I have an '03 F250 and the second position of the blower switch doesn't work. The first, third, and fourth are all fine.
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.
The heater blower in my 1999 F350 continues to run after the switch is turned off. I checked the relay and it is working properly. Looking for a wiring diagram showing the control circuit for the blower?
Do the heater switch controls power to the relay coil or if the switch grounds the coil to pick up the relay?
I'm getting a random 'no start' fault which I think is related to a clutch position switch. The dealer tells me the clutch pivot bushing and master cylinder push rod are worn out, which is causing the switch not to close when the clutch pedal is depressed.

I have a 2008 f250 with 6.4. Was sitting my truck with key on and motor off listening to radio on lunch and my wipers came on by themselves. Switch was in off position and we're in slow speed. If I turn switch they wouldn't change speed til high position. Turned key off and back on and they came on still. Pulled 30 amp fuse in battery junction box to shut them off.
View 3 RepliesHave 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 RepliesI 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 11 RepliesWas checking fuses for why my 3rd brake light and pedal adjustment switch does not work. Was also looking for a fuse to tie into so that a light in the cab floorboard will stay on when the headlights or marker lights are on... After trying several spots to no avail (finally putting it into the bright headlight fuse). I got the light to work.... But now my ABS light stays on!!! Also 3rd brake still not working...
View 1 RepliesI have a 2003 super duty V10 4WD super cab long bed.
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
Having trouble tracking down the problem with my 4wd. Its a 2003 6.0. My esof switch is not working. The 4wd light comes on when I start the truck but nothing after that. I checked fuses and the relays under the hood everything is good.
View 2 RepliesMy son has a 2003 Super Duty with auto locks, but the front wheels won't lock even when turn to locked position. Also when it's in two wheel drive the front drive shaft and axles still spin, are the hubs locked up or is it in the transfer case?
View 10 RepliesRecently 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.
View 8 RepliesHeadlights work well w/ ignition switch off. High/low/passing all ok. When I turn the ignition switch on, there's a strange wheezing sound for a second.
When the ignition switch is on, there are no headlights.
What's the wheezing sound? Why does the power to the switch quit with the key on? The more I work on modern trucks, the more I like my 1968 f-250.
I just got my truck recently, when I purchased it the power mirrors do not work. Already checked the 5A fuse and it is good. Tried putting in a new switch from O'Reilly's and still did not work. Are these switches supposed to light up like the window and lock switch? Thinking it might be a break in the wiring or motors are seized but I've read that is not as common.
View 1 RepliesJust bought a 2003 5.4 6 speed 4x4 F250 .. The cruise control does not work at all. The only fuse I can find in the owners manual is a 2 amp one .. it is in good shape .. Where do I look now to solve the problem??
View 8 RepliesI recently purchased a 2003 F-250. The door locks don't work properly, the passenger side will lock the entire truck all 4 door locks actually lock. The unlock on the passenger side does not work and neither does the entire switch in the driver side. I attempted to switch the actual switches from the driver to passenger side thinking that it could be a switch that is broken.
After doing that still only the passenger side would lock and the rest of lock unlock buttons did nothing. I have checked all the fuses in my truck and actually took the door panels off today thinking I might find an obvious problem. I know the actuators are a common problem but because all the locks lock in the vehicle I was thinking it might be something else.
I have a 2003 F250 Lariat 6.0L Crew Cab. My wipers, radio and power windows don't work. I have painstakingly checked every one of the fuses to see if there was one or more blown. All were OK.
I removed the fuse panel under the dash and have disassembled it to look for obvious clues, burnt wires/heat damage etc. but everything looks fine. Have pushed all of the fuses in to make sure they were seated properly. No joy.
I recently replaced one of the back windows in my truck and had to detach the rear dome light and I remember one of the wires sparking. Where to start diagnosing this problem?
I have a 2003 F550 6L diesel flatbed truck. Last week, the overdrive button would activate by itself. I'm assuming there was a loose wire so I taped the button to keep the overdrive off. Two days later, the overdrive came on while the button was pressed in and then smoke came out of the steering column/lever area. I pulled over and turned off the truck. The smoke stopped after 10 seconds and I restarted the truck. The overdrive light/functionality no longer worked and the instrument cluster also wasn't working.
The next day I was driving, and the truck died at a stoplight. I got it towed home, and opened the steering column and noticed that the overdrive button wire had burned. I removed the harness clip and charged the batteries. It started but the instrument cluster still didn't work. 2 minutes later the truck died. I replaced the alternator but still it won't charge the batteries. The truck dies 2 minutes after getting a battery boost to start the truck. The instrument cluster also doesn't work. What could be causing this issue?
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.
