John Deere 4430 Left Side Electrical

ebook · Jul 23, 2018

I'm having an electrical issue on my John Deere 4430. The AC does not turn on, the left blower doesn't work, the left wiper, and the radio (so generally the left side and the radio). Is there a place I should check first? Thanks for any thoughts!

The ac power goes from the fan switch to the cold switch then down the right side in the Yellow wire to a plug over the right battery then up and out to the right front of the radiator still using the Yellow wire,,The radio powers from the accessory relay wire and should power up when the fan does,, a bad fan motor or switch could be the start of your search..The plug above the right battery can get in nasty shape also and be a suspect spot ..

I will check those things. I did just take a look at the circuit breakers and the top right one was broken in half ... if that could be an issue?

Be sure to check all nuts on circuit breaker board for tightness as over time the nuts have been known to get loose.
