Ok, I have had this problem a couple of times before, generally when it is wet and cold outside and the result is a very dead battery. The heat/ac blower fan continues to run after the truck has been shut off and the key removed. I believe that it even comes on after the truck has been shut off. What could be causing this?
View 14 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 Replies15 f350 gas xlt with 8.6 Western proplus straight blade. I noticed that while only applying throttle and fully angling the plow ,the hvac system turns off and then on again and the dashboard lights also turn off with the message system also going blank. I've brought it back to the body builder, twice, that installed it and they don't acknowledge a problem. The only answer I got was it's probably a bad battery. The funny part is you can angle it all day while it idles but as soon as you apply throttle and fully angle it left or right it cause the loss of power to certain accessories. When it does this it also causes a relay to click under the dash panel on the drivers side .
View 8 RepliesMy 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 RepliesI have a 2000 F250 and the blower motor stopped working, the a/c clutch locks in but the blower will not run. I back tracked and I have no power at the motor or the resistors, or the speed switch. There has to be a relay that is turned on by the a/c selector to power the blower circuit. I guess my question is need a schematic of the a/c circuits? Or the location of the relay?
View 7 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.
Only 2 speeds of the 4 speeds are working on my blower. I was thinking it may be the switch, but someone at the shop told me to replace the blower resistor first. I did that and still only have 2 speeds. Im guessing I need to replace the switch now?
Also, I am having problems with my heat adjustment. I have it set to warm (half way between cold and hot) and out of the blue it will start blowing hot. I turn it down all the way to cold until it blows cold air and turn it back to warm, and it will be fine for a few minutes and start blowing hot again. Vacuum problem? blend door problem? How would I go about trouble shooting this problem?
My blower doesn't seem to blow very hard. I've been in other fords and the ac and heat blows great. Someone suggested that that I pull the fan motor and clean the blades.

View 2 RepliesMy 2001 f350 a/c blower works better on a/c compared to max a/c . When I turn the selector to max a/c it makes more of a blowing noise but less air blows out of the vents though. When I select plain a/c it makes less noise but blows more air out of the vents. What is wrong and how to go about fixing it is 93 here today and won't get much cooler over the summer months .

I bought a Motorcraft YH-1670 blower switch, but can't figure out where it's located?
I looked behind the glove box, but didn't see it there. I did not remove the screws to the cover behind the glove box because I wanted to first confirm where the switch is located.
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.

Blower is not working, but LED fan speed on dash shows it is. I've check all fuses and they are okay. This is dual-climate control, and neither works.
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 Replies1999 F250 .. Blower works some times then for no reason stops. When it works, I have all speeds, it makes no odd noises. I shut the engine off and then it does not work. I have power to the blower motor even when it is not working. I doubt it is the speed resistor module because that is not used in high speed. I've taken the blower motor out of its housing and pulled the resistor module as well. I find nothing wrong, power it up and the blower works. I put it all back together and it does not work.
View 4 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.
View 3 RepliesMy dad has a 2000 f250 4x4 with the 5.4. he said his blower would only blow on high. I told him it was his blower motor resistor. i thought it was under glove box. he took it apart and said no but there was a little box thing with wires he took off anyway and put back on. I then told him it was under hood below a/c lines. he replaced old one with a new one from auto zone and replaced the pigtail( plug too) fan works on high and a little bit on low very very little when u switch it to medium it stays the same. High works great. So we replaced the fan switch. (Radio was a bitch to remove) and it still does the same thing. I checked all fuses . when I check the plug at the resistor there is power to the center pin it stays on when u switch to low and medium but when u turn high on power goes out( on test meter) is there something I am missing? the blower blows on high even when u remove the plug from the resistor. Is that normal?.
View 4 RepliesDid a 1600 mile trip and noticed that the cruise 2x would just shut off. Most of the time tho it ran fine. Every once in a while when I would stop for gas and turn off the motor the cruise would not come on at all when we headed back out. Sometimes when it did this it would not come back on till I shut off the truck and then restart. Other times it would work after 20 or so miles.
When it did shut off or not come on, I would try turning it on and off, mashing the buttons HARD, What to do? Or should I just take it to the dealer and be done with it?
