Interesting Electric Fan story for all of you. My wife (gf at the time) drove a 1987 VW Cabrio for many years in Michigan. The car was in an accident where the front end was smashed in and repaired. Years later in Michigan still the car ran and drove fine.

Fast forward a few years to her living in Chicago. She's in traffic and the car is running hot, but not over heating while crawling on the Kenneday expressway. Fan kicks in and cycles as normal but still runs hot. Trying to figure out what the issue is, we decide to replace the old decrepid radiator.

after another traffic stint, the car still is running hot and with similar pattern as before.

While the car is idling and I am bent over the front end looking at the fan, it kicks on and I notice hot air blowing on my legs and realize the numb nuts who repaired the car years earlier, plugged the fan in backwards.

All the years of cool Michigan summers was masking the real issue of the fan running backwards. At highway speeds it didn't matter, but in traffic it did. Switched the fan wires and never had another problem.
