on a 86 300sdl the blinker will blink 2-5 times and then stay on.
Next time it will work again for 5 seconds. Have been told to clean the hazard switch as it is part of the multi purpose relay #201 821 0247 setup and that corrosion there might be the culprit. Nothing worked. I hate to pay $151 for a new relay to find that it was not the cause of trouble. As far as I know it cannot be sent back even it if was used for only a few seconds. M-B will only tell you to bring the car in, and for mucho dollares.
Any thoughts out there???
