I am proud owner of a 209D year 1987 from my father’s estate. It is a van converted as a caravan. To the problem: the fog lamp does not work. Two lamps were mounted at the lower part of the rear bumper. The left lamp had no bulb at all and the plus line went to the right lamp and from there a white cable into the interior. Unfortunately there is a floor there so that I can not continue the cable. The cable is without spa nnung. Question: Is the fog lamp running over a fuse? Since I usually only see a fog lamp mounted on the left on most of the pictures of a T1, but in my case the cable is in the interior on the right, I assume that for whatever reason Father has moved the original line from left to right and then laid a bridge from right to left. If I don’t find the error, I will move a new cable and only install the left fog lamp. Connect the cable: directly at the light switch or is there a relay or another point in the front room so that I can save myself the expansion of the light switch? Thank you!
