Lincoln LS Climate Control



  • themacguythemacguy Posts: 417
    our '04 LS was just blowing unholy hot air after a brief overheating episode in mid-december, in which i replaced that multiple piece thermostat thingamajiggy (what a p.o.s.). fixed the overheating, but no effect on the a/c until i got a magnifying glass after the little tinker-toy 10 amp fuse under the hood. note: i'd been looking at the one by the spare tire, but never had looked at the (obvious) box under the hood. doh!

    yep, it was fried, but not noticeable with the naked eye. anyway, after 5 months of 'sweating' the daily commute, it's fixed! hallelujah, praise God! we live in w. tx. and it's hotter than the hinges down this way... anyway, i just came over from the dakota board, and when i saw this thread (and read it carefully), i got the gumption to go out and fix the stinkin' thing. thanks for the thread! now i've gotta find a black hood and new windshield for it since we left for the ranch last weekend, left the car out and baseball size hail got it (plus the roof on the house). man, that hailstorm was nasty!

    I am having problems with my Heat and AC. The heater will not blow any heat at all and just before it stopped I would hear a loud roaring noise while the car was running. Then soon after there was no heat. And the AC compressor will not come on. Any help will be appreciated.

  • akirbyakirby Posts: 8,062
    Hey Paul - I think that may be the HVAC controller instead of a compressor problem since it affects both the heat and A/C.
  • Does anyone have a picture of where the A/C low pressure port is? It's starting to get hot outside. Thanks.
  • Does anyone have a picture of where the A/C low pressure port is on my 2003 Lincoln LS 6 cyl? It's starting to get hot outside. Thanks.

    Can anyone tell me what I need to check and where. My compressor was not coming on, got that fixed ( a wiring problem) now when I drive the car with the AC on it runs hot. But I notice that when I turn on the AC the cooling remains at the same speed. Does it suppose to run at a faster speed when the AC comes on?
    It was not running hot at all until I got the compressor fixed then it ran hot the same day. I am not running the AC right now. But the AC does not seem to be as cold as it should either. Any help will be very much appreciated. I see this to be a very good and helpful forum. Thanks in advance.

    Just took the drivers side tire off on a 2001 LS V8 and no black rubber flap.

    Can anyone help me locate the low side AC port on a 2001 LS V8?

  • themacguythemacguy Posts: 417
    temps are hitting 100, and now the a/c is back to 'waffling.' it will run hot out - either - one side - or - the other. after a few days it will run normally. then just hot. it's got to be a sensor, connection or a computer somewhere that's misfiring somehow, though it will run normally (cold) for several days running.
    i've been told there's a connector underneath the electric cooling fan setup that could be the culprit. there's a center pin that you can apparently read with a simple multimeter. if it's got juice you're okay, if not, then it's a bad board. does that sound correct to anybody here?

    You need to jack up the drivers side of the car. remove the plastic cover that is covering the compressor.It is next to the oil pan on the engine. The low side port is on the compressor.

    I have a 2000 Lincoln LS with an ac issue. When i turn the ac on the clutch does not engage.I bought one of those refrigerant refill kits with a gauge and it says that the charge is good. could this be accurate if the charge is low? How would I engage the clutch to add refrigerant?

    Any help would be appreciated.
  • Can anyone tell me how to remove the electrical plug at the DCCV. It seems that the red tab pulls out and then the plug should disconnect. But it doesn't seem to want to do that?
  • Got it! What a royal pain in the A$$! Apparently, from I can guess, the red clip is a lock. Push it out (can use a screw driver from underneath). Then push in on the black tab that was under the red clip and gently pull the plug out. You squeeze that black tab into the plug.
  • Can anyone help me out? The A/C on my 2000 LS V8 will periodically stop blowing air. When this happens, the message center beeps and says that the passenger door is open. I turn off the air, wait a while and eventually it will start working again. Is this a sensor or fuse starting to go out? PLease help.
  • i recieved error code 19 47 for my ac which has been having the same problem as everyone else....runs cold on 60 degrees hot on anything else.
    cold on drivers side hot on passengers side.
    well its done now! all hot all the time with error code 19 47.
    i found on internet that this means Evaporator Discharge Temperature Sensor circuit is bad.
    Any ideas if this is true and if its hard or expensive to fix?
    ANY info would be appreciated. I live in FLA and cant take this heat!!! but cant afford to fix one thing and have it be something else.
  • ours has started working normally again w/ 50k on it now. the a/c is working normally that is. since we put the car up for summer, the battery died. replaced it and now it won't run properly in the second overdrive gear (5th). we run it in 4th to keep the revs above 2k so it won't shake going down the road. i'm guessing one (or more) of the cops (coil on plugs) is getting 'oily.' the check engine light, once flashing, and then just on steadily for a few months, has now gone out completely.
    my 2000 dak quad cab, which i've documented since new on edmunds, has 165k on it, with a lot of heavy abuse miles (offroad in the dust and lots of heavy towing) in the oilfields of west texas. its check engine light came on at 8k miles, has been on ever since, but nothing's really ever ever failed on the truck - runs great all the time. amazing difference in the two vehicles, and the dodge cost about 1/2 of the lincoln's $45k. both bought new. both maintained extremely well. go figger...

    Wow. You've driven a truck for 157,000 miles with a check engine light on? Couldn't the dealer have fixed it under warrenty? :confuse:

  • yes i have driven it hard (no time for dealer/warranty work though), and i've done the same thing on my other dakota. it's a common problem to them, as something as simple as an open gas cap will trigger it. which was what caused mine, anyway.
    it's not uncommon for somebody in my business - oil and gas fieldwork - to drive several hundred miles per day, seven days a week, with no vacations for years at a time. then, NO work for many months to several years afterwards. it's not nearly as glamorous as most of the nutty media and even crazier politicians would have you believe. they only look at all the money we make when we're working, but they disappear when we're in a bust cycle. at the time my dak's engine light came on i was driving over 150 miles per day, 7 days a week - just commuting. try that out sometime. after consulting with my friends on this site (the dakota board), i figured out the problem with 'bpeebles' 'bookitty' and others' expert advice, and i haven't looked back.
    so, no worries mate...

    Hello Everyone,

    I'm seeking some advice. I have a 2000LS in which the heater stopped working. AC works fine. the blower works fine, but when I adjust the temperature hotter it still blows cool air. The car has been warmed up. I took it to my local mechanic who I trust however he says the door on the heater is not opening and it will cost $700 just to get to the heater and figure out whats wrong. My question is this a problem that a local ford dealer or lincoln dealer can handle better and cheaper or will it be a wash either way. Thanks.
  • akirbyakirby Posts: 8,062
    It could be the blend door and they are expensive to fix. I'd get another opinion and quote from a Lincoln dealer who has seen these before. It could also be the controller.
  • i did a self diagnostics (reset) test and you can hear all the doors adjusting opening and closing. after i did this a few times the air/heat started working properly again.
    it is posted on this site how to do the test.
    i would try that least its free!
    i cant remember exactly so i would double check but i think it was to
    push the panel button then quickly hit the off and auto buttons.
    you can hear it testing everything
    the first time i did it it gave code 1987 but i did it two more times it started working again fine.

    it said 88degrees - ext -188 degrees
    may be worth a try.
  • The DCCV - Dual Climate Control Valve on your car is bad. You will have four heater hoses running to it. Take them off and clamp them, if your ac is restored than you know for sure this valve is bad. Its under the hood on the passenger side of the car. Can't miss it.

    when i turn rear defront buttton on and even crank the air speed nothing comes out the back vents, the back wondow stays foggy everytime any ideas?
  • akirbyakirby Posts: 8,062
    Rear defrost heats the glass via the metal wires embedded in the rear window glass. There is no hot air involved.
  • My 04 LSE only blow out hot even at 60 degree selected. It started out with the passenger side blowing out cold air and then the drivers side blowing out hot air for a day or two then only hot air. The climate control seat with just fine.
  • MY '05 was doing the same thing, the temp would never change. I took it to the dealer and it ended up being a water diverter valve that had gone bad. Once it was replaced it worked fine, luckily I was still under warranty. With the amount of issues I have had with this car I am seriously thinking of getting the extended warranty from the dealer for $1200 for an additional 3 years of coverage.
  • Hey Jokersmith
    Thanks for the info, do you know the part number or correct name for this water diverter valve. I tried looking this part up on and no luck.

    Are you guys talking about the DCCV (dual climate control valve)?
