I done the resistor fix and it work for about 5 miles and then air started getting warmer and got back home and seen my a/c line was froze up cut it off took out the resistor restarted the truck and back to mediocre a/c.

 

has anyone tried a heater hose block off valve?


really odd that some are mediocre and others are plenty cold (mine being the latter)

 

I think it depends on what yr you've got. I had an '01 that had a killer A/C system. The '10 I had was just eh, working well on normal days but often struggling to keep up on the hottest of days. The '13 I have now is horrible. It can't maintain 70 degrees inside on a 90 deg sunny day. Here in central NC we're already at that point.

 

So this is extremely disappointing isn't it? I loved my '04 V10 F250 with Ice cold AC until some dude slammed into it.... It kept my family and I safe and I have special place is my heart for it always. I called her Ruby.

Welcome to the family "Blue"... 2016 6.2L V8... shiny with that oh so sweet hood dip.

My A/C sucks. A thermometer at the vent shows it cycling back from 46.3 Deg to 53.7 Deg in and endless loop. On a not too hot day, in the Shade with one vent open and Max AC on.

This is normal then?
I was going to take it back to the dealer....

Same test on a 2005 Tahoe its a rock solid temp 46.7 and slowly dropping, no fluctuations.

Here's a video of it...

 

Yep, I think what you're seeing is normal now-a-days. I recently drove from NC to Hartford, CT to Boston then back home to NC in 4 days. Had the A/C on for most of the trip and was uncomfortably warm for most of the trip. Ford really screwed the pooch with this setup. In the hot sun of the interstates when outside air was 88+ I couldn't get the interior less than 75 and most of the time it was several degrees warmer than that.

 

Mine is running 46.x degrees today on max ac.

How is that not cold enough? I've had to turn mine down even when it is in the 90s and clear sun.

I'm not sure what the complaint is.

 

Hi Mike... it seems to be the cycling up to 53.7 thats the issue.... when the trucks full of people, its a crew cab etc... it just doesn't get the job done like previous models did.

Its totally noticeable if you drive for long distances for a long time during the hottest times of the day. The interior of the truck just never gets as cold as it should in my opinion.

I wish I had my old truck to do a 1:1 comparison of cab temp inside after a set time in the same environment. The net take away is that if you keep blowing out 46 degrees, its going to do a better job than cycling back and forth from 46 to 54.

Thats my thoughts.

 

I suppose the cab configuration makes a difference. Mine is a scab rather than a screw.

I'm sitting here right now waiting on a contractor. The ac is vent temp is between 51-52 with the air on max and blower on high. To me thats plenty good. And on the average, its the same as cycling between 46-54 as above mine just doesn't cycle.

Air temp is 87 and I'm sitting in the sun with no complaints.

Now if I rev the engine and hold 1500-2000 rpm the vent temp goes down to 48-49 and it does feel noticeably cooler, but I'm not uncomfortable with the ac blowing at 51ish.

Just my observations from sitting in it all day for 6 years.
Still better than being outside jackhammering concrete.

 

Mike- the complaint is the newer models. My '01 was great, much as you describe yours. My '10 was ehhh. My '13 does a horrible job, it can't keep the cab less than 75 deg on a 90 deg day.

 

What I have found is that recirculate mode works great to keep the cabin cool. But fresh air mode s u c k s. It won't even keep up on a 85 degree day, much less a 100 degree day.

During winter, same is true. The defrost setting won't even clear the windshield. But if I use defrost/feet mode which allows me to use the recirculate button, then I get lots of air and heat flowing into the cabin.

Unfortunately, the truck won't let you keep it on recirculate because it's programmed to switch after a certain threshold is met.

 

Yeah, I noticed the same thing: recirc works much better with a/c but as you say its time is limited. Once it switches to outside air intake the a/c system sux big time.

I diligently use the recirc mode in defrost too by not using the defrost button at all and selecting a/c, recirc and wind shield. I thought maybe it was me being picky.

 

I get that people are complaining about the newer trucks, but what I'm saying is that my 2010 is blowing out roughly the same temperature out of the vents and the cabin gets plenty cold.

with the vents blowing at a pretty steady 51 degrees, and the outside temp at 87, the cabin temp was comfortable. the temp with the thermometer hanging off the front end of the center console (out of the breeze) was 74°, which doesn't sound good, but with thermometer behind the passenger's seat it was 69°, and in the passenger's seat (with the vents directed up and out) the temp was 68°.. totally comfortable.

this was with the AC on recirculate.

I'm just not seeing how other systems aren't keeping up when, on the average, the vent temps are about the same. I get that the new once cycle and mine does not, but on the average they are both about 51° at the vent. granted, mine does blow several degrees colder when not idling.

it does "time out" on recirculate any time you have it on the windshield. that part does stink. otherwise I would probably never use the vents and I would just have it on the windshield as I don't like the cold air blowing directly on me (generally speaking).

for sure it does not blow as cold with the vents on fresh air. but for me, that's fine. because when it gets too cold in the cab with it on recirculate, I switch it to fresh and it doesn't blow so cold ... yes, mine will get too cold for me on recirculate.

im just surprised that others are finding that the AC is not cold enough, when - as best as I can tell - mine is performing about the same as what has been described by others.

 

I've no issues with my '13s ac, although I wish it had the vents in center console blowing to backseat but my kids never complain of being hot back there.

 

So I guess 50 is about the best these trucks can do because of the temperature switch? I looked at the suction line back to the compressor and it doesn't look like there is a cycling switch so bypassing the temp switch is a no-no as others seems to have already figured out. You'll just ice it out and risk flooding liquid back to the compressor.

My data point: With fan on full speed, AC on recirculate, mine will put out 50F while driving. Once I stop at a light it goes up to 60F until I take off again. Tested that today in the 108F ambient temps.

I'm thinking mine might be a bit low on refrigerant as it seems to take forever to cool down at first. Over a minute to hit 60F. Usually thats a sign you are low.

For reference my wife's 2007 Honda Odyssey puts out just a bit over 40F at all times. Feel much nicer. Also cools down much faster.

Sad as my previous (2) Ford truck's AC were far superior! Both would pull down into the 30s when it was 105F outside...
