My A/C, vent fan (blower motor) keeps going in and out. Does not do it all the time, but when it goes out, it will come back on after a few moments, but will not run full speed. If you try to adjust the speed, it just cuts off again. What is causing this.
View 7 RepliesThe blower motor went out on my 2008 F-350,? I can't for the life of me figure out how to get it out. Do I have to remove the dash? I am positive it is fried, I ran a hot wire straight to the motor and it still wouldn't come on.
View 2 Repliesmy blower keeps blowing even when i turn off the system, it does stop when the motor is off but comes back on once i start the truck...relay is fine.

The blower motor has quit. All fuses relays etc appeared to be ok. So I tested the connector going into the motor, I saw 13.9 volts so assumed it was a bad motor.
After removing the motor I bench tested it by connecting 12volts to one side of the connector and negative to the other. It spun up.
I re-tested the motor supply connector in the vehicle, it has 13.9 volts on the yellow wire, and 4.44 on the other. I adjusted the fan speed on the climate control, although the fan images on the display increased, there was no change to the voltages on either line.
I used the 13.9v connection on the positive terminal and a ground on the negative, the motor spins.
Is there a method for accessing codes that will display what is causing this failure?
So why do I have 4.44 volts at what should be a ground? Is this a bad resistor or is the climate control euchred.
Have a 2004 F-250 and blower motor speed 3 is not working..replaced resistor pack with Motorcraft part and everything works except position 3 ....
View 6 RepliesMy Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

Like the title says; I have a 2001 F350 with No blower Motor and Just Defrost, it is actually a friends, he is building a fence, and I am looking into the truck problem. The just defrost is probably a vacuum issue, but I do not have any book for this truck, so I have no vacuum or wiring diagrams. As far as the blower motor, I am thinking switch or motor, fuse has been checked? Is there any other "control" box involved with this year/model? Also any dash tear-out instructions, to make the access easier?
View 1 RepliesCurrently My AC / Heat blower motor operates but, speed 1 and 2 are the same, 3 and 4 are fine. I replaced the blower rheostat that is located on the firewall, but still no difference in fan speed.. A few years ago the blower only operated on Hi and the rheostat was the problem then.

loud deep rumble noise when turn on the blower. both heat and a/c. removed the blower and seemed to turn ok. blew out all vents. removed heater radiator cover, checked most flaps to see if working. doesn't seem to be obstruction invent. the flap behind blower clear and functioning ok.
When on second speed, almost sounds like blower motor is out of balance. if run on high for 1 minute, smell electrical burning! Think to replace motor will work? will post another issue with radio and power windows
I have and 07 F250 and the #2 speed for the blower motor don't work (hasn't since I bought it) I read that the most common cause of this is the resistor under the hood on the firewall so I replaced that and still no 2nd speed??? Where I look next? Motor itself maybe?

View 5 RepliesMy HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?
View 5 RepliesAbout 6 months ago I bought a 2003 F350 King Ranch to tow my toy hauler. Very happy so far. The one complaint I have is this...
The design of the heater / AC control module for this year of truck does not have a separate AC switch. There is not a separate button to turn the AC on and off and with a separate switch to choose which vent to blow the air through. For this year, I think 99-04, the vent selector switch must be turned all the way to the left and there are two AC Options... AC and Max AC. For both of these options the AC only blows through the dash vents.
Is there anyway to upgrade the in-dash unit to allow you to turn on and off the AC compressor while independently selecting, floor, foor / vent, floor / defrost, vent / defrost, etc... for the vents that the AC blows through?
I live in CA and it can get HOT... I would really like to blow the AC through the floor vents and / or the floor vents and the dash at the same time to provide more even cooling throughout the truck. Also, blowing through the floor vents would provide better cooling to the back seats.
My husband and I have 3 Excursions, V10, 6.0, 7.3 and I have a 6.0 250 crewcab. 3 of the 4 now blow air or heat from just the defroster unless your going at a slow speed.
View 2 RepliesI recently purchased a 2012 f350 power stroke. Love the truck but went out this morning and the air would only come out of the vents. I couldn't get anything out of the defrost or the floor vents? Truck is out of basic warranty so want to see if I can figure this out myself or if it needs to go in the shop.I've looked for a fuse but didn't see anything that ran an actuator door.

View 1 RepliesI have a 2000 f250 4x4 7.3 diesel. I had problems with my a/c and controls for sometime now. my a/c was blowing threw the defrost vent. I was told my blend door was bad. I bought a new blend door installed it,still doing the same thing. I was told to check my vacuum lines. I check them, they were bad. I replace my vacuum lines and my vac pump as well. that fixed my problem blowing threw the defrost vent. I can control my air flow from floor,dash vents and defrost vent. the problem I have, I not able to control my temperature when I turn my center from red to blue. It blows hot air and the air that is coming out of the vents isn't very strong at all.
View 1 RepliesI have a 1999 F250 V10 SuperDuty. Just recently I had noticed some gray foam material laying on my passenger floor. Then about a week later my air vent near the passenger window is whistling really bad when I have the air on. I normally have that vent closed. Is there an easy fix for this? My guess is that the foam inside has deteriorated and broke apart.
View 2 RepliesThis is something to check, I found the vent line pinched closed on my 2000 F350 when I was trying to find out why it was leaking. When I was under my 2013 installing the hitch I checked it and found the same problem. The clip doesn't pinch it closed right away but it will happen if you don't move the clip.
View 8 RepliesI have a 2012 F-350 SRW with a 6.7 diesel. The other day I went to push the defrost switch and noticed it does not work. All the lights work in the switches, and the temp control works, but no matter what I push, defrost or floor, it stay in the vent only. Anything I can check??
View 1 Replies2011 F350 loaded. Stuck on vent mode. Found actuator can feel it trying to move but something is stuck. Tried to remove the actuator but not enough room between the motor and a steel bracket welded in to the dash. (Not removable). Do I have to remove the dash ? (I suspect something fell inside and is stopping the big vent door from moving as i did pull the motor far enough away to move all the door except the vent door.
