2013 fusion A/C issues

[Atomlin06]

Car has 112k miles. The temperature here is about 87 degrees today and I noticed my AC is not blowing cold. The AC clutch relay is good. The light comes on when I hit the AC button. It will blow heat just fine and "vent" temp air but no cold air. We hooked up AC gauges and a can of freon and it is completely full of freon. We found no leaks in any lines. When I bought the car in February it was a lot cooler outside and it seemed to work ok when I tested the AC. However, I can't honestly tell if it was just blowing cold air or actual AC air. With the car running and hitting the AC button to turn it on. I can feel the engine bump as if it's telling the compressor to kick on. From the research I've done there is some kind of labor expensive inexpensive sensor I could try changing. Any help would be greatly appreciated.

Thanks in advance.

What are the high and low side pressures with the gauges on and the AC running? At what temp?

 

Evaporator temp sensor may be worth checking with a scan tool

I have the same issue. Mine is a 2012 Fusion SE. Manual control A/C. Have switch to hot, to cold-no effect. A/C compressor comes on when switched on. I have changed the Evap Temp Sensor already, with no change. Still blows hot air!! This is my wife car and I am driving it till its fixed. Any and all help, advise is appreciated.

I had this issue with my wife's 2007, not sure if the solution is the same. There is a temp sensor under the dash when it fails it fails and reads cold, when it is too cold the AC will not run, everything else will check out fine.

 

Watch this video here what a pain in the ass it is!!!!

 

 

Here is the quick fix, newark electronics or arrow should have the resistor

Please let me know if this works I spent 700.00 on my wife's car because I did not search enough.

 

there are also 2 ambient air sensors could not find much on them but says easy to replace

There have been numerous discussions here on the topic of replacing the evap. temp sensor. WRT the "quick fix," see this thread.

YOU can bet your ASS Ford has a fricken tool that will let them reach down there thru the defroster duct and remove that sensor..I guarantee they do. So it takes them 15 minutes to do the job and they screw the customer for 5 hours work they did not perform. Every dealer that has that tool should be sent to prison for 10 years on each job they did for fraud!

OK!!!!!!!!!! Removed sensor and plug from junk car, Removed blue connector from behind glove box, removed pins 3 & 4, connected junk yard plug to these two wires, yellow/purple stripe & purple one. Plugged in new from NAPA Thmo/sensor $23.81. Reconnected blue plug to harness, fired up the car, pushed the A/C button and "wallah" the A/C compressor roared to life and every thing works, all fans come on, all speeds work on A/C, all settings work on the vent dial.

You could do this without the junk yard connector...while your at NAPA getting the new sensor, pick up a couple of female pin connectors & a couple of male pins that fit the pins in the sensor, add a length of wire to them and wrap the other end of the wire to the connector pins you removed from the harness, or just plug the two wires into the sensor. tape securely and place in a tywrap to something under the dash to hold in place. Yea a bunch of FORD tech's are going to tell you it will freeze up, so what, if it does just turn the damn thing off for a few minutes and let it defrost, just like you had to do back in the good ol days with all automotive A/C systems once in a while, big deal.

Oh and I forgot, it took about 15 minutes, of course this is the second time I had to do it, because the Junk Yard sensor I got was also bad.

So basically what happened was that my compressor was actually bad. I replaced the compressor. It ended up being a $1000 job because ford simply does sell the compressor individually. With that being said. Everything was replaced and working great until my car sat in the heat all day while I was working. Come to find out. The pressure gauges I used to fill it were off. Apparently these fusions are very very sensitive with freon. When I bought a new AC gauge system I ended up pulling a pound of freon out. Now everything works amazing!

Glad you got it worked out! But this also underscores the point of having known, calibrated gauges, that's what the pros are responsible for. Same goes for torque wrenches, but mistakes with AC can be very costly.

Nope. We pull the dash. We do it so much, we can do it pretty fast, but it still all comes out. My best ever was an hour and 5 on my wife's car, but even after doing dozens, I average 2 hours. Protip: the dash can be tilted back far enough with the console out to squeeze between and get the sensor. There's a locating pin on the left side of the center support that makes a decent pivot.

You should know that the 06-12 cars you read about with evap temp sensor problems are 100% different from your 13. Glad you figured it out, but don't base your research on what 1st and 2nd gen guys are dealing with. 13+ is a whole different animal.

I am having problems with my AC, today its 57 degrees outside and it got humid in the car I turned the AC on to cool everything down. The AC light comes on and the fan kicks on however I am not hearing or feeling the AC compressor kick on. There are no blown fuses, the Ambient Air Temp Sensor shows the correct outdoor temp, however I know that the sensor can still be bad and report the correct temp on the dash. Where should I look to fix this problem? Should I replace the sensor?
