Re: [DML] cooling fans

["DMC Joe" <dmcjoe@xxxx>]

Brian,

The problem is probably at the fan fail module socket, fan relay socket, or
the circuit breaker. With the cool fan switch (otterstadt) jumped, check and
see if you have 12 volts at the heavy brown/orange wire leading the blue
socket.

Let me know the result.

Here are the answers to your other questions. The cooling fans receive
ground through the wiring harness.

The fan rotation is such that air moves from the front of the car to the
rear.

12V cooling fan power is supplied through two separate feed wires which are
part of the front wiring harness. We have no record of any type of failure
with this wire.
