If the compressor has seized or is making noise, then definitely you must change the entire system---otherwise, if the compressor is not damaged, you might get away with just a compressor and a dryer and perhaps flushing out the AC hoses as long as you have them off.
I've done this and gotten away with it.
You can inspect the interior lines and dryer and see if there is debris evident and go from there.

2000 lincoln ls blowing hot air intermittently from passenger or drivers side with A/C on. Replaced DCTV, but problem persists. Blend door or maybe some other cause?

It was the blend door actuator on my Lincoln...cost $35 for part. But I was only getting hot air and of course that was mid summer.
#107 of 155 climate control heat only after adding freon and ext temp high
May 24, 2010 (10:40 pm)
Vehicle is a LS 2000 v8 3.9 160k great car really. other than the trunk space, and cup holders in the front that hold nothing but bottles of water if more than one things.
I have a new thing for me. Yes it relates to my blower but it is not just a one side issue.
A quick summary. as of last week it would work fine up to like 75 80 then blow warm sometimes .
So my mechanic suggested adding the freon equivalent stuff .. a couple of cans. it actually ended up being 3. Now the interesting thing was after starting it it now only blows hot.( i mean I can pry cook an egg. well at least keep a latte warm) It does not matter if the a/c is pressed on or not. set at 65 or at max it still blows hot. maybe some slight changes but still hot.
When I run the climate control self diagnosis it goes through all of the 25? i think steps at the end it does not show any codes just shows all 8's or illuminates the other tings on the display.
You can hear while the test is running the different flaps I assume opening and closing.
Now for the unusual. I notice there is a high pitched whistle when the A/C is turned on. you can hear the compressor I assume click on then you hear this sound. now it does get a bit louder of a whistle sound as you start to accelerate. After you turn off the climate control or a/C button it continues for awhile. OF note 2- The outside temperature seems to be set now at 82-95 degrees on average.( when the car was turned on I did try the code dianosis when the outside air was cool( 75 and the display read 82 external. the dx with the off/ foot blower at same time followed by pushing auto in 2 seconds shows the same display all 8's .. When doing it when the car was just turned on before the ingition it ran up to show the outside temp at 107.. The car other wise is running great. the thermostat for the engine shows slightly below middle where it always rests.
Is it possible when they added freon stuff that it pushed out some muck in the line that clogged the hoses? could it be just taking of the hoses and cleaning or changing them?
Open to any ideas. It was suggested it could be my display climate control panel but i do not think that is the case.( i do happen to have a back up one just in case on hand )

Since you used your mechanic to remedy the first issue and now there is more of an issue. Honestly, it's time to take it to the dealer for diagnosis now. The Lincoln Ls can be a mystery sometines for mechanics but the dealer can nail it down to the detail. This would eliminate any further good intentions efforts by your mechanic that may or may not be a good idea.

Thanks for the advice. What all did you have to repair earlier this month after yours did not work since it was similar?

In my case the dealer told me I needed a new compressor because mine was leaking. Supposedly commom for the Ls. Along with the compressor were supporting components that had to be replaced which were the accumulator, o'ring and coolant control valve or called the evaporative control valve as well. I was told the way this system is designed, not replacing those supporting components could damage a new compressor. The dealer was talking $2000 for this, yeah right. I went on Ebay and found a remanufactured compressor for my model for $175 and the supporting components for about a total of $50. My mechanic installed all including freon for $200 labor. Ebay also has used Ls compressor from about $60-100 bucks. Just make sure if you decide to shop on Ebay to make sure it's the right parts for your model. This can be reassured by contacting the seller of an item.

Hi Micheal, I'm having this problem with different temperatures comming from pass and driver side. Cold air from passenger side and hot air from driver side when trying to drive with the a/c on. I'm pretty sure it's the DCCV that needs to be replaced after reading so much about it, but my question is, is the dual climate control valve the same as the dual coolant control valve the same as the heater valve? are all 3 valves the same valve? I want to change the same valve that you changed on yours a couple of years back, so if you can send me the part number or exact name so that i can buy from the dealership that would be great. I have a 2002 Lincoln LS V6 3.0L. I tried asking the dealership for a dual climate control valve and they had no idea what it was because thats not what it is listed as in their system. Sorry for the long message, really in need of some help. Thanks
