Hi guys . ı got a 1995 model chevy blazer 4.3 4wd. I am so happy to meet you .ı got some problems. My 4wd dıdınt work so well .So ı changed the 4wd swıtch. When ı push the 4 hi button nothıng ıs happennıng .when ı push the 4 low the electronıc motor ıs workıng ı hear the voıce ..but my vakum actuator doesnt work completely .ı have to push vakum myself .ı and ı notıced that my vakum actuator is dıfferent .ıts not lıke the other blazer actuators .ın a normal blazer the vakum actuator under the battery. Mine is not. Its at the top of the compressor so what can ı do for my 4wd ??


Thıs ıs actuator.
Its dıfferent.
Aır work compony ...never heard about ıt .

 

That's a modified "home made" unit in my opinion. I have never seen one like that on any vehicle. I would search a scrap yard for a stock one, and replace it. Would be my first step.

and you have a nice looking blazer. Love the side steps, they look custom as well.

 

Thanks )) ıts lookıng good but not workıng good

 

Pretty sweet truck.

Where are you from, Yankee_35?

 

I am from turkey

 

Welcome to the forum.

It looks like the unit has been damaged. Try to figure out how it is supposed to work, The spring to me seems as it should act against that spacer.
The solution may be that simple.

 

Thanks. Yes the sprıng ıs broken and ı need to change ıt wıth an orıgınal vakum actuator. But also ı need to solve some elektronıc problems .

 

There is also a thread on how to make it a manual actuator for less then 30$ in parts... maybe so a search for it and see if that could be an option for you.

 

Dear Donl how can ı Do it manual ?? Is ıt bad for the car ??

 

Not really. It simply makes you use it manually, so you could simply forget to activate the front axle in 4x4. Not sure what could happen when riding it in 4LO. The torque will be directed all to the rear wheels.

I would try and see if you can engage it properly with the actual rigging. It that is working a repari with a new spring may be an easy fix.
Else you could look for the OEM parts at a scrapyard and bring it back to stock, but I guess there has been a reason why somebody fixed it that way.
Might have been he wasn't able to find the correct parts. Have a look at rockauto.com, they may even have all the stuff.
