    Default (FG) Air con issues

    i have a 5 week old fg xr6 whose air con decided to pack it in yesterday in mid 30 heat! instead of blowing cold it was pumping stinking hot air out. rang the service dept of the dealer who didnt seem to be in the know but then after putting me on hold came back saying that they had received an email that day stating that it is a known problem with the module(??). thats ok i said - when can i come in to get it fixed? we dont know when replacement parts if any will be available but we will put you on a waiting list.

    my concern is was i being fobbed off? i have done a bit of research on the net and with some friends that are car enthusiasts and have not come across this issue.

    can someone allay my fears that this is a short term issue with a simple solution?

    thanks

    If it is the module, there isn't much you can really do... I would however try ringing a different dealer, in case they are rubbishing you with the waiting list thing...

    Having car issues is a royal pain. Like anything you get it sorted one way or another.

    Ford is no different to GM/Yota/Merc/BMW/AUDI and any of the others.

    You and 99 percent of the rest of the world have car issues on a daily basis.

    JPOD and the others are spot on and are very factual.

    P.S My FG is not perfect but either is my wife.

    Could it be the heater core jpod? I had that problem with a BA XT and it was leaking water aswell. That is a dash-out job.

    a quick update - thanks for the suggestions. rang back the original dealer after trying another that was close by. got a different service technician who seemed to have a better idea on what was happening. had it in today and his suspicions were confirmed - a faulty HIM module. able to reboot it and get it operating but likely to die again in the near future so on the list for a replacement when it becomes available. apparently quite a few fg s having similar problems. ford have withdrawn a particular batch and the delay is waiting for the new batch.

    thank god the 40 degree days seem to be over!!

    Hi Tomo17 and friends

    I have a G6E which is 11mths old. I'm finding the dual climate control is "on the blink". If I set the 2 temperature controls at the same temperature, one side will provide air at around the the correct temp. but the passenger side is easily 8-10 degree hotter. You only need to put you hand in front of the vent to feel the difference.

    My dealer say his diagnostic says alls ok. But clear its not the case.

    Have other had a similar experience? and had it fixed?

    Apart from this one (hopefully fixable) issue I love my G6E. Beautiful to drive, look at and own.

    Regards

    I had the same thing hot air out of passenger and cold out of drivers. They had to remove the dashboard to get to some solenoid in there. It was a big job.

    Ok, now we are into the cooler months I find myself at 4:30am using the demister set about 22 degrees. All is good for about the first ten minutes, then it starts getting HOT and well..... too cosy! So naturally I turn the temp down to 20 degrees, and yet it continues to pump out warm air??? So I drop it down to 18 degrees, and STILL warm air!! So I change it to L, and bugger me??? WARM AIR!!!
    So I changed from demist to vents on the face, and still warm air!!!
    By this time I'm starting to sweat!!!!
    So I turn the AC completely off, then back on and wollah!!!! Freezing cold air (still set on L ) So I raise the temp back upto 20 and its just nice now, and working properly again.
    So my question is, does anyone else have problems like this with the temp control pumping out hot air even though you change it to a lower setting??

    Another thing is, the original temp when the car was started was 22 degrees, but the temp it started pushing out once the engine had warmed up, was well above that???

    Its the HIM module, they are faulty. (Should be a re-call). Talk to your dealer. They will replace it.

    Recalls are only for safety faults. A general fault warrants only a service bulletin and they fix it under warranty.

    ok, so had a fiddle this morning and this afternoon when I came home from work.
    It only gets locked on a temp setting which seams to be "roast" while on demister.
    If the car is first switched on and the vents are already selected then you have control up temp or down

    Quality!

    Its a safety issue when the air con locks on face or floor mode, (with only the slightest screen bleed). Traveling in a 100 kph zone RH lane peak hour and the windscreen fogs up...what are you gonna do.

    I have a G6E and had the same problems. In Summer cool air out of driver face vents and hot air out of passenger face vents. Took the car back to dealer I bought it from and they fixed it. Yes it was a dash out job.

    I have a XR6 FG Mk2 Falcon. If you disconnect the battery for an hour and then reconnect it and then start the engine, the air conditioner won't come on for about half an hour of driving. When it does come on, it cools down way lower than the set temperature. At other times the a/c cuts in for only about one or two seconds. Have all these Falcons got problems with the a/c?

    Refer to the quote below, this procedure is for when you disconnect a battery in FG

    When you reconnect the battery switch your ignition to on but do not start engine, wait for all the cluster lights light up then switch off ignition, switch ignition back on then start your engine, your air-conditioner should work straight away.
    FG falcons are known to play up at times with a weak battery or defective battery.

    If you are still having problems get your battery checked out 1st, refer to this post......http://www.fordaustraliaforums.com/f...working-at-all

    If you are still experiencing problems with A/C then get an air/con mech to test it.

    Second the low battery opinion the hvac needs start up voltage immediately after cranking and with a low battery from sitting baround it just blows out hot air

    Hi all

    I searched this thread because I was having trouble with my 2011 FG a/c - it was working fine, I stopped at some shops, then got back in started the car and it didn't work. A motor mechanic friend (bikes) said they have a great deal of trouble with bike computers getting thrown by tiny extraneous voltages and they give them a "hard re-set". This involves disconnecting the +ve battery leads (all of them) and firmly touching them to the negative terminal of the battery. This is supposed to drain all capacitors and leak out all residual voltages. Re-connect the leads and turn your ignition to "on" ONLY until the computer has done its boot up from zero. The car can then be started.
    I did all this and the a/c WORKS !!!!!!!
    When it first failed I went to an auto elec and he checked it and found nothing wrong in the circuitry and then to an a/c fellow who checked the gas pressures etc. Both couldn't fix the problem and said I had to take it to Ford.

    My question is does this sound familiar to anyone ?? its all too strange to be true but 3 weeks on and my a/c still works so I'm a little bemused.

    I'd love to hear from anyone who has had a similar experience or heard of a "hard re-set"

    all the best

    What I do know with the FG's is that they require a battery to be in top condition, I have only heard of resetting the ECU once from another forum member to get their A/C to work so your mechanics theory is most plausible.

    Cheers.

    Thanks PD56, this may still be an issue as my car still has its original battery (over 4 years old) and although it starts every time it "sounds" slow to an old car tinkerer. my next step will be to replace the battery so I guess time will tell!!

    Hi PD56
    I think you are either brilliant or a psychic!! The a/c failed again yesterday AND a warning message also came up on the ICC screen that the Bluetooth was turned off because of "low battery voltage". I have since replaced the battery and everything (including the a/c) works fine. I'm still a little cross because an auto elect, an a/c shop, and Ford service all failed to provide me with the information you did - and they are supposed to be "experts".

    Thanks for your invaluable assistance

    Thank you so much for your help. I am glad that someone believes me at last.
    There is also one more issue with the A/C that I doubt anyone knows about. This is because I have fitted a blue LED with a 4.7k resistor wired across the A/C clutch and mounted the LED below the Touch Screen.
    The problem is that sometimes when you start the engine, the A/C clutch comes on only while the engine is being cranked over. It does this even with the Climate Control in Semi-auto and the A/C off.
    Without the blue LED there would be no way to detect this. The system definitely has flaws because it should NEVER let the A/C clutch engage while the motor is being cranked.
    Could someone please test their car and see if it also happens? They could do this by having someone hold an LED test lamp onto the A/C clutch wire connector in the Engine Compartment Fuse Box.
    First remove the Fuse Box Cover, then you need to remove the small rectangular black plastic cover.
    Touch the tip of the test lamp onto the brass connector of the Black Wire with the yellow stripe and the alligator clip of the test lamp onto a bare metal of the car.
    Now start the car and see if the Test Lamp lights up while the engine is being cranked.

    compressor clutch can turn on when cranking.
    not tested this with FG but it does with EF EL AU so I see that FG will for the same reason. checking the serpentine belt.
    other cars use a tacho pulse on the compressor.

    during cranking the clutch operates to test the compressor or drive belt. On training course referred to checking the gas pressure reaction time.

    Also it increases the service life of the ac compressor/seals, a little while ago car manufacturers made the ac clutch engage when the reverse gear was selected to achieve the same thing
