Fan In F150 Only Works On High

I have seen some of the postings where they think it is the blower motor resistor.

Rechargeable fan in india. However most car makers bypass the blower motor resistor completely when you move the fan speed switch to high. I have a 2010 ford f150 over the past year the ac heater blower has gone from working on all levels 1 thru 4 to just working on high. All you need to do is to replace the resistorford part number.

With that said if the blower motor doesnt work at all its also common to find a defective blower motor relay. This happens very often to ford pickup truck or suv. You can verify this in the ford f150 blower motor diagram below.

If your blower only operates on its highest speed chances are you have the series type of blower motor resistor. I have the acheater blower on my 1996 crown victoria only works on 3 high. The temperature control works fine.

4l3z 19a706 aa or napa part number. 1994 ford f150 blower motor resister replacement to fix a blower motor that only works on. This is the most common failure mode.

Blower fan runs high only on 2006 ford explorer if you have manual control climate control then the system has a blower motor resistor. If you find this video useful venmo beer money to atsteviecarssuck. I had this problem on a 1993 jeep cherokee and it was the.

Most commonly the fan will only run on the highest setting. In other designs the failure of 1 resistor means you lose only one speed. Note that the interior fan circuit contains two relays in the same way that it contains two fuses.

If you have automatic climate control then the system has a blower motor speed control. My question is could it be the blower motor itself. The 2004 2014 ford f 150 with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings.

At the time i thought the problem must be something else then since it still worked the same as with the old resistor. Depending on the system you have buy the part and then look under the dash for like part you will. But i have since learned that the resistor is bypassed on the high setting.

This is a well documented problem and is caused by a failing blower motor resistor. This video highlights a common issue found on 2011 ford f150 pickups with automatic hvac systems when the blower fan speed becomes stuck on high speed.
