ACTION REQUIRED

The arc suppressor is located directly behind the overhead panel in the cab. (see Figure 1). Remove panel to gain access to the arc suppressor.

In "Before" failure instances, replace 189-3158 Arc Suppressor with a 9U-3672 Plug Assembly. In "After" failure instances, completely remove (cut) damaged connection from the harness and rebuild using 180-9340 Connector Socket, 155-2269 Connector and 155-2261 Plug Lock. Then, insert the 9U-3672 Plug Assembly into the rebuilt Socket Assembly.

Replace panel and check for HVAC fan functionality at all speeds.
