Suddenly, one morning, my E320T started an erratic operation on its turn signals. They would come on when engaged for a few seconds and then go dead. Same happens with the hazard lights.

Changed the fuse and check all bulbs to be on the safe side, but it did not solve the problem.

Sometimes when the I engage the turn signal and they are dead, when hitting a pothole on the road they will come on for a few seconds and then stop working again.

Any ideas or suggestions on what to look for???
Thanks in advance.

On the 1995 E320T there is a "combination" relay that controls this operation, MB part number 201-821-02-47.

Thank you so much the advice!!!

I thought there ought to be a relay somewhere, but I wasn't sure.

That is why this site is so helpful!

Thanks again.

I just ordered this part from FastLane a few months ago. I don't know about yours, but in addition to blinkers & hazards, the relay on my C280 controls the rear defrost, and the intermittent wiper. It's nice to have all working again.

Part is cheap here too! $150 at the dealer, $50 on fastlane!
