The resistor is already conveniently built into the inner wall of the blower fan housing. • METHOD 2 (Single Speed Connection): If you prefer to connect only one wire (Red, Yellow, or Blue) for a specific speed, that is fine too. However, please note that you will need to add an external resistor to control the fan speed properly. 📌 VIDEO CHAPTERS: 00:10 John Deere 4040 Cabin Blower Motor Symptoms & Diagnosis 00:38 Install the Aftermarket Blower Motor & Comparison 01:15 Modified 3-Speed Blower Motor Unboxing 03:59 Test the Tractor after Replacement #fridayparts #blowermotor #johndeeretractor #diyrepairs #tractorrepair
