Thread: 9-3 AIR CON PROBLEMS (09 9-3 stopped blowing chilled air)

    9-3 AIR CON PROBLEMS (09 9-3 stopped blowing chilled air)

    (MADE AS A STICKY FOR THE HOT WEATHER UNTIL THIS CAN BE MODIFIED/SORTED AND SIFTED THROUGH)

    Today of all days on a long journey, it was time to put the roof and chill the car as the sun was to strong. BUT the cabin air refused to chill....did work, and just. Stopped like that. IT MAY be linked to having the car serviced ( just a thought ) any ideas on what to check. Air is blowing but it's not chilled.

    AC turns off when hood lowered - a green light on 'AC Off' button indicates AC Off. You can turn it on manually bt pressing same button - light goes out.

    Did that mgb, it's not playing fair, just moving warm air had to crank all windows down as passengers in back were complaining of heat.

    Re: 09 9-3 stopped blowing chilled air

    I suspect you are low on gas, either its just low as they do need topping up from time to time, or you have a leak in the system the most common cause is a stone has punctured the aircon condenser

    it is also worth while checking the clutch engages on the compressor

    don't just have the system refilled...........if you have leak the gas will just escape so false economy £ wise

    the best option £50ish is to

    evacuate any remaining gas this will also remove the pag oil
    vacuum of the system 20mins min this will remove any moisture from the system (death to aircon)
    after vacuuming the system the machine will do a leak test
    refill with the correct quantity of gas and oil along with a dye which will pin point any leaks under uv light

    Thanks for the Kez pretty comprehensive list that. Had a quick look this morning (I dont use the car for work) and I noticed that the LED on the "auto" button is not working. but the button does work as the fans change pitch when I cycle it. Nothing obvious under the bonnet, I did see a mention of holding the auto button, and aircon off switch together (dont know if the relates to my model) however it didnt do anything. I suppose next stop is a garage. Cant manage without that aircon (well I can but its not good as we found out yesterday)I cant sense a change in engine note when cycling the aircon off button. (but then I cant honestly say I did notice it.) So I dont think the clutch is engaging the compressor.

    if it is low or no gas the a/c wont turn on, when was last time you used was it ice cold or have you noticed it getting warmer air over a while.

    ring round a few aircon specialists get a few prices first. tell them your after a recovery and recharge with vacuum

    Re: 09 9-3 stopped blowing chilled air

    I've had the car about 18 months (ish) and I have never been happy about the cold air from the day I
    Picked it up compared to my 2 previous vehicles. Since Feb I don't think it has done 1000 miles as I have a contract where I walk into work. I have been put in touch with a guy who specialises in Aircon, apparently he will charge 50 quid for a pressure check flush and re gas, and will come to me. Ill let you know how I go on.

    @[email protected] had klaus Ward out today who operates a mobile service in Hants Diagnosed a leak on the
    Condenser right were the vain meets the main body. Probably due to corrosion of the alloy rather than a stone chip. 250 for the job all in which I am happy with considering some of the dealer prices I have
    Heard quoted. Part ordered being done next Monday. Auto Aircon 07973 252531.

    Sorted then ..............at least you not chucked money away just having regas that would have vanished into thin air !! tbh for the extra £20ish for a service is money well spent and imo a regas is just false economy thus this is the reason we do not do this in work

    I was gonna say the rad as that's what happened to mine. Got a really good price all in there as I did mine myself and cost me about £160 (£120 for the rad, £40 regas) - Been 2 years as it's still cold as hell, love it - best a/c ever. I also fitted some mesh behind my grill when the bumper was off to stop the chances of any large stones damaging the rad in the future.

    Re: 09 9-3 stopped blowing chilled air

    Another update, new condenser fitted, regassed (obviously) but the car is still not blowing cold air. Klaus has changed the pressure switches, checked the clutch, cant find any issues. He can start the aircon using his "probe" and it runs and chills the car, but wont start from within the car (fuses have been checked). I am going to try a calibration later. See if that resolves it. What we both noticed is the LED on the autobutton (on the passenger side) is not working. (It was up to Sunday) thats not a sign of a fault is it ? Anyone any ideas ? If that wont cut it, then its time for a garage, and more money.

    Re: 09 9-3 stopped blowing chilled air

    below that button is a switch for aircon off check this is not lit

    if you press the auto button does this light then come on ?

    another quick check go into settings on the sid go to climate settings and check aircon is on or auto your manual will guide you if you don't have one let me know and will post up for you

    then let us know how you get on

    Cheers Kez, just been to the car myself to check it out, all the above criteria has been met. Still no chilled air the man said he has done loads of 93 and 95 and never seen this before best he can suggest is an
    Electrical fault IE a broken wire. Disregard the auto LED it works, just me being a numpty. Bear in mind he said he can fire up the aircon with his gadget and it chills the car. He has checked everything he can. Even got an aircon service sticker under the bonnet but no chilled air to the cabin. @@[email protected]@

    Looks like its going to be a Tech 2 garage job, just on the off chance does anyone know where the aircon control module is located ?

    Re: 09 9-3 stopped blowing chilled air

    Still pursuing this on other boards as well as this, not getting far.
    Learning lots about Aircon though :-)

    Best link of "how it works" http://www.swedishwrench.com/saab_ACC_part_2.htm

    (read the part 1 ) So, best I can come up with at the moment is I have no fan action on the front of the car when I turn the aircon on, Still think I will have to Tech2 diags it tho, but just for the moment it will have to wait, I have thrown to much money at this car last week, with 12 months Tax, and 275 bill on the aircon. In the meantime if anyone has any ideas please feel free to give your input.
