Blowing out hot air

Thanks for this post I got a new actuator for $56.00 all fixed I love this site

Air Conditioning problem
1999 Ford E-Series Van V8

Hi
I just replaced the evaporator coil, accumulator and orifice tube, because of poor air flow from a dirty clogged evaporator coil. The tempature coming out of the vent on hi still does not get cold enough. (57 - 58 degrees going 55 - 75 mph and 60 - 63 degrees going 40 - 55 mph) My mechanic says all pressure readings are normal and he can't find anything wrong. I checked the heater core and stopped the flow of hot water and it did not raise the temperature at all. Is it me or do you agree I have a problem? What is the normal working pressures at Idol at 90 degree temp? What can I check next to get it colder? Its hot here in Florida.
Thank You

Here are my gauge readings.
Low 46 - High 275 idoling and fan on high
Low 30 - High 230 - 240 idoling fan on low
Low 32 - High 325 - (360 second time I checked), 1500 rpm fan high
Low 23 - High 260 - (270 second time I checked), 1500 rpm fan low

The fan clutch works. The temperature in the vent would not go lower than 70 degrees. Sorry I did not open the door on the test.

What do I test or look for now?

Thank You

My van blows warm air when set on cold, even with ac on. Heater core was replaced, as well as thermostat, and flushed antifreezer. Any ideas? Thanks!

Front A/C vents blow hot air. Rear A/C is ok, cold air.

Hello.

My 92 Ford Econoline conversion van has an issue with the Air Conditioning. The AC blows cold. However, when we go up a hill or I accelerate and put any real load on the engine, the AC stops blowing until I ease up. When I looked under the hood this afternoon, there is a lot of condensation on the canister and hoses.

Any ideas what my problem may be?

5.8 w/ factory rear air, has had new compressor orifice(front), expansion valve (rear) dryer. System was flushed had some metal in orifice but hardly any came out of the system during flush. Both Evaporators looks pretty clean on outside. Charged 65oz as per sticker. Today ambient temp was 91deg and vent temp was 80deg. (About same as before system was serviced, old compressor was leaking though) low pressure was 50 high side was 255. New fan clutch. Removed heater core cover and verified blend door operation. A good friend of mine has a 93 almost identical that will freeze you out what am I missing here.

I have 1992 Ford Conversion Van Mark III. It has a rear AC unit that has stickers that it is made by Atwood. It draws Freon off of the front AC compressor which has recently been serviced and blows cold. The rear blower works but will only blow hot air. At the point where the AC lines go in to the unit one is they are cold ( can't remember if one or both) It also has 2 hoses for the heater that are both hot in and out of the unit. I have only found one Vacuum line going near the unit and looks to control the hot water lines going in to the heater core. There is Vacuum there and when the vacuum is removed part of the switch moves but doesn't seem to effect the temp of the air coming out of the rear. Any Diagrams of the Atwood system or insight on how the system works would be greatly appreciated

Thanks that was what I was leaning toward. It was moving that way when the vacuum was applied didn't cross my mind that it wasn't closing fully. I will check it when I get home.

Eastcoastautotoys Who bought Atwood some years back they had the part in stock and confirmed that the symptoms pointed to that water valve being the problem. I will follow up when the part arrives and install it
Thanks again for your help.

Yep that was the problem. Haven't driven it for an extended period of time yet but let it Idle for 15 or 20 min and the air didn't heat up which is better than it was doing before. Now I just need to figure out the rough Idle in the van after I let it warm up and the van should be good to go. That will be another question that I pose on a different thread.
Thanks Again
