Ford Excursion :: Blower Motor Only Blows On High?
Jul 2, 2012
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.

Thought for sure that would fix my fan speed, but nope. Replaced blower control module, Still only blows on the highest setting. Didn't try running it on auto, but that's what it did on manually turning the speed up. What else could it be?

Having a problem with the blower speed. Only blows on high. As soon as you move it below max it blows very little like its on low nothing in between. What could cause that?

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.

My blower motor runs with the key out on all speeds in my excursion. Replaced blower relay in hood fuse box. NO FIX. As I move climate selector to off and turn key to acc. and off it will turn off the blower. If I turn the selector to any position such as vent or heat with the key out, blower runs thus drains the battery. Do I have to replace the whole climate pod?

I have a 2005 Eddie Bauer 4X4 with the 6.0 and Automatic Temperature Control. I need a new blower motor control module, and have been confused by what I have been able to find online. What is the full Motorcraft part number, or other information so I can get one.

It started with the blower motor that wouldn't turn off by itself when the truck was turned off. I forgot to turn the fan off one night and woke up to a dead battery. Got my dad to come give me a boost and it would turn but not start and the anti theft light in the dash was blinking fast.
Later in the day I got another boost and it started right up.
This was yesterday... after the last boost and startup I went and got a few things, stopped to get gas... started back up fine each time.
Last night I was greasing zerks and making sure everything in the front end was nice and tight when the abs module started clicking... and the anti theft started blinking and truck wouldn't start. Left it alone and went to bed.
This morning I boosted it and it started fine. Later in the day it wouldn't start again because of the anti theft. Gave it 5 minutes and it started. Stopped to get gas... wouldn't start (anti theft)... started after about 5 minutes.
On the way back home... it's been making this 5 beep, pause, 5 beeps, pause sequence so I pulled it into the garage and turned it off now the locks are locking/unlocking by themselves randomly, the beeping is on and off, anti theft light blinks for a few minutes then goes away only to come back...
I've been told to remove the fuse box under the hood and check to make sure all connections are clean... I've searched and seen possible solutions ranging from a dirty connection to needing a new GEM module and apparently sometimes just a low voltage situation will cause our trucks to act nuts...

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 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?

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.

About a month ago I replaced my blower control module. I purchased the module from Rockauto. The first replacement module lasted about a month. I received a replacement because the blower stayed on high and wouldn't turn off. The second module only last one week, the blower once again only blows on high and won't shut off. Both replacement modules were made by Dorman. Could something be killing them or am I just getting crap parts?

My blower in my truck only blows at levels 3 and 4. Do the blower motor going out? Switch? Motor relay? I've read a bunch of things try?

There used to be a audible pop in my stereo speaker when my heat would kick on. Now there is not. My heat did this last winter around the same time. I checked Fuses. The blower blows, but it just blows cold air. It could be a thermostat, or a clogged heater core. 1997 Ford Ranger 2.3L ...

The ac/heater works just fine. But the air only blows from front vents towards face; even if i press button to defrost or floor or frontnfloor.

Recently got a 2003 f 250 6.0 that has had a little work done on it. Absolutely love it with 1 exception. When I turn on the ac or heat It blows a 10 amp fuse that goes to the blower relay. It was occasionally now it's all the time.Blower ok, fan speed resistor ok. What or where to look.

I have an '02 F150 XL. 200k miles. My a/c blows cold, and I have every fan speed, but it just doesn't blow very hard. I replaced the blower motor thinking that would work, but that did nothing. I've been told to clean the evaporator core, but I don't know where that is. How to do that, as well as any other part causing the problem.

I have a Full Size 93, 5.8L Van. The blower motor has stopped working. I have checked the fuzes, ok. I have checked the Power Distrubution Box, ok. I do have power to my Aux (rear) blower. I have hot wired my blower motor, it works. I have no power to the blower motor, thermal limiter, or to the fan control switch on the dash. (Like I said, the Aux on the dash works). What else is there?

My 92 F-150 my heater blower motor doesn't put out enough air like my 2003 Lightning blower motor does.... So I figured after all these years that I would put a new heater blower motor in, well it's the same hear output and there's no debris in the heating ducts and the cable lever is working fine to close the blend door, so I guess maybe it's normal for these 92-96 F-150 trucks to have mediocre heating output ;-( Is there a bigger motor I could put in to get more heat..... The resistor is fine to, it works on all speeds.....

My mom has a 1988 350 Econoline van chasis that is a motorhome class C.
The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.
I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.
I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.
