What to do if your New Holland heat blower is not working?
Go figure. The fan switch ( the rotary switch ) is likely where the problem is. If you have 12V to and from the fan switch, check the wiring harness to the fan and check the fan motor windings for continuity and to see that they are not grounded. Also rotate the fan motor shaft by hand to be sure that it is not seized.
How to know if you need to replace a heat blower?
You can check it with a multimeter but it might be easier if you checked to see that you have proper voltage (12VDC) at the fan (with the multimeter). If you do, remove the fan and attach it to a known 12V source and see if it will turn. If it won’t, replace the motor. If you don’t have voltage to the fan, check the fan switch.
What should I do if my blower wont shut off?
If the blower stops with either of these steps, the problem is in the HVAC control module. However, if the blower continues to run at high speed with either of those tests, replace the blower motor control processor. Just as an FYI, the retail price of the blower motor control processor is $280.34.

Options for repairing it yourself and saving big $$$. If your heater motor won’t come on, first check your fuse or relay. If you are not sure if the switches are the problem, we recommend you get the covers off and power the motor directly with a 12 volt power source.

What should I do if my Jeep Wrangler blower is not working?
Jerry – You had mentioned that if the blower fan simply didn’t work at all you should look into replacing the switch plug. I have replaced the switch and the resistor and still no fan. Both of the fuses (behind the glove box and under the hood) appear to be working. Where can I find the blower fan to test it? Newbie Jeep owner here – 2000 TJ w/2.5.
