iv done everything up untill 9min 25sec i have the same truck when i jumped my compressor it started pumping when i put the relay back in the truck and started the truck the compressor wouldnt turn on and im still getting the service suspension on the dash i replace all fore shocks and compressor everything works when i jump it but doesnt when i start the car i also cant talk to the electronic suspension control module with my scan tool to allow me to test run the compressor could this be my module that has gone bad????

After chasing wiring and getting ready to pull the trigger on a new compressor, I thought let me watch a video on this. I found this video and less than 3 minutes in you had me face palm myself for not starting simple and checking fuses! Thank you sir, you saved me a ton of time, and money. The fuse wasn’t even blown, it had just wiggled loose. Thank you for the straight to the point video!

[@FarmDad]

Glad it helped! It's easy to forget the easy stuff.

[@castorriverhideaway1347]

Thank you for the video. We bought a very neglected denali that has 194,000 miles. It still had original equipment suspension. Shocks were blown years ago and who knows about the compressor? It was always soft in the back so I took on restoring the air ride. Even after replacing shocks and compressor I still had nothing. Using your video I was able to troubleshoot and found the relay was bad. They had also pulled the 40 amp fuse. Without your video I probably wouldn't have known which fuse was missing. I finally have a vehicle with a fully functional rear suspension. Thank you again for posting the video. You're a Godsend

[@FarmDad]

I am so glad I was able to help you get your truck sorted! This one has 230k miles and we just started noticing low oil pressure so I'm about to drop the pan and replace the oil pickup o-ring this weekend.

So being an old mechanic and watching you work and your description of the process, you should be an instructor for young people who could use your guidance and skillset ...

[@rgbuckl]

I really appreciate you making this video and being so thorough. I originally saw it after buying a used Avalanche that had that whole system blown out. I did watch it all, but had my sites set on one of those "leveling" kits instead, thinking that would be an upgrade. VERY LONG story short, after 3 months of headaches, back-and-forth with suppliers and shock/strut versions, I came full circle back to this. (Plan D) Just finished the job last night--with your help! There were a few videos out there that were good, but they always cut out the most important part--how it all connects!

[@FarmDad]

Really glad this helped you out! So many people can't troubleshoot the air ride system so they act as if it should be converted, but it's actually a darn good rear suspension, particularly if you tow.

This video is the best video I have seen on the z55…I bought a Denali Yukon that had service ride suspension and I never fixed it thinking it was just too complicated. Now I bought an 09 suburban ltz and was able to diagnose the system using the video…replaced the compressor and shocks. Now the system works. Was able to see the rear left level sensor was bad as well. Before this I went to an INDY GM shop and after mentioning service suspension system…first thing the guy said was “that will be an expensive undertaking “…the. Proceeded to tell me it was best to just do the conversion to regular shocks

I also replaced my problem system with a Suncore system. It lasted about 13months, likely less because I was unware of how often the compressor should actually run. It ran a lot. I reach out to Suncore via email. It took sometime but they eventually got back to me. They said they do not do warranty repairs unless installation was done by a certified mechanic. Luckily, my friend that assisted my installation is such. But they then same back with check this, check that, check this other thing. After about 10 emails and a few months of run around I am finished with them. I agree with Farm Dad dont purchase parts from Suncore. They are not reliable and their parts are junk; per my experience. thanks Farm Dad for the post.

I ALMOST bought the ones that you said are junk. I REALLY appreciate that. My dad has the money for the OEM part, so I think I will go that route too.

Converted to air shocks in the rear. They have air hoses going to the rear hatch to be pressurized. Going to test them soon and leak check the shocks. Some of the original air lines and wiring is still there. Hoping to get the dash lights to turn out. Also didn't see any ride height sensors. Know anything about the front shocks and ride height sensors? I may go traditional or lowered suspension in the future.

The GM pair cost $800 more and had a 35% restocking fee for returns. My original struts from the factory original were a different part #, but the dealership did not have that part number on file and assured me they current one purchased was correct. Arnott are same as OEM GM however there may be different levels of quality. Good luck DIY people

I ran into the same issue with suncore. Their air pump failed after 6 months and they would not respond. I finally gave up and disassembled it. The rubber gasket was garbage and wasn't installed properly causing water to get inside corroding everything. I went with Arnott for the new pump and for their reman shock absorbers. The Arnott air pump is still going strong 9 years later. The Arnott shock absorbers lasted 9 years before the rubber started getting tiny air holes and leaking. The OEM ones only got 5 years before leaking. I'm good with replacing them every 9 years and was happily surprised they lasted that long.

[@FarmDad]

One of those weird car noises that you actually want to hear every time you start it! 😂

[@dennisweber1928]

One clarification may be in order Farm Dad... It is my understanding that the "Air" components you address all throughout your video and text are actually NOT part of Z55 Autoride, but are instead part of the G69 AutoAir Level Control RPO code which is usually on the Denali and Escalade. Air only goes to the rear shocks. The Z55 Autoride suspension is the Magnetic (electric, not "air") components on all 4 front and rear shocks. (Some expert should please correct me if I'm wrong.) This was a very good video. I love your feedback about your horrible Suncore Industries experience too. Good to know!

[@FarmDad]

It's my understanding that z55 is the suspension code, which refers to the autoride suspension where you are correct, computer-controlled shocks all around with air in the back. Z95 refers to the magneride suspension. Thank you for watching.

[@dennisweber1928]

@@FarmDad Excellent, Farm Dad. Just found that Z55 in a 2007-up always includes G69 "level control" which is just the RPO code for the air compressor component bolted to the frame and pumps up the rear air shocks.

[@paison318]

Question: If the jumper from #30 to #87 actually fired up the compressor, with the relay working as you tested, then where would you go? Each shock connector?

[@FarmDad]

Does it come on at startup? If it does, I would check the ride height sensors. If it doesn't, it could be your air ride module. It's best if you can pull suspension codes, which requires an advanced scanner. Sometimes it's worth paying a diagnostic fee at a local shop. Good luck.

No I didn't.

[@joeyschroter4977]

I changed compressor and both rear shocks. And ever since I've had an intermittent traction control stabilitrak light come on when I come to a stop. Checked all connections and cant seem to get rid of it. Also had it diagnosed 3 times and they couldn't eliminate it either

Would you be able to answer a few questions about this gen GM suspension? Looking to buy a yukon/tahoe and the car i’ve been looking at has the service suspension light on.

Feel free to post your specific questions and I will see what I can do.

@@FarmDad Well I’m checking out this one specific car (2007 Tahoe LS) and the guy says there’s a service air suspension light on. I don’t think this car had air suspension but maybe it’s a hybrid between air and regular shocks. Anyways, if the car runs well and the 5.3 looks good and trans shifts well do you think it’s still worth buying? I’m a little hesitant because of the check suspension issue but the seller insists it’s nothing major. I find it hard to believe but wanted to check with you.

@@FarmDad also figured i’d mention it was an auction vehicle that is now being resold. no service history and 146k miles. if there’s anything I should look for when I go take a test drive tomorrow let me know. Thank you!

@@happybub9927 hmm, so much of this depends on how handy you are with cars. I think you are probably right that it's not an air suspension because I think it would need the ltz package to get the autoride shocks. Regardless, there's something wrong and it can be a hassle to troubleshoot without a tech2. Usually, if it's an easy fix, the reseller will fix it before selling it, so I'd be a little wary. In general those are decent trucks but they do have their issues. I can't remember what year AFM started, but trucks with that feature are prone to lifter failure, particularly around that mileage. Just something to research in advance.

@@FarmDad AFM started the exact year of this tahoe (2007). i am also looking at a 2007 Denali with 143k miles which will cost me about 4k more but it has the 6.2. i don’t know which is more reliable, but if i had to guess it’d be the 6.2. with that being said i’m sure it’s also a lot more to replace. i am, however, wondering if it would be possible in the future to swap a 6.2 with a 5.3? if i went the Yukon denali route would this be possible?
