Ford Excursion :: Heater Blows Warm Air But Not Hot
Feb 9, 2012
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?

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.

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?

So the other morning I drive the 140 miles out of town to work for the week. when I pull up to the job site the cooling fans were revving really really high! never heard this before. then it went back to normal after I opened the gate and parked my truck and shut it off. I'm driving maybe 5 miles tops to the job and back to the motel every day. however that is far enough that my heater should be warming up and it's not even coming close to warm. it blows cold air. and to compound that I'm not sure the cooling fans are even working. they don't appear to be. Is there a connection here?

I have a 2007 Dodge Charger. The heat blows out warm air. I have replaced the water pump and thermostat. When accelerating the vehicle, the heat turns to hot. Is this normal, perhaps a speical feature? I have 66,000 miles.

It seems the local dealership has finally figured out why the rear ac blows warm while the front blows cold. It only took 5 trips.
The part # comes out to F75Z19A522AA or F75Z-19A522-AA. Its listed on Tousley and other online parts outlet but so far all that I have called said it is no obsolete and they are no longer available from Ford.
Rear inlet door actuator - obsolete part? Where I can find this part (I'll even consider used)?

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.

The front a/c blows cold air but the 2nd row and back blows warm. Yes the temp dial is on cold on both dials. Is there a separate a/c clutch that I dont know about to ck the air gap? Is there a separate port to put freon in besides the front. I need to get this fixed because with my bulldogs in the back the heat will kill them.

Tested/checked the blend door, actuator, Low pressure cycling switch, compressor clutch and they all work. The accumulator does not condense, or at least that I've noticed. The gauge on a can of R134a reads 55 at 85 degrees outside. Anything else I can check to diagnose a problem?

I need to diagnose a heat problem. I have a 2001 F150 XL. 4.2L Manual controls. The a/c blows nice and cold, but when you put the heat on its not really hot, blows warm air. I changed the blend door actuator,it got a little warmer. Now that winter is around the corner need to figure it out and fix it. The thermostat, water pump, and coolant flushed before I bought it. Could it be the blend door itself, or is there another actuator I'm missing.

Here's the situation....It blows cold for about 5 mins, then the air starts to warm and stays warm. I just bought the truck 06 350 crew cab and they supposedly charged the system. I'm wondering if it has a leak but it should start out blowing warm air? I just wanted some thoughts before I start throwing money at it.

I have a 96' Ranger 4.0 5 speed. While driving, if I put the truck under a load such as going uphill or towing, the air conditioner fades out and blows warm air. Once I start downhill the air will come back on. It is much worse when towing.

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.

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...

My 1968 F250 blows hot air with all controls set to off. The truck is fairly new to me and I'm a complete newb with a wrench....or screwdriver.....I think this should be a fairly easy fix? Aside from that it does work well.....it just doesn't shut all the way off.

My AC has been acting up. It blows real cold most of the time, but every now and then the clutch kicks out (even at highway speeds), and it blows warm. If I accelerate, the clutch engages, and it blows cold again. If I decelerate, it stays disengaged. At idle, it will do the same, sometimes cold, sometimes no clutch. I added a can of 134 last week, didn't make a difference. I hooked up the manifold gauges today, and the low side was 45psi, the high side was 160psi. I let a little freon out of the system until the low side read 35psi, but the high side went down to 150psi. If I'm correct, the low side should be between 30 - 40, the high side 225 - 250? Why I'm seeing 35 and 150???

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?

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?
