81 gsl turn signal issue
 

Hey all I have this weird issue with my left turn signal. First off, I replaced all the bulb on the left side. Alright, so when my headlights are off my front left signal light blinks fast and the rear does not work at all. When my headlights are on neither the front or back work on the left side and the left arrow on the dash is always lit. Right side has no issues. Also, the release to turn the signal off after a turn does not work on left side, again right side has no issues. I used dielectric grease as well after I replaced the bulbs. Did not make a difference.

Bump. Please help. I don't want to get pulled over and nobody takes my hands signal left seriously and they always honk and freak out. Would it be smart to order the plunger and cpu? Or get the whole turn signal assembly? Nobody has had this issue?
