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.
2008 F-250 Lariat with EATC climate controls... My truck suffers from the knocking/buzzing/clicking that is apparently associated with faulty blend door actuators. I have been putting off getting them replaced because of the hefty price tag associated with tearing apart the dash and whatnot that is required to get to the lower actuator that sits right on the transmission tunnel. Anyhow, today was the first day I really needed A/C and it just wasn't cold. Cool yes, but not cold. Is there a way to determine if this is a function of the blend door(s) not doing their thing versus the system A/C needing a repair/recharge? I don't have access to any A/C equipment myself, how to determine if it's a blend door issue?

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?
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
View 12 Replies2002 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.
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?

I would like to know where to start looking to solve this problom.
View 12 RepliesMy '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.
View 6 RepliesI 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.
View 4 Replies2001 F250 5.4. The heater will blow warm air at idle and on the second highest setting, once you start moving or turn the fan up to full blast it instantly cools off. The coolant level is fine. The engine runs at a normal temp.The blend door does work. I just replaced the thermostat, and both hoses for the heater core are hot.

View 5 RepliesI have a 01 f350 7.3 turbo dsl. will not start cold. engine turns over fine. plug into block heater over nite , will start! outside temp does not make difference. I have replaced glow plugs, glow plug relay, wiring harness under valve covers. Where to go from here?
View 14 RepliesI changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?

My 2001 6.8 L V10 runs great all day & night without issue, but first thing in the morning when below freezing it has a hiccup. It'll fire right up and stutter and stall within less than 2 seconds. Usually twice. Third time it fires and keep running. Is there a fuel check valve somewhere on this thing? Not sure what that would have to do with the temps. Wondering if it's/there's an easy fix or not?
View 5 RepliesCold 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.
View 14 Repliesthis doesn't make any since to , what's going is, sometimes the AC starts blowing warm air, I found out if I goose it I can hear what sounds like the damper door slamming shut, then AC starts blowing cold again. I changed out electric vacuum pump, but it still does it, starting to get worse & its hot.
Truck is a 2002 f250 powerstroke, the way I understand it, is only thing vacuum pump is supposed to control is AC & 4 wheel locks, my truck is only 2wd. I don't understand why when when I goose it ,it goes to working, what can I do to fix this.
I just found out the " heat and cool "adjustment is electrical, not vacuum, it goes to something under dash, but what it is, heat strip, reastat(sp)??? where and what damper am I hearing. It is not like heater is on ,not that hot, feels like ambient temp, I am at a loss...
I have followed the vacuum lines but don't see any holes or cracked lines. I dont have the ESOF hubs so that is ruled out. Also checked the connector on the vacuum pump to make sure it still had power. Everybody says that when I turn the key to acc I should hear the vacuum pump running. I don't or do I feel it moving. Am I on the right track? I don't want to replace if not bad. Do all vacuum pumps run on keyed power? I honestly don't remember hearing it run before but that doesn't mean anything with my memory.
View 8 RepliesMy problem had been intermittent for last few days. I have a Ford Crew Cab - 7.3 Powerstroke Diesel. The ford store told me it would cost hundreds of dollars to chase this short- to wait til it finally burns out then - bring truck to them.?
My fuse # 45 a 10 AMP fuse . Keeps blowing out. This fuse controls the gauges on dashboard and fuel peddle. I can start engine and if gauges come up like they should- I can place into driver - and give engine fuel from peddle- gauges down dead and no fuel go to motor. It just idles and still runs and will still move forward or backward. But only at idle speed.
I could replace blown fuse - #45 - 10 amp and it would a the first few times would go and work normally.
Now everytime I replace fuse it blows fuse - sometimes after putting 10 or more fuses in- one might work until I stop or put into park. Then fuse blows again??
Last night and today it took no less than 20 - 10amp fuses to get close to home and end up straight wiring with a small piece of electrical wire - severing as a jumper- it ran great - til I stop at mail box and got mail - saw slight smoke and pulled wire quickly out and idled down driveway to house..
Started my truck the other day no problems,minute into the start truck shuts right off like someone turned key. Checked fuses , #30 fuse under the column was blown, replaced it and tried to start truck. No luck fuse keeps popping. After changing again i was able to get truck started for a second and POP goes the fuse?
