Same exact hose fixed mine. I temp fixed a 3 inch section with heat shrink. Front wheels started pulling. 03 s10 4.3 4x4 automatic, 160k.

You are the best. Thank you so much you saving a lot of money for me. I fix it by myself.

Where does that vacuum line go? So- this video is just "check your vacuum lines" argh... waste of time

you can tell these guys went inside and got on World of Warcraft after this.

I have a beautiful 02' Blazer ZR2 4x4 in 2023. That actuator under the battery is almost always the culprit. Dorman just came out with a new Heavy Duty, much thicker rubber actuator that cost $70 at O'Reilly's.. However, if you have the old actuator from O'Reilly's. They'll swap it free of charge because it has a lifetime warranty. I don't have that nipple inside the driver's side wall or fender like on this one.

Thank you so much sir. 5 dollars in hose gave me my 4x4 back.

Great video my guy! Life saver

my 2005 s10 blazer 2 door4x4 had a burnt vac line going to the transfer vac switch

MAN, I scoured the internet looking for a 4x4 fix on my 05 Blazer and this fixed it! You're amazing!

Easy way to tell that is a vacuum problem is that your heater will not work correctly because your heater hose is connected to the same line and it also takes vacuum to actuate the HVAC flaps

Did you shove it on that bolt?? I'm not seeing a nipple

We have a Sonoma GMC 4+4 someone had the actuator onthe top side of the battery I moved it out of the way to put jumper cables on and now it wontgo in anygear

The transfer case switches is on top of the transfer case with 3 vacuum lines my switch failed and I had fluid throughout my entire vacuum system had to replace everything

Great job really like how you guys were very detailed about the process.

Nice vid.

They sell kits to switch the vacuum actuator to a locking cable that sell for over $100. I ordered a locking PTO cable from eBay for $12. and fabricated the end bracket from stuff I had in the garage. The other thing this gives you is the possibility to have 2wd low range as well.

Dude thanks for the vid, much appreciated

'97 Blazer...no lights on at all and fuses good...replaced both actuators, cable, and dash indicator switch..still no 4-wheel drive...any ideas?

Good video i lol when you sprayed your self 😂☠️

Really good vid. Thanks

What is the part actually called, the swishy thing?

Thanks!

Love my ZR2 !! Oil is changed faithfully every 3000. Has 187000 and my every day driver.

Thanks for taking the time to try and help others w this problem. I believe this is fairly common w these blazers.

Thx 4 the video my son has a 2001 Chevy Blazer LT 4x4 and had the same problem. The 4x4 doesn't work. There is a part that has two small 5/32" vacuum lines the top vacuum nipple is missing the vacuum line it had a rubber cap on it located in the middle top of engine (by firewall/windshield just so u get idea of where it is). Do you think you can make a video of that rubber hose line so I can see where that line goes to please zoom in on the.line so I can see where it gets attached to along the way to the actuator under the battery like you said. Thx a million if you can do this. 👏🚘👍👍

The lens glare at 4:36 is positioned amazingly.

Reverse don’t work wat do I do

Nice Video👍 I picked up an 03 Zr2 for $500 Canadian yesterday. Looking forward to tinkering with it. Thanks for the insite, it was veey helpful.

I don't own a blazer but I've always wanted one so I'm watching for fun lol

This video more like a comedy!!

you need to work on your video making skills. no you did show a useful piece of information that nobody else showed in their videos. which could save a lot of time

After 9 videos. It was your video to show me the vacuum line under the driver fender. Thank you. Just bought a 99 Blazer yesterday and 4x4 didnt work. NOW IT DOES

Thank you for taking the time to share this fix, That was cool

I’ve watched a lot of videos on this matter and came across your video by accident, went out immediately to my truck and sure as shit that vacuum line you pointed out was rotted. Replaced the line and everything works great. Thank you for the video a $3.00 fix.

If you are ever in Yakima, Wa, hit me up. I would like to buy you a beer.

Mine just flashes and u can hear the computer click

Douud you're a life saver I've been chasing this issue for the last 22 weeks. I also noticed and could hear the vacum line hanging on the driver side of my Jimmy Tought it was for the ABS or something like that from what I could find from diagram. Thank you so much for the video!!

Hey brother nice ZR2 and great info upload. FYI you have a issue somewhere with starting it. Cap and rotor are toast more than likely. Ck air filter to. Im a Zr2 guy.

i really need someone to help me,its about my chevy vortec v6 2000 ,its about the ecm ,i wish to know how the ECM works to the injector, cause i find a + in the harness same as the negatif - at the same time, so i wish someone to understand me, and give me some advices just to repair my car. i hope you will give a good answer soon , thanks for your support.....

i couldn't use a bow in this game even if i get the developers to add a micro-transaction to making it easier to operate.

I got a 2002 no lights flashing on dash at all where do I start looking first thanks for any help .oh also all fuses okay and relays okay

wow the vacum hose on mine was off just like yours was thanks much!!

My ZR2 4x4 lost 4wd yesterday. The little hose came lose. I reconnected it and it worked! Thanks!

Great job..these things "Shit-10"mpg gas station blazers...designed by GeeManiacs (with as many problems possible for a p.o.s. truck, because these Rockefeller corporations hate american auto workers) their toyota brand is not too bad though, at killing american jobs. So, it's great to see someone who can find these Gremlin Maker's problems under the hood. GM...Designed to fail america every time, period.

Thanks brotha

t hanks fixed mine

That is a very nice looking ZR2 Blazer black Fender Flares red paint. And yes there are a lot of ways the four-wheel-drive could act up it is kind of a ridiculous system all the vacuum lines on these trucks rot away eventually they turn to Ash they all do it. I've looked at many of these trucks in the salvage yards.

My blazer does the same thing on startup, and takes a little while to turn over. Do you know what the cause of that could possibly be?

I know the 4 button is alittle diffrent from the 3 button ..however if your at the point in this video and still having issues you want to look at the cord (rusted from moving or the front diff where the cord is going into ...vacuum switch maybe stuck (rust) This area is famous for rust and water and seals failing and a diff burning out...check your diff fluid While your there ..I have my diff out and i'm putting new seals everything else is in good shape
