This has been an issue with all 80's and early 90's blowers. For the 124's they had a service bulletin to move to an outside the fusebox strip fuse which they mounted on the drivers side strut tower. It was like a silent recall. If you fuse blew they put it in. In 93 on most it was just standard. Its like a 40 dollars kit from MB for 124's, may be a direct fit for others.
