If you replace this and still no power checking with a test light then it is a wiring issue,but think it is the socket terminals are possible broken and by changing this should correct it.
