Defrost not working. Looking for the vacuum pump so I can troubleshoot it. Where to find it in the engine bay and trouble shooting it other than listening to whether it's on or not when engaging 4x4?
View 14 RepliesReplaced the vacuum solenoid.. Thought that would fix the ac blowing threw the defrost when I switch to 4x4, but didn't fix the issue, 4x4 works great. There is another little diaphragm that has a vacuum line to it that opens and closes, could this be causing the air to go defrost? I'm going to go to a buddies house and test for leaks this Saturday, just trying to get a jump on it...
View 1 RepliesHave 06 super duty . Heater air blowing only on defrost. 4wheel drive. Is this a vacuum problem or some type of sensor or control problem?
View 2 RepliesMy 2006, King Ranch, 4x4, 6.0's air conditioner only blows from the defrost vent. I have done some research on here, but haven't seen anything that identifies as a common problem. I did however, notice that this problem is stemming from a vacuum issue.
View 10 RepliesNo matter what I do with the settings for my heater in my lariat air only blows out of the dash vents. Defrost and floor vents don't work it still blows hot air out of the dash vents. I'm not sure what the deal is maybe the vacuum system? I did a search and all I could find was people having trouble with air ONLY blowing out of the defroster and my case is just the opposite.
View 8 RepliesThe floor and defrost vents work. It just stays on defrost when you try to use the dash vents. The actuator seems to be working fine. I can watch the arm move through all the motions. and I cant find ANY vacuum leaks. Yes I looked at the hubs and under the hood. May be moving to alaska and kind of need my heater to work properly. . . .
View 5 RepliesIt blows, but only lukewarm..... feels like it's out of or low on freon, but I won't know until tomorrow. Searched the forum but I appear to to be the first with this issue? I just hope it's covered under warranty, whatever it is.
View 14 RepliesI can't seem to get my fog lights to work. i checked am both bulbs are good. I did pull out the headlight switch. I checked fuse 43 an its good. I popped dash out an checked wires to headlight switch an found the wire for the fog lights, yellow wire on my 05.
Its getting power when I pull the headlight switch out to turn on fog lights. Pulled plugs of of fog lights an getting no power to them.
They use to work. i put in some HID headlights an they still worked. then i put some led's in my instrument cluster an sometimes they would work an sometimes not. now they wont come on at all.
I went on a 4oo mile trip the other day and kiddos were in the back playing games and powered up- Next thing I know the AC seems to not be working. It was pretty cool outside so I tested it a little and I could not feel any cool air in the seats and teh vents were not very cold.
Clutch seems to be engaged and not cycling.
I am taking back to them Wednesday.
My truck does mostly pavement duty so no telling how long ago 4WD quit working but I needed it the other day and it's now a no-go. It's the '06 truck in my sig and it has ESOF.
When I flip the switch (4hi or 4low acts the same) my A/C continues to come out of the dash vents, it doesn't change. With KOEO I can hear a whirr-click from under the truck when switching 4wd on and off, I get noise both ways. 4x4 light on the dash seem to work correctly.
Broke out FORScan and got the following info:
===GEM DTC P1832===
Code: P1832 - Transmission Transfer Case 4WD Solenoid circuit failure
Module: Generic Electronic Module
Diagnostic Trouble Code details
Transmission Transfer Case 4WD Solenoid circuit failure
===END GEM DTC P1832===
[Code] ....
Any tips to quickly nail it down between the switch, GEM, wiring or solenoid? Looks like the whole thing is failing. I've climbed under the truck and all the wiring appears undisturbed. No recent work under there. In FORScan, these DTC's were generated in a user initiated test and I didn't pick up the instruction to re-run the test in 4x2 mode until I posted just now.
Under the hood everything seems to be routed correctly and connected. Vacuum pump runs a short while on start up like always has. I can lock hubs manually and they don't seem to be binding hard but they are a little stiff, haven't done that before so I don't know how hard it should be to turn them. I have a MiteVac but haven't tried using it to try and lock the hubs. Not sure any of that matters (yet) with the DTC's listed above.
Do the gauge cluster out of one super Duty will work in another truck, just plug and play? I have a 2015 550 that the fuel gauge has quit, which is causing the truck to go into limp mode because it will not allow a regen on the DPF. This is a business truck and i need it to be rolling. There appears to be a national back order on gauge clusters from Ford. I have another truck in the fleet that I could do without so I was wondering if I could just swap the clusters would it work?

View 11 RepliesMy dads truck is an 04 and we have went through this before. We replaced the whole head light switch and they still didnt work. All the sudden one day they started working again. They have worked recently until now. Same condition as before, the fog lights work, parking lights work and when you pull the lever back for high beams they come on as well but no headlights. Looking for a diagram to track this down.
View 7 RepliesWas driving today and noticed that at idle my heated air went away. Coolant temp at this point was 185f. Once back to driving, the heat returned. The variant in temperature seems to be related directly to engine speed. What is wrong?
View 7 Replies My Edge is reading "PO528: Fan Speed Sensor Circ No Signal". When I'm pulling a large 5th wheel up a 4% hill by the time I hit the top (if I don't slow down)warning beeps are gong off and my ECT is at 240. I can hear the fan come in at 215 and it stays in all the way up in temperature.
All the posts say c/o the fan clutch. While that may fix the fault signal, would it do anything for the temp situation. If the fan is locked in it seems like a lot of money just to clear the fault. Or......is the fan still slipping but sounding like it's working? This my be not related but I did notice that as the temp rises the AC starts not working. By the time I reach the top of the hill it is blowing hot. As we go down the other side and ECT comes down, it starts cooling.
Why my subwoofer won't work? Dealer is stumped. Dealer changed out the speaker and amp. They have been waiting on the Ford Hot line for over a week to get a direction and nothing yet. The speaker does move ever so slightly on highest level.
View 12 RepliesOne thing I noticed with my truck was that the sound was really poor (truck is fitted with "premium sound") - I followed the common thread and replaced all 4 speakers with the Infinity 6829CF's, when doing it, it definitely improved the mid and high range clarity, but in the lower end there was nothing.
I then discovered no movement in the sub... I am a little electrically challenged, and wondered if you have some pointers (i.e. does it have its own fuse/relay to check)
Went to back out of the driveway yesterday and no picture on my nav screen. It switched to the camera screen but it is just black. I unplugged the connection at the rear of the truck before the tailgate and plugged it back in. Everything seemed fine with the connection. I also have a lock pick installed but if I remember correctly the camera still plugs directly into the nav unit.
View 14 RepliesI have tried the dealership 3 times and have not been able to get the rear heater to work properly. When the vehicle is moving I have heat but if I slow or stop the heat goes away. I believe it only happens to the rear heater as front feels fine.
View 4 RepliesAny clue as to why when im sitting at idle or at very very low rate of speed my A/C seems to work like a charm, but if i am traveling down the highway or basically anything above 40mph it seems to die down, like doesn't even keep me that cool..
