Ford Crown Victoria/Mercury Grand Marquis Climate Control

1235

Comments

  • I have 2007 GS. I don't have zone climate control. This car has 3 actuators, 2 are located on the fire wall, the blend door is inside the the plenum chamber. Getting to that one is expensive , 900.00 in Las Vegas(checked 3 shops). The others are much cheaper to repair. if you have zone temp. you may have 5 of them. I gave up, went o a ford dealer, they had it done in 1/2 day. Independent shops charged as much so I went with the dealer. Hope this helps.
  • I have a loose black plastic insert covering the fog lamp hole on the drivers side. I think there is a post that it snaps onto on both sides. But one of the posts broke of and is stuck in the hole cover. Has anybody had this problem, can it be fixed at home, or is it back to the body shop . Thanks.
  • Ran the self test! Where do I look up 024 error code?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,596
    024 is blend door failure/blend door short.

    If you don't see a broken door or broken linkage, then you'll either have to sign up at www.alldatadiy.com for $26.95 for the year to get the clothesline-long set of instructions on testing for electrical shorts, or you can take a flyer and replace the EATC module which is about $90 bucks.

  • I got the dreaded 024 error code on the EATC, and I can see the blend door actuator trying to move. Just tries to move and makes the clicking sound. I have no fan, no heat, no ac- compressor not activated. Do you think a bad actuator could hang up the EATC so that nothing works? Hate to replace the actuator if it's something else. EATC display is normal and runs the diagnostic OK. Anything else to check before ripping out the dash?
  • Looks like EATCs fail a lot. I found four pages of EATCs, EATC repair shops on EBay. Anyone have a repair shop to recommend? If the failure is electronic, not just vacuum related, can they be repaired? I suspect most problems are fixed by replacing O rings, but mine is electronic. Is the dealer the only way to go?

    My unit's display is normal, self test shows 024, no ac, no heat. If I had just a blend door actuator failure, I should have normal fan, ac and heat operation- just a malfunctioning blend door or malfunctioning vacuum operation. I just ain't got nothin! Just normal display.

    Ideas, please. Hate to buy a new one if the old one ain't broken......

    I read bigmerc post about using a vacuum hose and a tee and connecting
    the black to the blue and white lines. How do I get a hold of bigmerc to discuss this further with him. If he or twocassels or lilborther would contact
    please about this. Ed
  • In the big shop manual for my 2004 CV there is an alternate control listed for the heater /AC system; used in cop cars. It is reputed to be a simple manual control. Just the kind of thing to fix the problem permanently I would think. I can try to dig out a Ford part number if fellow users want it. No idea if any conversion plugs etc would be required. I think not; at least if the Ford engineers are not completely off their rockers.

    tell me more! My '05 Merc Marquis messed up the other day, when temps on road hit about 90. Works fine in moderate temps...
  • I am interested in that part number. tired of not having air in my car. Thanks

    Here is the Part # F8AZ19B888AB Ford Switch Assy Pretty sure from item on Ebay; Item # 261007794496 brand new for 24.47 + 7.99 shipping. Let us know how it works. There is an exploded part drawing on the listing & the list of compatibles looks right. If mine gives the slightest trouble OUT IT GOES. Also seems to need a Damper Door Switch, probably knobs too.

    can you determine if your AC compressor clutch is engaging when you turn the AC on? Perhaps a friend can observe the compressor while you do this.

  • dmciverdmciver Posts: 3
    the a compressor engages and disengages,
    the a c lines are cold,
    the heater blower motor works fine

    just warm air
    this car does not have the auto temp control

    guessing maybe a blend door issue?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,596
    Possibly but you should feel cold air at the blend door, or in the ducting. How 'bout a bad expansion valve, if your car uses that type of AC system.

    If the compressor is cycling on/off then refrigerant is flowing.

    Having a problem with a 2008 Grand Marquis, when the rpm is about 12-1400 my A/C works fine ,blowing out the front dash, the minute the RPMs go up over 1500 the air flow changes from the front dash to the defroster vent,does anyone have an idea why this happens,and what to do to fix this problem, thanks
  • wwestwwest Posts: 10,706
    Ford uses a vacuum servomotor to route the airflow, loss of vauum causes this.
  • efastmanefastman Posts: 3
    I could use the pictures,thanks

    Bobe21,

    I know its been a year since you posted this, but was just wondering if you resolved this. Same exact thing happened to my friends car today.
  • I have a 2009 Mercury Marquis and I just had a new control head installed to find out there was a problem with my blend door actuator. I had A/C on my dash and in the floor before this journey started. I wanted A/C to come from dash vents. Problem solved, but now I have no A/C on my dash or floor w/o pushing a button. I dont remember if I should have it coming from every vent with Max Air button.

    what was the fix? Our crown vic keeps switching from A/C vents to heater vents
  • cheapfix3cheapfix3 Posts: 3
    what part did you buy ? My A/C keeps switching from air vents to heat vents
  • cheapfix3cheapfix3 Posts: 3
    did you get a fix?-- I have a similar problem
  • My wife's 2008 Grand Marquis LS has same problem. But I can't find the vacuum control motor for the panel air. I would tie some fishing line to the lever and pull it open manually if I could. I did a climate controll self check and the DCT's code reads 888. From what I have researched, it must be a vacuum problem. It's 104 here in southern Indiana and I need to get the panel air door open fast! I can find a couple hoses coming through the fire wall above the pedals and confirm there is vacuum.

    1998 Mercury Gr. Marq. LS trans. shift down button on shift lever does not actuate the transmission to go from 4th to 3rd and no light or signal comes on shift selection on dash. Checked fuses on dash and under hood. Added a quart of TransX to transmission. All works well but will not shift down on mountain grades. Car only has 60,000 miles and was garaged but little old lady did hit curbs and wonder if she may have run over something to pull wires out of sensor somewhere.
