Ford Super Duty (1999-2016) :: 2002 - AC Stopped Blowing Cold At All
Aug 9, 2017
Background : 2002 Excursion 7.3L, 320k miles ...
AC was working OK, but not great. Then AC stopped blowing cold at all. Checked pulley, gap was huge, but pulley bearing was completely destroyed. Like, 1/2" wobble, half the ball bearings in there. Amazed it hadn't seized. Replaced pulley, set air gap to bottom of the spec.
Air seems to blow kinda cold briefly, then fades to no cooling after a couple minutes. Same at idle or moving. Front and rear both not cold. Lines in engine bay are cool, but not real cold
Compressor body feels hot, like...right at that threshold of too hot to touch. Don't have pressure gauges, but will buy/borrow some and take some readings.
What would symptoms of a clogged orifice tube be? What would symptoms of a clogged condenser be? If low on r134, I could refill, but any tips on chasing down leaks?

2002 F350 with V10. A/C stopped blowing cold. I can hear the clutch clicking on and off, so probably needs refrigerant? Other thing is that with A/C off, the temp control turned to cold, and fan on, it blows hot air. On my other vehicles with A/C off and temp turned to cold, I get outside air at ambient temp.
I removed the cover off the evap core under the dash and observed the blend door opening and closing as the temp selector is moved. The duct door moves correctly, so am I'm missing something? Is the Ford system such that ambient air is always heated? This happens even in cold temp conditions.

I think the truck needs a recharge, it's not blowing any cold air. The question is - which port do I use? There's one on the top of the accumulator and another in the line just off the passenger side of the radiator, near the coolant tank.
My only recharge experience was after I replaced a leaking accumulator in my 2007 Crown Vic police interceptor, and this obviously doesn't look quite the same.

Here's what's happening:
I can have it on hot and be driving along, then it will start blowing cold air. I can move the temperature switch to cold then back to hot, and it'll start blowing hot air again.
Need to know if that would be temp or the motor? I don't want to just change parts randomly.

I have a 2000 f-350 that overheated 2 months ago I replaced the radiator...it seemed fine for a month then started blowing cold air then would start to overheat and back and forth so I replaced the thermosat.......but when i checked the old one with a cooking theromometer it was fine. not long after that the heater core started leaking so i replaced that..and now its back and forth overheating and blowing cold air....then fine for 1/2 hour..then back and forth again.. Truck has 250,000 miles on it

This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

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 have a 02 F250 with 137 thousand miles. When it had 130 thousand on it I had the plugs changed unknowing that this year 5.4 was known for blowing the plugs.

I have a 2002 f250 powerstroke 7.3, while driving it smokes pure white smoke and feels like its loading up and will start shaking if I floor it, it will rev slowly popping like its loaded up then cleans out runs good for a 1/4 mile than same thing. My temp gauge stopped working and it just seemed to get worse. Stuck it on a scanner and it didn't have any codes but was saying the engine temp was -211f. I got a new sending unit didin't fix any of the problems.

Ok first problem : Starter Motor fuse kept blowing and I spent weeks trying to figure it out. No luck. so wired up a push button just to get the truck started, its a work truck so it was needed asap.
2nd problem : he truck stopped starting completely. Wont start in Park or neutral and after a NEW STARTER (because I thought the solenoid on the starter was bad I replaced it) Everything work correctly for one start with the key. After the second time trying to start it blew the starter fuse again. So I tried the straight wiring to starter. still nothing. I was wondering if there are any shims or anything at the transmission housing to correctly position the starter. I am thinking that maybe the gear is stuck or gets stuck sometimes. when I straight wire the starter it does nothing but the wire gets hot so I know its pulling.

Windshield wipers, and washer were suddenly not working the other day, so I discovered a blown fuse. Put a new one in, and it immediately blew again. So there is definitely something grounding out, and I am suspecting the wiper motor itself because so far I have not been able to find any wires shorting out, but before I go to the trouble of pulling the motor out and testing it, or replacing it.
Truck is a 2002 F350CC 7.3 TD. Wipers were working fine the other day before I pressure washed it, which is why I really suspect the wiper motor itself.

I have a 2002 f250 superduty 5.4 4x4 around 317xxx original motor and trans. When it's cold out it won't start at all I have to use starting fluid but once started it will start right back up. Did the plugs fuel filter cleaned the intake and sensors still have a problem plenty of fuel pressure plenty of cranking amps brand new battery and Alternator. It just cranks and cranks when it's warm out fires right up. Runs smooth no lack of power or misfire no codes are being thrown also.

So one day my 4 wheel drive just stopped working, when I put in 4hi nothing same with low, the light on the dash doesn't even pop up and it doesn't engage. I've done about everything I could think of doing besides replacing the motor for it and the wiring, I hate getting stuck...

Our 7.3 won't fire. After a few weeks of thinking we had glow plug issues on firing we feel we may have another issue instead.
In cold morning of past say -1 to -7 we have had a lot of trouble firing the old girl, we would preheat 3 or 4 times and it would wind over and over. Stop repreheat and try again and it would turn over quicker. Preheat again and it would fire.
We have a diesel leak as well and was thinking that the pressure maybe low because of it. It is now with the mechanic and he can't find the diesel leak but it pools on top of the engine and drains down the back of the motor over the belt housing.
He cleaned it all up and checked the ICP sensor and it was full of oil, he cleaned it and refuted it and it fired. He then ran it for around half an hour to see if he could spot the fuel leak, he turned it off and now it will not fire at all just turn over.

I have been having hard shifting from 1st-2nd when cold. Rpms up to 2000 and let off then goes into 2nd. After that, she shifts fine and shifts well until next morning when she sits overnight. Build tag is August 09, 2001, so no old mechanical diode? Took a sample of fluid and it is dark red (pic attached) and smells like hydraulic fluid...I don't think it smells burned. Does it sound like the calve body 1-2 shift or solenoid pack or needing rebuild?

2002 7.3 running rough.
This is my symptoms : On cold start ups engine runs rough. Idling it knocks worse than normal on the road she runs really rough. If I get on here she smooths out ( but still runs rough a bit) but normal driving at between 1200 -2000 rpm she runs so rough it shakes the whole truck. It will do this until she gets up to operating temp & then it goes away. The more she warms up the better she runs.
Once up to temp she will run perfectly. The colder it is outside the worse it is & the longer it takes for it to go away. I have replaced the valve cover gaskers and new harnesses, new glow plugs. Still same problems. I have AE and one time it gave me a #2 cylinder code. have not been able to repete this code. What to check next.

Having a problem with my truck and I'm stuck. About 9 months ago my 4wd stopped working. Turn the switch and no light or noise. I took a look at fuses and everything was good there. I let it go but now I need 4wd. Today I checked every fuse and all of them were good. I moved to the relays checked them and they were good but for the heck of it replaced them. Checked for power at the pins. The one that needed power had power. Next I went to the switch had 12 volts there. Pulled switch and test with a multimeter and ohms were good. Went. Down to the motor and tested for power there not power to the motor. Is there anything else I'm missing Esof not working. 2002 f350 7.3 auto....

I am the proud owner of a 2002 F250 Super Duty 4x4, which has 158K miles on it. I live in South Florida and use the truck as my daily driver and also from trips up into the Blue Ridge Mountains.
Recently, I noticed that when I have the A/C on it blows nice and cold for about 15 minutes, but then the air gets really warm. I had the system checked and the Freon levels are right where they should be. A bit of experimenting reveals that if I turn off the A/C for about 10 or 15 minutes after it starts to blow warm air, the systems blows cool air as it is supposed to.
Therefore, I suspect that something is freezing under the hood and preventing the system from operating properly. Since A/C is pretty well essential for us in south Florida, this is a problem, when I have the family or customers in the truck.
