A/C Fan Relay for 86-92 Vanagon

A/C Fan Relay for 86-92 2.1L Vanagon. This relay is found in the left rear pillar on the 86-92 Vanagon.  There are three relays in this location, but this is the tallest one and has the number 13 on the top.  That is appropriate as this is the unlucky relay on the van.  It will go bad and cause many different problems with your AC system.  The problem usually manifests itself as "missing" speeds of the rear AC fans.  If you are having issues where your fans only work on certain speeds, or other funky electrical problem with your air conditioning, I would replace this relay first.
