Anyone experienced anything similar? I was riding along and adjusting the AC temp level on the steering wheel of my 2004 Lariet and the AC shut completely off. I turned it back on but had to stop shortly. When I came back out and started home I noticed the AC was not getting cold but air was blowing. I checked all fuses when I arrived home and all were good. I restarted the truck and the instrument lights on the AC panel started blinking on and off. I turned the truck off, restarted it and magically everything worked like it's supposed to. No problem since. Should I be concerned?

 

Electrical Gremlin. Hopefully a one-time deal. If it happens, note when/how and the date/time. Keep a log & look for a pattern. Take it to the dealer and share your info. Dealer might have a little problem trying to find an intermittent gremlin. Good luck.

 

WHO YA GONNA CALL ?????? sorry ya kinda left it wide open for that...

 

I do not have a Lariat, so I'm not sure about this. But do the Lariat's have Automatic Climate Control? You set the temp and it will automatically go to that? If so, once it reaches the desired temperature, the air temperature coming out of the vents will compensate to keep it a steady temperature inside the vehicle.

 

You are correct, but the behavior he described isn't normal. The system doesn't shut off on its own nor should the panel 'blink'.

 

Well if you want to get technical...

 

I have a Lariat and have had lots of issues with my EATC system, at times my A/C will shut down (off) within a few minutes of driving away? also the A/C will not stay in the Max A/C mode, it will switch to normal A/C after a period of time. I ran the "Self-Test" on my system a number of times and found no condition codes? Being a Ford Dealer Service Mgr. I am watching for "TSB"s and "SSM"s for any data from the factory...

 

I've had the same issues. System shutting off a few minutes after starting the truck, temp set to 68 then rocketting to 75. What gives?

 

Using the search button on this site reveals that most A/C problems are resolved by having the PCM reflashed.

 

slvr answered part of a ? i have. my fan speed is the same low on 1, 2, and 3, the blows like crazy on 4. i have the 1714 tuner, never been reflashed and didn't have a problem with install. should i return to stock before i go to dealer and expect to send tuner in for an update?

 

If you think that the dealer might be re-flashing your PCM to fix that problem, then DEFINITELY return your truck to stock before taking it in. If they reflash while you have one of the Superchips tunes loaded, your MicroTuner can become "locked" when you go to use it again and you would need to send it to them anyway. If they re-flash, you'll also want to save that revision as your new stock program (it will be just like using the microtuner for the 1st time on your truck after the re-flash). Hopefully, the microtuner won't have any issues with the re-flashed PCM program.

Good luck,

 

I had the same problem........A/C STARTED BLOWING WARM AIR ..I CALLED THE DEALER TO SCHEDULE AN APPOINTMENT AND THE NEXT DAY STARTED IT UP TO TAKE IT IN TO GET REPAIRED NONE OF THE INSTRUMENT LIGHTS WORKED.THEY ENDED UP REPLACING A MODULE I BELIEVE FOR THE A/C UNDER THE HOOD
