[@ddischiave]

This is the very best explanation of the C3 vacuum system I have ever seen and I love the diagrams and your testing techniques as well. You obviously understand how the C3 systems work. I have a '71 Coupe where I followed your instructions and it made the job super easy. It makes me wonder why GM just didn't use small electric motors, like they did for the C2's and C4's. It would have simplied the assembly at the factory and it seems that it would have been overall less expensive. Thank you for taking the time to share your knowledge.

[@ProblemSolverGarage]

No problem

I was trying to get help on You Tube and BANG! There you were! Great tutorial! Do you have one showing how to properly remove the gauge cluster? I need help with the two bolts found underneath the radio. I'm told those have to be remove too. Thanks again.

[@patricksteen9413]

Your video is absolutely perfect. Lots of technical details, easy-to-follow troubleshooting, and great part recommendations. I have all the assembly manuals and seen a multitude of videos, but none of them demonstrated the process (with a project car) like your video series on the C3. I wish your video was out a decade ago, but extremely glad to see it now. Thank you and God bless you.

[@michaelgurgone1611]

After leaving my first comment last week about “not even owning a corvette” I now have my cousins 1969 big block corvette sitting in my garage. The car has been sitting in her garage for 9 years under a dusty cover and she asked me to get it running again, so your video series is a God send to me. I already pre oiled the motor and did the same procedure you do preparing the engine for its first start up. Now I am going through the vacuum system trying to get the wiper door to work…but it looks like someone was previously tinkering around with the vacuum actuator for the wiper door and the moment I tried to unscrew the actuator like you did in your video the whole lever inner arm fell off inside the plastic housing box! I found the small nut and washer laying at the bottom of the plastic housing. The problem is there is no access to get in to the plastic housing to re attach the inner actuator arm to the wiper door linkage inside that plastic housing box!! The only way to gain access is to use a small 2 inch hole saw and make a access hole on top the plastic wiper door actuator housing so I can re attach the hex arm to the actuator arm. Any other ideas? I definitely don’t want to take apart the whole wiper door linkage and spring to fix this problem. Seems like making a access hole on top of the plastic actuator housing is the most practical way, I can always plug the hole when I’m finished! Again, thank you so much for this incredible video series… it’s the gold standard for anyone who repairs or owns C 3 corvettes. Your definitely the best on KZbin or anywhere else!

[@ProblemSolverGarage]

Thanks and good luck with your project, maybe the access hole isn’t a bad idea, sounds like the simplest way

[@MATTAC3R]

I never comment on videos, but, I’ve also never been so surprised to see such a fantastic video series…. I’ve had the vacuum hose kit in my garage for a year and have been intimidated to get started. No longer the case. Will be using your videos as reference for the restoration.

I really appreciate this video and look forward to watching more of yours. I just got my dads '69 that they bought new this Christmas. He passed away last year so I don't have him to help me with the car that he built. He was mid project when he stopped working on it when I was about 14ish. It has just a few odds and ends to finish up and seeing how simple this era of car is via your great videos has and will help me understand this era of tech! I didn't even know how to adjust the temp or where the air blows when I drove it home from their house! Anyway, Thank you I like your style!

[@ChiefyChieferton]

Loving these videos. I would have struggled much more with my C3 without them. For testing if the light actuators work, I used a hand vacuum pump. You can get them as part of a brake fluid bleed kit, or just on their own. I basically just pumped a vacuum by hand to test the light popping mechanism. This could help if you can't start the car while doing these repairs.

[@ProblemSolverGarage]

Thanks for the feedback and good idea, thanks for watching

Great videos, both the electrical and this vacuum one. I have watched them both several times but I cannot for the life of me figure out why my wiper door fails to open when switching on the wipers. I have checked for leaks, the wiper door solenoid, actuators and relays, also the electrical, all seems ok, but I am at a loss. I am definitely missing something. Oh welllll.

[@ProblemSolverGarage]

Sorry that you can't figure it out, once you do it will seems simple I'm sure. Maybe your heat controls are leaking? You can temporary disconnect them

[@user-ot7cf3zf4h]

Thanks for your reply, much appreciated. I will check them out if any line disconnected as these were also replaced last year with the rest of the vacuum lines. Will let you know. Thanks again. Frank Toronto@@ProblemSolverGarage

Something put both of them out of commission ; \...any ideas Tom or should I just get the vacuum hose kit and get to work?

[@jeffthompson3814]

I've got a 1969 427, 390 hp that has a wiper cowl issue. When the car turns over, the cowl comes up. I know it's vacuum related but I can't nail it down. Last year I replaced the windshield wiper door actuator, wiper door actuator vacuum relay, and the wiper door safety valve. Just this week I replaced the check valve. I believe the safety valve and wiper door actuator are functioning correctly. Do you know how the Actuator vacuum relay is supposed to hold pressure? Many Thanks. PS... I enjoy your videos, they have been super helpful.

Great video. I am currently troubleshooting my vacuum system and I have noticed that my check valve is not working, so I tried to just bypass it for now and use a hand vacuum pump to pump up vacuum directly to the vacuum canister, but it is not building up any vacuum. Should a hand vacuum pump be able to do this you think? Or is the vacuum canister simply too big for a hand vacuum pump?

[@adynroselli8560]

Would you recommend a Detroit speed electric conversion for the wiper door and hideaway headlights? I have no problems with my vacuum actuators I just don’t know if it’s worth it to convert them
