Ford Super Duty (1999-2016) :: 1997 F250 - Cold Engine - Heater Would Blow Either Cold Or Slightly Warm
I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

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 F-150 - 1997-2003 :: No Heat / Both Heater Hoses Are Cold
Ok I have a 97 f150 4.6L. My radiator has been bad for a while. With brown rust color. I replaced my radiator, thermostat, new upper and lower hoses. Everything runs great but I have no heat. I flushed everything including the heater core. Core is not leaking into cab, and both heater hoses are cold. FYI heat worked great until 5 days ago.

I have a 97 E-150 with factory air (vin L) the heat/cool quit working just before summer it quit blowing cold. The old man took it to some mechanic (i hate when he does that) and he fixed it so there was air only saying he had a choice of cold or hot (being summer in the desert he chose cold). Now that it is cold and we are traveling where defrost is needed, I need heat!!! I went to the Ford dealer and picked up a new potentiometer and that did not fix the problem. whenever the unit is on the a/c compressor kicks on........ Is this electrical or vacuum and where might i find the problem?

Here's what I have. 02 X 7.3L 4x4.
Heater will work fine. Then out of nowhere just blow cold. I can turn it off then back on it'll blow hot for 1 minute or 20 minutes. Then out of nowhere blow cold again. It doesn't matter if I'm highway driving or city driving.
I'm kinda thinking it may be the door in the duct that's just closing. I real don't know.
Santa FE SM (2001-06) :: 2003 - Air Conditioning Does Not Blow Cold
I have a 2003 Santa fe 2.0 diesel which I got 2 weeks ago, but the air con does not blow cold, I suspect that the air conditioning needs re-gassing, my question is how often does the air con need re-gassing on the santa fe, I've had cars before and for a number of years and the sir con always have been fine, I just hope it needs a re-service , are there any common faults with the air cons on a santa fe?
View 1 RepliesFord F-150 - 1997-2003 :: 2001 2WD - Heater And AC Not Working
I have a 2001 F150, 2WD, 5.4L. Neither the heat nor the air conditioning works. The blower works fine on all settings, and the air blows out of the correct ducts in accordance with the switch settings. The problem is the heat does not blow hot, and the AC does not blow cold. Everything is just the temperature of outside air.
If I jumper power to the compressor at the relay socket in the fuse box, I can make the compressor run and it provides cold air. The relay does not seem to be the issue because replacing the relay does not work. The heater core is hooked up, just no hot air.
I was thinking maybe the problem is in the temperature level switch in the dash panel. Does that sound like the best possibility? Do you think these problems are connected, or am I looking at two different issues.
Ford F-150 - 1997-2003 :: Heater Blows Hot Then Cold / Moisture Coming Out Tail Pipe But No Coolant In It
I have a 2003 Ford f150 5.4. Heater blows hot, then cold, then hot then cold. When it start blowing cold it pukes out the degas bottle. I have burped it, did the combustion test to make sure not a blown head gasket, the oil clean, there is moisture coming out tail pipe but it has no coolant in it. flushed heater core, pulled water pump off and checked it, its good. Changed thermostat 2 times, put front on ramps to get any air out. I am at a total loss now.

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

View 3 RepliesJeep - Grandcherokee :: 1999 - Heater Broken / Fan Only Blow Cold Air
My 99 grand cherokee's heater is broken - fan blows but only cold air. I've had two mechanics tell me its probably the blend doors and will be quite expensive to repair because it requires removal of dashboard. Looking for after market repair kit which allows for a DIY fix going through the glove box? Is this a good bet to try?

View 11 RepliesPrius (2010-12) :: AC No Longer Blow Cold Air And Rubber Smell When Heater Is On
I took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.

Push A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?
Honda - Accord :: Heater Suddenly Blow Ice Cold Air And Odd Shaking Routine
2005 Honda Accord.
Problem 1: Now that is is finally getting below freezing and I am having to use my heat, and I have noticed that it will all of a sudden blow ice cold air. It does not matter if I am idle / accelerating / decelerating. I must provide a disclaimer... I have not had to use the heat in the car since I purchased it Certified Used from the dealer in South Florida. After moving back to where it actually gets cold I find this issue. I had my trusty mechanic look at it and he flushed the heater core. That is problem 1.
Problem 2: For about 6 months now my car has been doing this odd shaking routine. It happens probably every time I am out driving. When it starts to shake, I can prevent it from dying by revving the engine. It does not matter if I have just started the car, am sitting at idle or if I am driving down the road. No check engine light or malfunction indicator light has come on the entire time. It feels like the car just runs hard, not nice and smooth like it used to. I have brought my car in to the trusty mechanic three times now and he can not find any problems. I did notice this morning that while sitting idle at the stop light, my car had its little epileptic shake and then stopped and the RPM's dropped to 500.
Later when I arrived at my destination, while sitting at idle before getting out of the car, the RPM's were at 2000. I have routinely put in fuel injector cleaner additive when I fill up with gas... maybe once a month. I usually fill up with regular gas, but will occasionally fill up with premium. This whole situation is blowing my mind!
Ford F-150 - 1997-2003 :: 2001 - Heater Core Leaks / AC Just Stinks While Running
My heater core must have sprung a leak this week. Not that I need heat in this weather but just the smell of it while running the A/C just stinks. I know I am going to have to replace it myself but just for S&G, what would a dealer charge to replace it?
View 4 RepliesFord Super Duty (1999-2016) :: 2001 F250 - Heater Blow Warm For The Most Part
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?
