'89 900 (NT) Radiator Fan Doesn't Get Voltage. Thermal Swi..

External Since: Apr 17, 2006 Posts: 3

I just did a little troubleshooting and found that when the fan was
connected directly to the battery it works good. The thermal switch
was bypassed and is not the problem (there is no voltage getting to
this switch). The 30 amp radiator fan #25 fuse is getting 12 volts. Any
suggestions on what other things to check for is greatly appreciated. I
may just hook up the fan directly to the battery via the thermal switch
and install an inline fuse.

Have a look in schematics to find out why the fan isn't getting power. It's
probably a broken wire, connector that's come loose, or something similar to
that.
