Ford F-150 (2009-2014) :: Blower Motor Stuck On High
Oct 9, 2011
What is the testing procedures for the blower motor controller on my 2009 150 Lariat. In the old days it was called the resistor but now it is computer controlled for the dual climate control. My fan is stuck on high, the fan switch does work(the bars on the display change when I push the fan speed button). The climate control works also, just blasts you with air and the temp is changing a lot due to the fact of the fan on High. I am 99% sure it is the blower motor controller, but I would like to test the controller.

I replaced the blower motor resistor on a 2010 F150 with dual climate control where the blower was stuck on high.
After replacing the resistor, now the lower speeds work fine, but when placed on high speed, the fan completely shuts down. Replace with the old resistor, and it only runs on high.
How to proceed, or what else might be the problem?

Have a 2009 platinum, 5.4, supercrew with dualzone heating and air. The blower motor resistor block is overheating and melting the connector block. fooled with it way too much, and then put a new resistor and pigtail in it. The new resistor would kick out in about 30 seconds, so used the old resistor on the new pigtail, got hot, melted the new pigtail. What is causing the resistor block to get so hot, and what do I do about it?

2011 FX2, 81,000 miles, with dual control A/C. The blower motor works fine on speeds 1-5. Put it on speed 6 or 7 and the motor trips after about 5 seconds. Turn it back below 6 or 7 and it starts working fine. I have replaced the resistor and the blower with the same results.
I have read through a good deal of the posts and most seem to deal with the resistor and the lower speeds not working. It's like its tripping a breaker or overload.

My blower motor does not blow hard on high. 2009 AVALON.

Well my blower motor only blows on high which IMO points to the resistor, went and bought one and still only blows on high. Tried to test the plug that goes to the resistor but couldn't get anything, shouldn't there be 12v going to the plug and then step down to the resistor until high is selected then 12v bypasses the resistor all together? Blows strong and cold, too cold actually since we cant turn the blower down so we have to turn it off for a few minutes.

My 2010 Expedition Limited AC seems to be stuck in the highest fan speed setting. Changing the setting on the panel control do nothing to change the speed. But you can adjust the temp and it will respond. It is a dual control unit. When I try to turn the system to off completely it will go to what I believe is the vents and stay on full blast. If I turn the truck off and on again the whole system remains off until I turn it on again. The only way to turn it completely off is to turn it to off mode and turn the truck off.

I have an 02 Santa Fe and last night while driving the fan would not turn off. It also started switching speed by itself.

I recently bought a 96 ranger.I noticed the fan did not work but for high. I search the internet and found how to remove it and discovered a mouse nest(village) which basically took over the housing where the evaportor core,blower motor resides. I bought a chilton but cannot remove the housing around the core so I cleaned it the best I could(air compressor and vacuum and disinfectant)...
I had to buy a new blower motor and resistor. However, I cannot find the hose that attached to the blower motor?-mouse had chewed a hole in the one- I've looked and found serveral differents names for it but seems I cannot find it at my local parts store.
My question is- is this intake hose? vent hose? I'm guessing I will have to go to dealer or, if I know the name I can look it up in a salvage yard?

I don't know if its a coincidence but it rained hard all weekend and went to work this morning to find out the blower motor only on 4(high). I checked the plug going into blower motor and it looks dry and clean. is there a common occurrence with this? What to look for?

I bought my youngest daughter a used 2009 Ford Escape (out of warranty) a week ago. Manual HVAC controls, 3.0 V6, AWD, 73K miles. The HVAC blower motor do not seem to move any air on speed 1 and 2. However speeds 3 and 4 appear to operate normally. Speed 4 noticeably puts out more volume of air then 3. Each 3 and 4 operator what seems to be normal speeds for their setting.
I would normally suspect resistor but my experience is usually that you have all or nothing not it's partially working like this is. I don't mind throwing a new resistor in there and trying it but I rather come up with a better way of troubleshooting it then throw parts at it.

Went to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.
Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.
Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.

I have a 2009 Camry SE. Yesterday it would not crank and I wound up having to replace the battery. Now the ac blower motor runs even when the ignition is off and when the ignition is on, I cannot control the speed of the blower. I had to unplug the blower motor to make it stop. What would cause this?? Everything else seems to work fine.

I have a 99 F150 4x4 with the 4.6 Motor approx 150000miles. Transmission went out so I decided to try and replace it...
New/rebuilt tranny went in with no problem but something is not right. It will drive but seems like it is stuck in high gear and bogs the motor down. It is giving me error codes P1747, P0750, P0755, P0743, P0102. All the wiring harness is in good shape with no burns or other noticeable problems. Somehow the transmission isn't reading right?
When I bought this rebuilt transmission I was told it was set up for 2wd but he would convert it for 4wd. The only difference i noticed with the new tranny is the shaft coming out of the tranny, where the safety neutral switch is, has a diamond shape instead of the oval shape that connects the shifter cable. No big deal i think, just had to buy a new link for the shifter cable with the diamond.
Also on the passenger side of the tranny there is a nine pin plug. My wire harness from the truck has one pin hole that is opposite of the tranny. Not sure why. Do I need a new harness or wrong tranny?

Started up today and no response from the A/C fan on any speed- dual climate control. Checked all fuses good. Electronic control panel shows normal with all the fan speeds, but no blower motor action.
Is it the motor or a resistor/controller? Thought with a bad resistor you would get the fan on at least in one speed.

My blower on my 2010 Lariat truck isn't working and I can't seem to figure the issue. No heat or AC. It seems that some air is coming through, and the fan indicator shows it on high, but nothing.

My fan is NOISY!!! Its noisy in AC mode, defrost mode, heat mode, vent mode.... It really sounds like a leaf got sucked in. I don't wanna mess with the dealer since I don't think its a warranty thing. So, is it as simple as dropping the glove box and three screws for the blower as I have read?

My blower fan will not run on setting 1. on 2 3 and 4 it will work but not on the lowest setting. I replaced the relay and it still doesn't work. I have a 2010 f150 with the 2v 4.6 .....

Was 7 degrees F out this morning. Went to turn on the defrost and heard this: (may need to turn up audio a bit)
2013 F150 HVAC blower noise in cold temps - YouTube
There was some snow/ice buildup under the "grate" that sits above that I imagine is the air intake for the blower. Hoping that it was just Ice buildup that will thaw out.
I ended up having to turn it on because the condensation on the windshield was becoming a safety issue when I drove into work. Motor made quite a high pitched wine. Better that than slid into a car.

In the last few weeks I have noticed that when I have the control set to floor only (manual system, not dual) I still have more air going to windshield than the floor. I can switch to Windshield/Floor, Center Vent and all seems ok. Just when in floor only it seems to keep going to Windshield. Asked the service rep at last oil change and he said it's normal for some air to always go to the windshield/defrost. I'm going back to dealer and check a new F150 XLT to verify I have a problem.
