When to replace the blower motor resistor on a Ford Explorer?
When to replace the blower motor resistor on a Ford Explorer?
If your multimeter still does not show continuity for those particular blower resistor pins (you’re testing) then this test result confirms that your Ford Explorer’s (Ranger, Mercury Mountaineer’s) blower motor resistor is bad and needs to be replaced. CASE 2: The blower resistor passed all of the continuity tests indicated above.
How can I Fix my blower motor resistor?
Purchase an upgraded pigtail and splice it into the harness along with a new blower motor resistor. Conduct an amperage draw test at the same time to rule out excessive current draw from the blower motor. Car makers design their HVAC systems to reduce the possibility of debris getting into the system.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
How to test the a / C heater blower motor?
How To Test The A/C Heater Blower Motor (Ford 4.0L). The component that makes it possible for the blower motor to run in the 3 speeds lower than HI is the blower motor resistor assembly. If you have already removed the blower resistor assembly from your Ford Explorer (Ranger, Mercury Mountaineer), you know that it’s made up of 3 resistors.
How to replace 06-10 Ford Explorer blower motor resistor?
Step by step tutorial how to fix your climate control if it blows only on high highest setting. In this case Blower motor worked only on number 4, so replacing a blower motor resistor fixed the problem. Procedure is capable with 2007 2006 2008 2009 and 2010 Ford explorers with manual climate control knobs. Also fith Mercury mountaineer Hey guys!
Purchase an upgraded pigtail and splice it into the harness along with a new blower motor resistor. Conduct an amperage draw test at the same time to rule out excessive current draw from the blower motor. Car makers design their HVAC systems to reduce the possibility of debris getting into the system.
Why does my Ford 4.0L have no blower?
There’s a good chance that what’s causing the ‘no blower’ problem on your Ford is a bad blower resistor or a bad blower switch. Altho’ it’s beyond the scope of this tutorial to diagnose these components… you have at least eliminated the blower motor as bad.
What to do if your blower motor only works on high speed?
If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode. To repair the problem, simply replace the resistor block. It’s usually located in the ductwork (to keep the coils cool) below the glove box.
Where is the fuse on the Ford Expedition blower?
I replaced a 40-amp fuse in the power distribution box under the hood and a 10-amp fuse in the panel under the glove compartment. I also replaced a blower motor relay in the power distribution box. I bought a new blower motor. I plugged in the wires, but I didn’t install it yet (It’s in a tough-to-reach spot).
How to test a Ford blower motor switch?
Basics Of Troubleshooting The Blower Control Switch. TEST 1: Checking The Continuity Of The Blower Switch Fan Speeds. TEST 2: Using A Jumper Wire To Bypass The Blower Resistor. Where To Buy The Blower Switch And Save. Related Test Articles.
Why is my blower motor switch not working?
Double check that you’re testing the correct blower switch terminals and retest. If continuity is not present where indicated in the test steps above and this lack of continuity coincides with the blower fan speed that’s not working on your Ford Explorer then you’ve found the cause of the problem.
