Where is the blower motor module located on a Kenworth W900?
If you’re having blower motor speed issues, the resistor module that controls it can be found inside the cab on the passenger side, below the dash on the right-side behind a cover. It’s fairly easy to replace! (07-15-2015, 07:46 AM)Moonlight3 Wrote: I am looking for an air conditioning system electrical diagram for a 2009 KW W900.

Where are the a / C switches on a Kenworth W900?
This is located inside the blower housing on the firewall, passenger side. After the power leaves here, it runs to the A/C compressor high-pressure switch.

When to use high or low fan speed?
There is no single “right” fan speed for all heating and cooling conditions and both high and low speed settings have uses and advantages. Higher air speeds are needed during the cooling season than during the heating season.
