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?

With the "C" it sounds like you have a 74+ car.

The "C" ("K" on earlier cars) feeds the indicator in the tach. 49 is power in, and 49a is power out to the turn signal switch.

Thanks - yes I have a '74 model

I would replace that relay. You can probably use one from a VW

Well, from what I have gathered from others is that the relay either works or doesn't.

Power comes in to the relay via pin 49, and exits via pin 49a. The C pin is to the dash indicator and the 31 pin the ground. The turn signal lever controls which side the power goes to (right or left blinkers). Thus it appears I have an issue at the signal lever or at a turn signal.

The identification above is what is at each pin on the relay.

It looks pretty weathered. The headlight relay in my car worked sporadically, sometimes I could get high beams, sometimes not. New relay fixed it. Got the relay and a new gas cap at the local VW shop.

Good idea on going to the VW shop for a good new one. Have some tests to do when I get home. Thinking my signal switch may be the culprit.

Wow,so amazing tool,Maybe the best one left blinkers is that.
