For some reason, the left blinkers no longer come on. I have check the bulbs and they are good. I replaced the fuses the other day and cleaned all the fuse holder contacts.

The right blinkers do come like normal. When I turn on the right blinkers, the relay works like it should. I removed the black relay cap and can see it operating properly. When I turn on the left blinkers, the relay does not work/move. The light filament in the bulbs are not on either.

Is it possible for the relay to only work for one side of the car? I figured the relay either worked or didn't work. Attached are two photos of the relay internals. The one post with a "C" designation appears to have gotten hot at some point and wonder if may be the issue.

Anyone know what the connectors are on the relay?
C =
49 =
49a =

If I were debugging this, first thing to do is check that the bulbs are ok by swapping them in the right side and make sure they light. Then check the grounds on the front and rear left side turnsignal buckets.

You can do a cursory check of the grounds by turning on the parking lights. This should illuminate the low power filament in the front bulb, and the low power filament in the brake bulb. Also check the brake light on the left side. It uses the same ground as the turnsignal.

If the parking lights work, then I would start by disconnecting the battery negative lead, drop the fuse panel and pull out the hazard switch.

All the exterior turnsignal lights terminate (or start) at the hazard switch. Since the left turnsignals front and rear aren't working, likely the issue is at the common point of the wires which is at the hazard switch. See the schematic above. The left turnsignal wire is Black w/white stripe and connects to the L spade. The spade is marked on the switch. Make sure these are all connected and no exposed wires are touching anything.
