Ford Super Duty (1999-2016) :: 2011 F250 - Heater Start Blowing Cool Air After 15 Minutes Or So?
My 2011 F-250 just started having a weird heater problem. My truck heater gets up to temp just fine but after cruising down the highway for about 15 minutes or so it starts blowing out cool air. I can turn the controls to defrost and back again and it blows warm, not hot but warm then cool again. It just started a couple of days ago. Temp gauges show normal temp also.

I recently replaced my heater core on 2001 F250. Would be a simple job if it weren't for the quick connects on the hoses. Any tool to take these apart on the truck where space is limited?

I have an 01 f250 5.4l standard. #19 fuse keeps blowing. I hAve taken the gauge cluster out and do not see any wires melted or burned. It blows the fuse as soon as I turn the key over. I have read things saying the overdrive but that doesn't work with mine.

Sunday I bought a 2001 f250/5.4 to replace my 91 f250. I didnt drive it yesterday, but this morning on my drive to work the heater was very weak, it seemed to blow warm for the most part, but was barely pushing air even on high. I flipped it over to A/C to see if it blew any harder and it did. Does the blower motor need replace? if so why does the AC blow harder than the heater?

I have a 2001 f250 superduty 7.3L diesel and my air conditioner just randomly started blowing HOT south texas air. I tried to recharge it with refrigerant but the gauge said that it was over charged as soon as I plugged it into the low side port. What is wrong???

Cold no start goes nowhere. I have a 2001 7.3 that will not start in the cold if I forget to plug it in....like last night. I have to plug in the block hater and give it a while before it will start. I tested the glow plug relay,it works fine. I can not find a test for the fuel bowl hear, and I'm not one to throw parts until I accidentally fix it. Any test procedure for the fuel bowl heater? Why this POS is so bad in the cold? Glow plugs tested fine at diesel shop in December, and this problem has been around since before that.

My '01 Super Duty 5.4 has an overheating/heater problem that the dealer can't seem to fix. I noticed my heater was blowing cold then a few miles later it overheated pushing coolant out of cap. Next day drove fine to Ford dealer who replaced my heater core, thermostat, reservoir cap and a hose. Drove it for a day till the exact original symptoms occurred again with a gurgling sound in dash. Dealer kept for a week pressurizing system but no leaks found. Replaced my thermostat again and gave it back. I drove it 300 miles over a week before the exact same symptoms occurred. Brought back to dealer who said that air was in the system, added a bunch of coolant and supposedly got all the air out. Same symptoms still. Brought back to dealer that finally changed the water pump they said had a leak. Guess what, same symptoms. Heater will work fine for days then it will blow cold, then hot, then cold and sooner or later truck will overheat then just as fast cool down and heater will work again. Still hearing gurgling. Dealer said I don't have a HCV.

I got my 1999 f250 super duty v10 about a month ago. It had 200,700 some miles on it. It's now at 201,865. My issue is when I turn on my heater I smell coolant. It's kinda strong. No leaks that I can see. Not in the ground or in the cab or from what I can see of the heater core. It only smells when the heat is on, no smell on the cold setting. It sat for months before I bought it from a dealership. What it could be? Ok now it sounds like I have the ticking death sound. The one people have said happens when spark plugs are about to fail. So I guess new plugs are in order.

I was driving from home to work the other day and it was 6 degrees out. My heat was working good and everything was fine and then all of a sudden the passenger side started blowing cool air. Not cold not warm. Driver side was still hot. It is a lariat and has dual temp zones. Everything I read everyone says blender doors but what would make it stop working out of no where when everything was fine. Occasionally when I start my truck and turn the heat on it makes a popping noise under the dash when the blower kicks on. But it has done this since I owned it an never had an issue. It's 25 below today and I would really love to have completely functional heat. It's an 2008 f350.

I bought the wife a truck a few weeks ago and she said the heater wasn't working well and was noisy. So I hoped in it at lunch today and she was right, barely any heat output and its noisy coming from behind the passenger airbag.

Started to attempt to replace the heater core in my 08 SD 6.4. Didn't know the entire plenum has to come out in order to replace it. How to remove the plenum? My buddy is a Ford tech but I just am not getting what he is telling me and there is next to nothing coming up when I try to search.

The A/C on my 05 F250 6.0 recently would not blow out through the vents. So, I replaced the vacuum pump and the reservoir tank. Once I replaced them the A/C still starts through the defrost vents but, after a minute or so starts to blow through the vents. I also noticed that the vacuum pump never stops running. Is this normal or is there something else I need to look for?

Got a 99 V10 blowing a lot of oil out of the exhaust pipe, to the point where I could fog the neighborhood, cylinder number 10 had original spark plug dirt down in the hole know one wanted to clean it out so I did put new plug and coil now smokes a lot, also truck has 173559 miles, did a half diesel half used motor oil flush tonight, wanted to go for 15 minutes only made it to 14 to much smoke, will put fresh oil in tomorrow, what could be the problem, piston ring blow by, intake manifold leak, burning what I think is oil could be coolant, head gasket no bubbles in oil or antifreeze and antifreeze and or oil are not mixing. Is it easier to pull the heads off with pulling the motor which looks fairly easy or leave it in the truck.

I have 2005 F250 6.0 XLT. I was driving the other night and all of a sudden my dash lights went out. I noticed I was being flashed from other drivers and discovered that my parking lights are not working. A preliminary check of fuses I discovered fuse #17 (15a mini) was blown. I installed and new one and upon turning my lights on, the fuse popped again. My headlights and turn signals work properly. It appears I have a wire shorted to ground somewhere on this circuit.
The truck is completely stock with the exception of an aftermarket radio which I installed two years ago.
I checked all the fuses with my test light and they are all correct (both sides of each fuse). I disconnected the gray connector and black connector in the driver side rear of the truck to isolate the issue. New fuse pops as soon as I turn lights on. I completely removed the tail lights, trailer 7 pin connector , completely removed both headlights. I did not disconnect the roof running lights or the mirror lights. I am completely stumped.
Ford Super Duty (1999-2016) :: 2010 F250 Diesel - Heater Blows Cold Air
The heater blows cold air from the driver side only. Very cold. Vey hot on passenger side.I have read that this is likely a blend door issue. Comments? Fluids are full. I hear slight noises from under the dash like "click click" like a door is trying to activate?? Truck out of warranty. If it is the door I heard the driver side is not as tough to install. Again comments? Instructions?

My 2005 F-250 6.0 liter Diesel FX4 Lariat is blowing AC through defrost only all the time. I have manual locking hubs and when I engage 4x4 it works perfectly through the ESOF switch. So I am assuming the vacuum pump and lines to the hubs are in good working order but there is possibly a cracked line or fuse blown? I've only had the truck for 2 days and it just happened after purchase. I'm a little unfamiliar with checking vacuum but have done reading and I believe I can do it. I am going to get a manual hand pump and pump to 20lbs and loss shouldn't exceed 1lb per minute. I just need to know which direction to look. Everyone else had their 4x4 not working and I seem to be the only one posting that has ESOF 4x4 capability when the defrost only issue is on.

Just bought a used 15 F-250 with 57,000 miles, yesterday tried to start it and nothing happened. Checked the starter fuse and it was blown, replaced it and it immediately blew when i tried to start the truck. Pulled the starter and had it tested and it was good, replaced the relay and still blowing fuses. I have got it to start a couple of times but as soon as you kill the engine and try to restart it blows the fuse. What was the fix? Truck had no problems trying to start before this problem started.....
