Not only is the fan motor different, so is the harness, resistor, and
control methods. With the smaller motor, the fan switch actually has the
motor current going through it on low speed. The high speed turns on the
relay on the fuse box. With the larger fan motor, the low speed switches the
relay on the fuse panel, (same as high above) and high speed is done with a
separate relay mounted above the fuse box. It is hat big white relay with
the fuse link.

For some reason many 90 and 91 went back to the smaller fan and control set
up even with AC.

Subject: 88 Vanagon radiater fan issues

Hello, I know a fellow that has a 88 Vanagon where the fan dosent come on.He
has A/C . The fan is a different part number than the  common fan is most
vanagons. I understand that VW changed the fan for vanagons  that had
a/c,after 1986.Interestingley, yesterday,I took a fan off a 90 w a/c and it
was the same fan as my 85. Whats up? I was expecting to find tha fan updated
,for the a/c this van had. Also his fan seems to draw to much current.It
almost melted a papaerclip that used to jump the temp sensor ontehn
radiater.Is this normal? Thanks
