I appreciate all of your videos. You make it very easy to understand. You would make an awesome teacher

[@tecmotiondyno]

I appreciate that. The objective is to provide a useful and accurate tutorial, so it’s good to know it’s working! Thanks for watching.

[@ef9087]

totally!

[@kevinthomas1253]

Love the video, and no screwdriver and hammer used to clear the light!

[@tecmotiondyno]

Thanks Kevin! I know this kind of niche tech video isn't a channel-maker on KZbin, but I think it is important to have this kind of thing out there for reference, as these cars ARE going to continue into the future. Thanks for watching!

[@ef9087]

Great walkthrough! It's one thing to read on the forums but another to see the sequence and flashes. Thanks for doing these videos!

[@tecmotiondyno]

You are welcome. Thanks for watching!

[@7777Lace]

Yes, thank you. Also, where’s the description list please?

[@tecmotiondyno]

Missed this comment. The list is actually in the video itself.

[@ILYMAD66]

Thank you so much for this and all your videos. I really appreciate you!

[@tecmotiondyno]

This Lincoln stuff is kind a niche thing, but it seems important to leave a record of how to deal with it somewhere. Glad it is helping and thanks for watching!

[@ILYMAD66]

@@tecmotiondyno yes indeed! I commented on one your vids and follow you also a while back but I have a silver 90 lsc that I Want to get back on the road so I’m learning from you!

Can someone please do a video on the air conditioning airbox assembly, blower motor, or the Climate control box for the 89 Lincoln mark VII

[@jameybarisoff]

Is there a procedure for the 97 Lincoln Mark VIII?

[@tecmotiondyno]

I virtually guarantee it, but I don’t know what it is off the top of my head. Try a google search, or better yet a service manual for the car.

[@jameybarisoff]

@@tecmotiondyno Turns out that there is tests but you gotta ground terminal 2 of the evo test connector with a test light and it will go into a bunch of tests but there is no way to really know what is going on. If it stops on a certain test then it failed. There is a thing called the New Generation Super Star II tester which who knows where you can actually get one at a reasonable price. But that will tell more info.

[@tecmotiondyno]

For OBDII era cars shop grade aftermarket test tools like the snap on tools will likely perform the suspension diagnostics for you, and you can often buy them used on ebay or other buy/sell sites for a pretty modest outlay. You do need to make sure that the tool you buy has whatever licenses or modules are required for your specific application though.

[@7777Lace]

Can you please give the link for the test descriptions?

[@tecmotiondyno]

I included them in the video itself. You should be able to pause the video to read them

[@7777Lace]

Yes, I saw them & thank you very much Sir for your very informative video & taking the time to respond to my question! I have a 1991 White Lincoln Mark Vll, w/ 78,000mi & I LOVE THIS CAR!!! I finally ran the diagnostic test & it went through every test & passed, except the individual solenoid tests. Because my front driver’s side solenoid didn’t vent & the driver’s side front end continuously goes down overnight. So, I just purchased a new solenoid from “Suncore” & also a new air suspension pump motor w/ the dryer & I installed it today, but after a few hours the front went down again. So, I soaked the entire bag with soapy water from top to bottom & I sprayed the top of the dryer & I did not see any bubbles & the bag is rock solid. Do have any suggestions as to what is causing this & what I can try to determine the problem? I’d really appreciate it, because I don’t want to burn out my new pump motor!!😳😩

[@tecmotiondyno]

@@7777Lace It can be the o-rings on the solenoid - if you don't use dielectric grease on them when you install the solenoid they can roll over and leak. It can be the air line itself - if the end is damaged you can razor blade 3/16" or so off the end of the air line where it goes into the pushlock. It can be a bag leak at the retainer clip under the bag if it has been damaged there. Those are all things to at least check.

all i ever seen from theses cars were parts for the fox bodies.. even back in the day they were way over engineered.

[@tecmotiondyno]

I sure thought the same way. My 9 second Fox still has Mark VII front rotors on it, which was the easy old school way to convert to 5 lug for example. Now that I own one, I prefer it to a Fox Mustang as a nostalgia cruiser.
