The cab fan will not turn on. I have 24v at the plug, a solid ground and I can watch the voltage go up in increments on the signal wire as the fan speed knob is increased.

Any ideas?

Deere I assume? Machine serial number?

An "L" might be under warranty.

Do you have voltage at the P033A Red wire? If not, then check the F33 blower motor fuse. That would be the center fuse box in the right side compartment under your right window. Also, check the V10 diode. It is next to the center fuse box. It should be to the right of the fuse box. If it is blown, then make and install a jumper. The diode is not needed.

Thank you mg2361. I’ll heck that diode this morning. I had power everywhere I was suppose to and the fuse was good yesterday.
