Turn Signal Works but Running Light Doesn't - What Could Be the Issue?

While we are on the subject, has anyone experienced a similar issue but noticed it only happens when it’s colder outside? That always baffles me.

I’ve had that comment before! It can be related to relay malfunction due to temperature changes. Make sure to check the relay as well.

I appreciate everyone’s insights! It’s really a puzzle trying to diagnose these electrical issues. Starting with the basics like bulb and fuse checks is such a good foundation.

Absolutely! And don’t stress if it feels overwhelming—sometimes it’s just a simple fix that makes a world of difference.

To add on, be careful when handling wires as old electrical systems can be sensitive. Always disconnect the battery before troubleshooting the wiring.

Good point! Safety first, right? Plus, if you forget, your car might get a little shocked back to life—literally!

I wonder how common these issues are. Electrical problems seem to vary by model. Has anybody here dealt with this on different types of cars?

Interesting question! I’ve seen it on various models. Each car can have unique quirks, so it’s essential to consult the specific repair manual too.

I think it would be useful to document all our fixes and share them. Might help someone in the future not feel as lost as we did! Just a thought.
