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 6 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 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.

My 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 RepliesHave a 2007 F250 6.0 diesel with the standard issues including misfire at highway speed. Assume the bulletproof kit also cures the stiction problem? in reviewing the threads and looking at the vendors, references are made to fixing the oil cooler issue, egr issue, etc., but no one addresses stiction issue directly.
View 10 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 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 RepliesChecking out my 2007 gasser this weekend an found that my third brake light does not work....no power to the socket. The cargo lights on either side of it in the same assembly work fine so I believe the ground to be intact. My question is does this light have it's own fuse? if not where should I start looking for the solution to my problem?
View 1 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.
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?

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 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.

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.
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?
1999 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 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 RepliesMy battery light on the dash came on so I tested the battery and it's OK. The last time the truck was started it was 10 degrees and ran for about 3 minutes and shut off because I knew the alternator had to come out. Next I pulled the alternator and had it tested and found to be bad. It was rebuilt and put back in along with a new belt. The motor cranks over well but will not fire. I checked the fuel pump shut off switch and it had not popped up so it seemed fine. The fuses look ok. I ran the battery down a bit so I put the charger on it to bring it up to full charge. When I pulled the alternator I touched it's battery wire to metal for a split second. Sounds like I need to do a pressure test on the fuel system or listen to see if the pump is starting. The truck has 130,000 miles on it.
