The DCCV is controlled electronically by the electronic climate control module. You could unplug the DCCV and see if you get any heat. If I recall correctly, the DCCV opens when it is provided with battery voltage.

I will unplug the dccv first thing Sunday morning. It would be great to know the dccv is working, It does not look like a difficult repair if it need's to be replaced. I will respond back with results.

I disconnected the dccv to see if the valve's would open, It does not appear that there was any changes at all. I will replace the dccv this week/weekend . I will let you know the result's. Thank you

Oooh, I just checked my cheat sheet and I had the operation of the DCCV backwards:
No voltage is 0 duty cycle = 100% coolant flow.
Voltage = 100% duty cycle and no coolant flow.

If you haven't ordered a new DCCV yet, you may want to check for voltage to the DCCV to make sure it is being controlled properly.

The DATC controls the DCCV through the grounds for the solenoids. Connector C134 is easy to get to. It is mounted at the top of the fan shroud on the passenger side. One solenoid is controlled by the brown/green wire (connector terminal 1). The other solenoid is controlled by the brown/blue wire (connector terminal 3). the power for both valves is from the red/orange wire (connector terminal 2).

Sorry for the misinformation above. I was on travel last week and didn't have my files with me. Actually, instead of me trying to describe everything in my cheat sheet, if you'd like to send me a private message with an e-mail address for you that can accept PDF attachments, I'll forward the information to you.

I was going to purchase the dccv this week, however I did not ordered the part as of today. I should be able to check the information as describe above to see if I am getting voltage. If I have a difficult time with testing I will take you up on your offer. Thank you for the all information up to date.

Well just in time ,the temps are getting cold. I checked the voltage and everything looked good, So I decided to move foward and replace the dccv ,I now have heat. I want to thank you for all your help and knowledge that you are willing to share with all of us in this forum and making us all feel welcomed .Special thanks to Shorod for your devoted time .

Alright...I have an 01 LS V6 with no heat. Car is throwing a few codes but nothing related to the heating system...at least I don't think.

P0301B
PO316
P0430
P2195
P2197

Coolant is topped off, good thermostat, system is free from air and the heater hoses are hot, under the hood and under the dash. I removed the dash and the core is good as well, the actuator/solenoid is working, the ducting appears to be free from leaks, but the car just isn't throwing warm air. I'm really stumped....any help or ideas? Thanks

I would try to contact Shorod he seem's to be the master mind behind the lincoln, You should be able to send him an email/private message to get his responce. I don't want to give you any miss information. Good luck!

You're right, none of these codes are related to the HVAC system. For the most part, the two are not tied together through the powertrain codes (P designation on the codes you list). There have been a few posts before describing how you can pull the HVAC codes from the DATC unit. I'd suggest you search the Lincoln LS forum for the procedure and see if any codes show up.

As you're probably aware, the codes you listed are defined as follows:
P0301 - Cylinder #1 misfire.
P0316 - Misfire Occurred in the First 1000 Engine Revolutions
P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
P2195 & P2197 - I haven't found the correct system in the service manual to describe these codes. Normally I'd rely on my scan tool to define these for me....

theres a really bad vibration coming from the car when i turn on the ac, and my heat wont work ne help ?

shorod · 12-29-2008, 08:18 PM

Welcome to the forum!

You probably could have started a new thread for the vibration.

As for the heat issue, have you tried any of the suggestions in this thread? If so, what have you found?

Does the vibration only happen at idle, or even if you turn on the AC while running down the road?

Just wanted to update on my car, it was the DCCV that was clogged and causing a no heat condition. Thanks guys!

shorod · 02-06-2009, 12:30 PM

Thanks for the update. Did you get the source(s) of the other codes fixed as well?

-Rod

nomiezvr4 · 02-09-2009, 11:41 AM

Yeah, 2 of the ignition coils were bad and causing a misfire.

Hi all.....

I have the same issue.. Not heat. AC works great but when I change to heat, ONLY one vent blows warm air and the rest are cold.

I want to do the On board test but I still can find the 1,2,3 steps on doing to.. My Car is a 2000 LS...

If I have to replace the DCCV Where did you guys get it from and around how much I should espect to pay.?
