RE: [DML] Re: Fanzilla Failure???

["Joseph Kuchan" <josephkuchan@xxxxxxxxxxx>]

Jumping the otterstat sends a signal to the Fanzilla as if the car was hot. 
In response, the Fanzilla should sequence the fans on. Jumping the otterstat 
is just a convenient way of simulating a hot car so that the Fanzilla will 
attempt to operate the fans. Since one fan does go on in response to jumping 
the otterstat, we know that the Fanzilla is seeing this "signal". If only 
one fan operates, there are a few things that could be wrong:

1. One of the fuses in the Fanzilla could be blown. (But you checked that 
and they both seem to be okay. To be sure you can swap the Fanzilla fuses in 
their holders to confirm that just one fan comes on. If it is the SAME fan, 
then both fuses are okay. If it is the OTHER fan, then one fuse just LOOKS 
good but is actually blown.)

2. The Fanzilla could have an internal failure.

3. The wiring to the non-running fan could be bad. (Open)

4. The fan itself could be bad.
