"Why is my turn signal not working?" için yanıtWhy is my turn signal slow and needs to be tapped to flicker continuously . I have a W123 250 Auto straight 6, and had the exact same issue with my flicker unit as Takuya. After reading Takuya’s solution, bought a bottle of methylated spirits, after removing the Unit(No SAEJ590C/J945) DOT QC76 from the car , I removed the light shaft . Poured the methylated spirits into the opening of the light on the shaft which I removed, and repeated the same process a few times… , grab the hair dryer to make sure the unit was dry and bobs your uncle -the unit is a good as new :) Thanks Takuya for your advice, saved me a few bob.
