Lincoln LS Climate Control



  • lse4melse4me Posts: 12
    LOL!! I was just going to post about this subject because this just started happening with my 2002 LSE.

    Since I mainly drive this vehicle alone it's not that big of an issue as one option is to close the vents on the passenger side. However, went on a trip with wife and daughter recently and wife got obsessed with it.

    We are planning another trip soon and she wanted me to get it fixed. Happened just yesterday on my commute home in 95 degree weather. I try turning the A/C off, changing some settings, running the desired temp up & down. Took awhile this time but eventually got cold air again.

    Since Bonnie already had it checked out at the dealer with no success, I don't know that my local mechanic would be any better (nearest dealer is 45 mins away).

    Anybody else had a successful repair??

    Yep. Happened to me. It sounds like the DCCV (dual climate control valve). The part was, IIRC, ~$200 and a couple hours of my labor. If you're handy with a wrench, it isn't too bad. If not, would have the dealer, or competent shop, do it. Alldata says 1.9 hours labor.......
  • Please send me some help, On our 2000 LS the passenger side temperature will fluctuate somewhat but will not turn off, would someone be able to diagnous our problem? Thank you.
  • hi i am a mechanic and i know what the problem is but im not sure how to do it on the lincolns i have one to but...any ways the problems the resistor it allows the controls on the center console to lower the level by adding resistance to the circuit. im not sure where it is located but it is usually located underneath the glove box on the passenger side. hope i helped
  • id replace the temp sensors on the dash and id replace the temp. controls on the center console i know it sounds unspecific but i had the same problem but i replaced both and that fixed the problem
  • Did you figure out what your "not heat" problem was? I have a 2000 LS with the same problem. I changed the theromstate...not improvement.
  • did your no heat issue require replacing the thermostat? how did you get the issue resolved?
  • have you resolved this issue and how did you if so?

    Hello,I have a 2000 Ls,The weather has been about -35 and for some reason i started my car this morning and i ran it for about 20 mins and jumped in to drive to work and there wasnt any heat coming out of the vens.the gauge for temp was right where it should be and i poped the hood and the rad hoses were all hot but still no heat,so i got back in and reved it to about 2400rpm then the heat started to come but when i let off the gas the heat goes away.the motor is a 3.9 V8 if anyone could help me i would love it,Thanks

    Hey guys,No i havent heard from the dealership but he told me it might be a head gasket becuase my rad hose didnt have pressure,he thinks its sucking air from there witch i find crazy that he would jump right to the head gasket and not try anything eles.
  • Have you ever figured out your no heat problem? I purchased a Lincoln LS this last fall and found out that once the outside temp gets down in the teens or lower, it simply doesn't heat or gets lukewarm at best. I spoke with two other LS owners and they have the same problem. The engine temp always comes up to the half way mark on the guage and stays there rock solid. I would expect if a head gasket really was the issue that the engine temp would fluctuate. If you have found any way to resolve your heating problem, would sure love to hear about it!!
  • I have same heater problem with my 2000 LS V6. Anybody come up with the fix for the lack of warm air? Thanks for any ideas, especially proven ones.
  • rgnmstrrgnmstr Posts: 226
    I have this same problem on my 02. No heat at idle or when coasting but plenty of heat with my foot on the gas.
  • I have not had any luck yet getting my Lincoln LS to heat during idle. My brother and another individual I know both have the same problems with their Lincoln LS as well. Hopefully someone can tell us if there is any way to resolve this as it appears to be a common issue.
  • I have finally fixed the problem with the A/C turning HOT on the Pass side. I'm leasing a new Chevy Impala and sending the Linc to the next owner. Too many heat/A/C problems for an expensive auto that no one at the dealers wants to fix.
    I'd buy another Linc but with the price of High test I looked for a regular gas auto, and some Impala owners say they get 45MPG on the open road. That's where I do most of my driving. See ya in the funny papers...TFC... :lemon:

    45 MPG? Maybe they're *drinking* high test?

    New Impala looks pretty nice. Hope you have good luck with it!

  • Check out the answer on Intermitate Heat on the forum.
  • I have an 02 Linc LS and can't get any heat, blows cold air only. I have heard it may be the evaporator duct sensor under the driver side kick plate. Anyone heard of this issue?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Well before you get into such HVAC controls, try the simplest things first and check your coolant level. Low coolant = no heat.
  • akirbyakirby Posts: 8,062
    The thermostat could also be stuck open.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Well in that case the engine would be running abnormally cold and in a very cold climate I would think. Even completely open, he should get SOME heat. Modern engines run pretty warm even with full-open stats, don't they?

    But it's a good point. I wonder what his temp gauge is reading and if that reading has changed from "normal".
  • The temp guage on the dash comes up halfway, just as it does in warm weather. If it was a thermostat, wouldn't I expect the temp guage to read much cooler?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    That's what I would think, yes.

    so you're thinking (presuming coolant isn't low) that your automatic climate control is sort of stuck into thinking the car is already warm inside?
  • akirbyakirby Posts: 8,062
    In that case it does sound like either the heater core (or hoses) or the HVAC controller.
  • That heating /cooling problem on the lincoln ls aint hard to fix. its just most people dont understand the system.there easier to fix if you know what and how to do it.
  • i just bought a 2000 model wasnt heating at all just cold air .well some one tried the thermostat and it done no good long story short these heating systems aint hard to understand there is a relay that opperates to pumps to the heating system its under the hood start buy checking it first check your fuses if there good check the the two pumps under the hood they are mounted on the right side of the fan shroud they cant hardly be seen because of the hose and the round a/c tank.them pump will somtimes freeze up take a test light check the power too the motors if you have power you can take the motors out and bench test them there are several hoses that run in and out of these two pumps make sure you mark them. so you dont get them mixed up but after you bench test them if the motrs dont make any sound the your problem is there.and make sure you have plenty of coolant in the system.sometimes if your too low on coolant they will not blow heat.dont get discouraged with the heating problem these seem to be good cars you just need to look the whole sytem over and understand how it all works. and if you can do that you will soon fix the problem.and YOU DO NOT HALF TO TAKE IT TO A GARAGE.
  • check the dual coolant pump and the auxalry pumps they will freeze up or stick mine were bad trip to te scrap yard 20 dollars later and 2hrs or so i have heat.

    check your relay and your fuses for the heating too could be somthing simple.and your coolant level.
  • Thank You so much for the info on the heating system on the Lincoln LS. I have had the system flushed and new coolant added, so if the problem was the coolant I should find out soon. I do have heat now at 90 degrees, and cold air at 60 degrees on the manual override. Unfortunately it turned off warm (55-60) degrees and the auto doesn't want to blow heat because it is too warm outside. Temps are supposed to drop next week, so I should find out for sure if trouble is fixed. I will deffintely check relay and fuses if i still have a problem. Thanks Again!
  • I have a 2000 Lincoln LS, and recently my a/c & heat aren't woking. My blower motor and fuses/relays are all working, but when i click my climate control panel, nothing happens. Is there anything you can tell me about this?
  • I know the fuse panel is in the trunk, but i do not have an owners manual, so i need to know what fuse controls which circuit, help?
