Ford Super Duty (1999-2016) :: F250 - Surging - Heater Controls Default To Defrost When Driving
My truck at idle sounds like it has aftermarket cams and the exhaust coming out of the tail pipe smells really rich. when driving down the road my heater controls default to defrost. Also when I fill up with gas it takes forever to get it to fill all the way. I am lost on where to begin with the problem [ I did check the tank vent hose and their is no blockage] Possible vacuum issue?

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?

When i turn my heater on, the ac come on instead. It does not matter what position any of the dials are on as soon as I turn the blower on the ac comes on. I do not see anything obviously wrong with the controls. All turn as they should nothing is striped. I have the 3 dial control setup no auto heater controls at all. and nothing is digital.
View 2 RepliesFord Excursion :: Heater Blows Warm Air But Not Hot
I've noticed that my X in the winter does not seem to warm up as it should. I watch the temperature gauge and notice that it barely gets to the first mark in the operating zone of the gauge. The heater blows warm air but not hot. I think its the thermostat that needs replaced because in other vehicles I would see the temp gauge rise and then drop when the thermostat opened. I've flushed the radiator and changed the fluid and not difference. I did find the heater valve on the right side was unhooked from the vacuum line and plugged it back in but no change from that being connected. Anything else I should check?
View 5 RepliesFord - Explorer :: 2006 - Heater Controls / Air Does Not Blow Through Some Of The Vents
To kick off the coldest week (so far) of the winter season, I noticed a problem with the heater controls in my 06 Explorer with manual temp. controls. No matter which fan settings I select (defrost, panel+floor, etc), air does not blow through some of the vents. I can hear the fan working and air flows through the defrost vents and through the floor vents, but the there is no airflow through the vents below radio and round vents on the far left and far right sides of the dashboard.
Perhaps related to this problem, a couple months ago I replaced the blower motor resistor because fan speeds 1 and 2 did not work, only 3 and 4 worked, so whenever I would turn on the heat or A/C, it was on full blast all the time. After replacing the resistor, the issue was resolved and all of the speeds worked well. I guess I just never realized the issue with the vents, or maybe the problem happened because I replaced the resistor?
Since I'm not too knowledgeable with the climate control circuit, I'm not too sure where to begin, perhaps the switch or blower motor?

View 7 RepliesFord - F150 :: 2003 - Run Hot / Blows Cold When Heater Is On?
A friend has a 2003 F150 that after starting up will run hot but blow cold air when the heater is on. The truck will run hot for ~ 5seconds then all of a sudden the temp drops to normal range and the heater begins to blow hot. Simultaneously, the oil pressure light comes on when the truck runs hot, then falls to the normal range when the temp drops. I thought perhaps the thermostat is in backward.

I have a 1997 ford f 150 lariat with the 4.6 v8 and my engine had a piston slap so I replaced the engine with a used one and I put a new water pump on the engine. My problem is the heater does not get hot and it only gets warm when I get on the freeway and the rpms stay steady for a bit. but when i idle it just blows cool air. the heat door works cause I can turn it to cold air when I'm on the freeway and i just replaced the thermostat so I don't believe its that. It weird because the heater worked fine before I changed out the engine so i cant figure it out. the only thing i can think of is the water pump is bad out of the box. Could it be the belt or does spacing on the water pump have something to do with it. nothing is leaking.

My 95 explorer heater only blows out cold air. I have topped off the antifreeze and just replaced the thermostat. The engine operating temperature is very cold, it won't even come up to the first mark. It is very cold here in Utah but I still can't imagine why the engine won't heat up.

I took the dive into a new heater core, as the heater was not getting hot. These are the things I did while on my adventure.
1. Before reinstalling the hoses, I blew thru them to make sure of no clogs...water flew out the other hose..no problem..no clog.
2. inspected mix door not cracked or broken...no problem
3.actuator opens and closes ok, I assume, I can hear the motor run and the door thump closed...no problem
4. water and anti freeze level good....no problem
Start vehicle,let warm up, turn on heat.....No Heat...
5. check hoses at core, one is hot ,the other is not....Problem...

Ford Excursion :: Heater Blows Cold In The Back
The heat up front blows nice and hot but no matter how I adjust the rear ceiling mounted controls it blows cold in the back. Is this a blend door issue or something with the rear controls? Also, on a side note, one of my rear power vent windows just stopped working too. I guess it's either the overhead switch or the motor back there.

I have a 2000 F-150 and my lights to my gauges and heater controls quit working. I checked all the fuses inside and under the hood. All good. I swapped a few relays around and no luck. I tried replacing the headlight switch and that did not work. I checked power to the gauges from the headlight switch and there is no power, I then ran a hot wire to the wire that powers the gauge lamps and they do light up, so it is not a bulb issue. I assume I am not getting power, but do not know where else to look?

1998 F150 step side, 4.6 V-8 automatic, 176,000 miles -
Heater begins to blow heat as the engine warms up - heat gauge moves up to normal level - running at speed, suddenly the heater blows all cold, the heat gauge pegs to total hot - the oil light comes on, the engine begins to miss - stop the truck, shut off the motor, wait 10 seconds, start back up and all is normal and away I go. Heater working just fine. Gauges are just fine. Have checked the hoses when it pegged to hot, and they are just warm just as if everything is normal.
Problem is intermittent.
Have changed radiator reservoir cap, thermostat, made sure fluid level and mixture is correct - what else to check? Computer issue?
Ford A/C :: 1999 F150 - Heater Not Working / Air Blows Cold
I have a '99 F150 4.2 5 speed, my problem is, my heating isn't working. My A/C works fine, my blower motor does too, i changed my heater core about a year ago. I turn my truck on wait for it to warm up and once my gauge reads normal temp, i turn my control to the warm position but the air blows cold with just a very small hint of heat. I looked it up in my Chilton book and they said to check my hoses that go to the firewall/heater core. They say that both hoses should be hot and if one isn't to check it. i did that and the one on the left side(facing the truck) is barely warm. what could be my problem? heater core? my friend from Autozone said something about a vacuum control somewhere in the engine compartment but i don't know where it is, could that be a problem? Or would the flapper door be stuck?

View 14 RepliesFord - Explorer :: Heater / AC Only Blows Out Through Defrost Vents No Matter What Setting It Is On
My wife's '02 Explorer has developed an issue with the heat/AC. As far as I can tell, the heat is hot when it's supposed to be hot, and the AC is cold when it's supposed to be cold. But, the problem is that everything only blows out through the defrost vents, no matter what setting it is on.
I know there are other threads on this type of subject, and I have read a lot of them. I thought I had identified that actuator gizmo as the culprit, but the more I read, it didn't seem like the symptoms for that issue are exactly like mine. I want to try and fix it myself, and I'd love to take the time to read everything on the subject, but warmer weather is here and my wife wants it fixed yesterday!
This problem reminds me of the time the vacuum pump went out on my F-350 and the defrost vents were all that would work. I wish this problem would be as easy to fix as that was.

View 6 RepliesCrown Victoria :: 1999 Ford - Temp Gauge Hardly Moves (up) And Heater Blows Warm Air Only
Ford crown vic, 1999, 125k miles, no engine work has been done, did flush cooling system in spring of 2013 and put in a 50/50 mix of coolant and distilled water (from a jug). No problems for the summer of 2013, have been using heater with no problems until around Tuesday of this week.
Car runs fine, no leaks, coolant checks out good. BUT now.. My temperature gauge hardly moves (up) and the heater blows warm air only. If I am driving the gauge will not move, if the car sits running for awhile it will move up some and the heat will get warmer inside of the car. My guess maybe a stuck thermostat?
