Fan Blower Switch or Fan replacement

Kurtis22 · Feb 8, 2020

Blower or switch is bad. Trying to figure out the issue by tomorrow morning. Its a snow plow machine and snow is on its way for Southern Minnesota. Has anyone replaced theirs? Any insight would be appreciated?

Did you check the #7 fuse that is under the operators seat?

If you are sure is the switch, put a temporary jumper across it.

The service manual is pretty vague on troubleshooting. Pull the panel where the switch is located. You should have power on one wire when the switch is off. The manual then says that power is fed to another terminal when L-M-H is selected. Power is also fed to the individual LMH terminals for a total of 5 terminals. If you switch has power and seems to be working, check power and ground at the blower.
