I have a regal gran sport sedan 3800. The left rear turn signal is not working. I checked the 4-ways snd they work fine. Changed all bulbs in the rear and still nothing. Is there a switch or module I need to look at or could it just be the flasher?

Did you check voltage and ground at the bulb socket? Sometimes the bulb doesn't make good contact. Could be problem with multifunction switch?

The 4-ways are working so I ruled out the socket.

I'd have to get at the turn signal switch, yellow wire carries voltage for left turn rear. If there is air-bag in steering wheel, there is a safety issue. Safety is your responsibility. You will have to disarm the air-bag first, even then?

No airbags. So it is most likely the muliti. switch in the column. .
