Auxillary A/C Fan

[L.D.Cosby]

Hello All

I 'm trying to troubleshoot my auxiliary fan on my '92 240. I don't have
any voltage at the connector of the fan. I'm not sure where to look next.I
have noticed their are several relays in this circuit. Any advice on how to
troubleshoot this circuit effectively.

Thanks
Larry

Make a long jumper wire and put battery and ground straight to the fan
motor. If it works then it is a problem with the relay or fuses.If the
compressor clutch engages it is most likly the fan motor.
