I have a f250 with 6.8l engine. I can get air thru the defrost and to the floor, but no air thru the dash vents on me. I have traced all vacuum lines and they seem fine.
View 1 RepliesMy heater vents have been acting up. I have read that there may be a vacuum leak that causes the blend doors to default to defrost...
Where the vacuum line fails? I have ESOF 4x4 and that is still working. I think there may be a correlation between engine vacuum and my vents: at cruising or idle the vents work ok (not perfect) and under acceleration (less vacuum) the dash vents stop blowing.
I thought that the blend doors had their own vacuum pump, so I do not know why things change at different amount of throttle?
I have a 2000 F250 7.3 manual tranny that was put away for winter storage and now will not start. Need it to get my weekend work done now that the snow is finally gone. Symptoms:
- not cranking
- no dash lights (no oil light, battery light, etc.)
- radio works
- head lights work
- key buzzer works
- can hear clicking when turn key (assume solenoid OK)
Put in two new batteries, fully charger and terminals are clean. Where should I start looking?
We got a ton of snow dumped on us today and for some reason my 4WD has decided not to work this year. I have a 2000 F250 4WD Triton V10. The hubs click into the lock position and the dial on the dash lights up 4x4 but I am definitively not engaging into 4WD. I'm pissed because this is specifically the reason i bought a 4WD and it's failing me. I can't find a fuse panel diagram to save my life however all the fuses in the interior of truck look to be fine.
View 3 RepliesI seem to be having a run of bad luck with my dash vents. 3 of the 4 vents in the dash have broken and I would like to replace them.
Are these vents made aftermarket? If so who? The dealer wants fifty some odd dollars each.
2011 F350 6.2L Gas engine. Last fall when I first started using my heat I noticed that the air would only blow through the dash vents. It will not switch over to defrost or floor. I have an XLT I am pretty sure the controls are the basic controls. there are push buttons to change from floor/vent and defrost. I do recall the summer before I had I noticed the problem I would hear a clicking sound in behind the dash. I figured something fell down the defrost vent. I see people who have had this problem on older trucks talking about an actuator. I've looked on ford parts site and I cannot find an actuator listed for the damper door. I was hoping to see what it looks like so I could try and find it in my truck.
I do have the dash pulled apart and I can reach up and manually move a lever that is connected to a cable. and I can change the air outlet to the floor, but I cannot get it to change to defrost. While I have the dash apart I also tried pressing the buttons on the heat control to see if the lever which I am moving by hand is moving at all and it is no. I was thinking if something was stuck in the system I would probably be able to feel the cable at least try to move, but it does not. The white cable which is connected to the lever which I am moving goes into the bottom of the duct work, where it goes from there, but I am assuming some kind of actuator?
This is right in front of the 4x4 shifter
Obviously behind the glove box
With the radio removed
I'm guessing this is 1 of the motors?
I stuck my camera up there to see what was there. This is as far forward as I could go on the drive rside and in front of the 4x4 shifter. You can see the end of the cable I'm assuming that is the door.....
Air is only blowing through the defrost vents. No matter what I do - try to turn vents, A/C, heat, fresh air, recirculating, etc. Assume it's a switch or fuse issue somewhere. How to fix it?
View 11 RepliesLast week I flipped the fan switch on and noticed that only hot air was coming from the vents, even with the control set to AC. The vent control switch seems to work fine directing the air but only hot air. The temperature control does not work. The exception is when I put it on max AC I get cold air. I can't be the only one.
View 4 RepliesSo I got in my truck yesterday and i started it like normal and turned air on. The air will not blow out of the vents but only the defrost vents. I have checked all vacuum lines and good, my 4x4 engages and no issue with it locking in. I am Puzzled on what it could be?
View 3 RepliesI have a 2005 Ford F-250 Diesel 6.0 my ac works fine but after working a while the air quits coming out of the vents. It happens every time I go on a long trip with the ac or heater. Is like if a duct damper closes because I can hear the motor blower going. The entire ac system is new but it was doing this with the old system....
View 5 Replies2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
View 1 RepliesI have a 2006 F-250 Super Cab with climate control. The last three years when the temp exceeds about 85 degrees outside it acts up. It will switch from the AC vents to defrost and blow normal air through, not ac cold. Then it will switch back, when doing so I can hear the internal deflector shudder. It will do this every few minutes. It is extremely annoying. All other times of the year it works fine. My local dealer had the truck last year, but could not find anything wrong. I have used the search and also Googled and while I find similar problems nothing exactly the same.
View 12 RepliesMy 1999 F 250 5.4 liter. I know I have a vacuum leak because whenever I accelerate the air conditioning coming from the vents switches to the defroster. So my question is how do I go about finding the leak? My hubs in the front are manual so I know I don't have lines going up there. I do have some mechanical capabilities I've changed water pumps alternators brakes etc. But never anything with vacuum lines or a/c.
View 14 RepliesMy a/c vents smells musty/moldy when A/C is turned on, searched the FTE site and everyone says to check the A/C drain tube to make sure it is not clogged, I have searched all over top and bottom with a flashlight for the drain tube and swear there isn't one. I think it should be on the bottom of the condenser box but just do not see it. Where it is located? The vent smell is Awful!
2000 F350 Super Cab 7.3 Diesel
I'm from SC where we are currently getting our rainfall for the next 3 years, so it's an occasion to find leaks. My 2001 F250 has developed one right in the middle of the passenger side dash, I saw it running down a white vacuum tube and dripping off to the floor mat. Is there a place in the cowl that will hold water and leak?
View 3 RepliesJust bought this pickup is a 2011 F250 xl with the 6.2l. The service 4x4 flashes on the dash. The 4x4 shift motor fuse blows instantly when replaced even with the vehicle off. I then went and disconnected the plug ins from the shift motor and tried a new fuse and it blew again. Not sure where to go from here.
View 2 RepliesMy 99 250 XL only has heat, and the blowthru vent air which in Florida, might as well be heat also. LOL.
Since the vents and everything is there, what all and how hard would It be? I have an extra dash control that I can put since mine doesn't have the ac option on it
2015 F250 diesel. I am hooking up an air pressure gauge inside the cab to report the pressure on my rear aftermarket air bags. The pressure reading will come from a tap on the actual pressure line, but I need 12vdc to operate the backlight on the gauge. I have found a bundle of loose wires under the steering column, 4 of which are firewall pass-through wires for the upfitter switches. Do one of the remaining wires in the bundle is an accessory power wire? I need a plain key-on accessory wire connection, not a dash-light connection.
I am using one of the upfitter switches to switch my on-board air compressor and a second switch to inflate/deflate the air bags. Want to save the other 2 switches for future use.
2001 Ford F-250 7.3 Lariat, Crew cab, 8 ft bed. Have had the truck since about 2007 and 4x4 has never worked. It has the typical ford "self rotting" vacuum lines (which have all been replaced along with the hubs themselves). Took it to a mechanic a few years back and he n-word rigged it (for a lack of a better word) and bypassed a lot of vacuum stuff and it still didn't work. The weird part is this-- the 4x4 light is permanently on on the dash, even if the switch is in the 2wd position. Flip the switch and nothing happens. No sounds, nothing. No mechanic can fix it and I have yet to find a forum with someone having the same problem. (Worth manual transfer case swapping it?)
View 10 RepliesThe light on dash for 4X4 stays on no mater where the switch is placed I have it in 2 wd and it stays on. Where I need to start looking.
View 4 RepliesI am getting this check gas cap warning on the dash. I checked the cap, looks ok... Should I disconnect the battery for a minutes.. and see if it comes back?
