Ford A/C :: System Not Taking Initial Freon Charge
Sep 11, 2010
Just got done replacing a compressor, dryer, and orifice tube, flushed all hoses and the evaporator and condenser, blew everything out several times with compressed air, hooked up the vacuum pump and let it run for almost an hour and when I went to put in the new freon, it won't pull it into the system. Low side jumped up to 100psi when I opened the valve to the can and the high side is reading right about 100psi also but the freon is not flowing into the system. Without tearing everything back apart, I thought I would check what could be the problem. I jumped the low pressure switch and the compressor is running.

My Avalon 2006 A/C system was diagnosed with Freon leaks. Mechanic can not locate the leak and he feels it will be from the evaporator down the dash board. He is talking about a $1000.00 job plus one week of the car in the shop. My question is:
1) What the probabilities are that the leak is down the dash?
2) It will be a very intense labor or is anyway to make more simple job?
3) Would a dealer do a better job with the diagnose?

I have an issue with extreme high initial idle at start up. I took my 1998 Ranger with a 3.0L to the local dealer to have some work done about a month ago. Long story short, my number six plug wire got burned against the exhaust rail.
Anyway, I guess they re-flashed the computer to the newest *.bin, or flash version. After that when I start the truck the tachometer jumps up to 2200 - 2300 RPM and then it settles down to about 1500 after a moment or two, then it finally adjusts itself to about 1100 for a few more seconds and eventually ends up at 900 - 1000 RPM.
I confronted Ford about this and they said that Ranger's and F-150's do have a tendency to do that at start up. Ordinarily I wouldn't be too concerned, however I believe that the 2200 - 2300 RPM high idle at start up at 0 F, a bit much.

Replaced the condenser and manifold on a 1997 chevy silverado and drew a vacuum on the system, when adding freon to the system the first can pushed the pressure up to 70 PSI on the low side and it has stayed there.

Had a little fender bender. Right after that i noticed the battery red light was on. When I got it home I took the solenoid off the firewall (all the battery wires meet here). When you put 12 volts to the small terminal, the solenoid pulls in and the two big terminals are connected together. That works. When installed on the truck and startup, I have no 12v voltage at the small terminal. Don't have a diagram, but service manual says something about fuse #14 under the dash feeding the "battery cutout".. Checked that fuse and its o.k. .... where does the 12 v signal to the solenoid come from ? I assume somehow it triggers after the alternator starts charging ?

I have a 2000 Expedition that hesitates and sometimes stalls when taking off from a dead stop. The problem is not consistent and therefore hard to diagnose. I have had it to the dealership and two other mechanics and none of them have been able to fix the problem. So far they have replaced the intake gasket, fuel filter, EGR and PCV valves and have changed the PFE sensor and connecting lines. It seems they are just throwing parts at the problem and haven't a clue what is wrong. There are no error codes in the computer.
So far I have spent around $1,500 on this problem and it is not any better from when I started and it might actually be a little worse. I seem to think the problem is in the fuel system and not electrical because all lights and gauges function normally when the problem happens. I can also sometimes produce the hesitation by shifting the transmission into second gear while going around 50 mph then giving it a good bit of throttle after the engine revs. What could be going on.

This is for my 2005 SF with the 2.7L.
My AC system no longer holds a charge and I'm looking to replace the parts myself and have a professional service it after I finish.
I'm looking for recommendations for reliable brand of compressor. Also, other parts I should be looking at replacing to get another 9 years out of it.

Ok, '99 F450 has had a/c problem for couple years and finally getting around to fixing it(co. truck and enough people complained).
When dead cold, compressor will cycle quickly, like low on freon. Low side goes from 40 to 20 and back again as it cycles. Put a set of good gauges on it today and I can't get it to turn on at all. Even jumped both hi and lo switches.
Originally I was thinking it was the clutch, but when cold I was able to jump switches and make it run continuously. I didn't have gauges then and didn't want to burn it up so now I have gauges and it won't come on at all(when warm). Will have to wait a couple days til I can try it again when cold(like in the morning before it gets used).

I got a 2001 f150 leaking freon on the back of the compressor, can't afford to fix this summer. When I add freon should I get the freon with oil in to get oil in the system or just add regular can of freon, it took about 6 weeks before I need to add any.

OK, until I figure out what to do with the other truck I overheated, I've got another ambulance that needs some work, and I got to have a truck running.
This is the same config - 2006 E450 6.0 dually ambulance with 122K. Starts and runs; I drove it all the way to Houston from Minnesota when I bought it and made several shorter trips since with no problems except the AC compressor leaks freon. Then, I found oil in the degas bottle. A tech said it needs an oil cooler and he says there's some leakage at the rear main seal that's "common with this engine."
Can't recall reading a lot of rear main seal issues here. Is that right? Is oil cooler the obvious diagnosis for oil in the coolant?

Of course my freon all leaked out of the AC compressor and it is squealing pretty bad. I did not want the serpentine belt to break due to a seized compressor so I looked for a bypass pulley kit. Naturally they make one for both gas engines, but not for the diesel. So out comes the string and sharpie, and trips to 2 different auto parts place to get the correct length belt after trying several that were too short. It's 103 inches (8 groove) for future reference to bypass the ac compressor and upper extra pulley. 7.3 diesel.....

I had a new engine put into my 2006 F350 SD 5.4 last year and ever since then I can't keep the freon charged in my ac. The mechanic said all he did was lay the compressor out of the way and didn't disconnect anything ac related. I have 2 different shops keep my truck for a couple days and neither could find a leak. Yet a month later, freon is low. I think I have more dye in my system than freon.
I put 2 of those ac leak sealers, the ones you have to ask for behind the counter and can keep my ac working for maybe 45 days, then throw 3 cans in it. No dye is showing up nor will the sniffer find anything. I hate to go to the dealer because I figure they will want to replace everything. Any tips other than try another shop and maybe they can find the leak.

So I've worked on this A/C for 3 years, I don't drive this truck very much or often, partly because the A/C doesn't blow cold. Its a 99 f250 7.3 ... Here's what I've done, first it was low on Freon so I added some and it got cold, take off driving and it gets hot. After some research I check the clutch air gap and pull a washer. This changes nothing, I put a valve on the heater core, so I could manually shut it off just in case.
This year I replace the compressor because the clutch isn't staying engaged when I revved it up in neutral. I went ahead and replaced the drier and Orifice Tube, the orifice tube was clogged up. So I start recharging the system, and I get 2 3/4 cans in and its blowing cold, low 50's high 40's its 75 degrees outside. The gauges read 35 low and 300 high, I'm a little confused cause it was suppose to hold 41oz from what I looked up but ok.
I rev the motor just to check everything out, the low side heads down for a second then starts going up, the high side starts going up and doesn't stop. The high side goes all the way till it hit the high pressure switch 450 wow. I'm thinking its over charged, I let it idle and the compressor kicks on and the low is around 50 and the high is at 350. So I rev it up again 1800 rpms or so, and the low side drops down and so does the high side. Except this time the low side drops down to 15 " I had the low pressure switch unhooked and looped" and the high side around 225.

Seems like my 2001 f350 7.3 has an ac freon leak on pass side near compressor. AC is blowing coolish air but not cold like is should be. There is green like oil around main line leading out of ac compressor. I have attached several pics to illustrate situation.

Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.
Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.

2007 Ranger 4.0.... Initial start of the day it cranks a bit longer than it should. After warm, it starts fine.

I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.

I had my a/c recharged in April and it was blowing hot again by July. I brought it back in today and they told me that it is leaking out of the Schrader valve on the low pressure side. They told me that they would have to replace the entire line which would cost a few hundred just in parts. Why can't they just replace the valve. The tried calling auto stores for a special part, but could not find one. How to seal or repair just the leaking Schrader valve and not the entire line?

2010 Sonata, AC isn't working correctly so we added 1 1/2 cans freon. Got the temps down to 40 and then it was running for about a half hour, we started the car after it sat for 20 mins and it appeared that the ac "vented" some freon out. The pressures were 225 high side and 33-35 low side, the ambient temp is around 87 degrees. The venting appeared to be committed no from the lower drivers side condenser. I may be wrong, but never seen this before. Anyway, after it "vented" his ac basically stopped working but the ac gauges still read 210 high side and around 25 low side......

When I start my truck up initially and it's somewhat cold, like even if it hasn't run for just a few hours, it seems to gargle when I get on it. I'm not slamming it while it's cold but even just trying to accelerate. Code is egr flow insufficient, the truck isn't egr deleted, I've had it for 150,000 it's got 211 now. I just clean out the egr every 15-20k and it's been great until now. Once it warms up it sounds and runs perfect.
