    I went out there today and checked the vacume lines, pulled one off one at a time and sucked or blowed into them, the one going to the small sylinoid with 3 lines going to it one of them had a hole in it, so i just cut it and put a peace in it. and pulled the tccm fuse for 10 mins . and 4x4 works fine. it had a miss .. the miss is gone . runs good...before it would be hard to start... now it starts right up thanks to rufftuffcrea... i would have never checked the lines...jerry t

Chevy blazer problems

Hi Cecily,
There are several parts to a blazer 4x4.
First is the transfer case,When you push the button for four wheel, can you hear you it locking up,by pushing the buttons from 4x2 to 4x4 ?
If you here a slight clunking sounds its working. Next Blazers now have to lock in the front wheels. This is done by a vacuum assist. There is a vacuum line from the engine that runs over and under the battery.If it looks like it is attached at the engine, The next part is harder. You need to remove the battery to expose the servo valve that the vacuum is suppose to work.You can start the engine before taking the battery out, it will stay running. Pull the vacuum off the servo to see if its moving.if not replace it. if it is moving, there is a small relay mounted on the fire wall in the center of the fire wall, replace it.

2000 blazer 4 wheel drive problem

It's most likely the "four wheel drive actuator" This is located on the front differential housing. It's cylindrical shaped and has a large hex (about
1-1/4") and two wires coming out of it. Usually they short out and blow the fuse but, I've also seen where they just quit working and sometimes they just get slow to work. The "actuator" has a heating element in it and it warms up, some sort gas, causing it to expand thus engaging the front wheels. In cold weather it may take a minute or so for it to engage, so put in four wheel drive and wait for a bit and see what happens.

Four wheel drive not working on 1994 chevy blazer

I had a 90 S10 4X4 so I hope I can help. The front axle on this truck is locked by cable. The housing for this cable is found behind/around the battery. I found the vacume hose was falling off the plug and was not locking the front axle. When the truck is put into 4wheel, you can check the locking of the front axle here. Now if everything is working there, you might want to check the the transfur case is working. If the truck has electric it will have a electric motor on the side of the transfur case. If you have a manual shift on the transfur case then you would have to make sure that the rods are moving and locking into place. Hope this gives you an idea as to where to start looking.

Your blazer is equipped with a shift on the fly four wheel drive. That means that at speeds less than fifteen miles per hour you can shift into or out of four wheel drive by simply pushing the four wheel high button. If you wish to shift into four wheel low. Stop, put the transmission into park or neutral, and push the four wheel low button. Same procedure for shifting back out. Never shift into or out of four wheel low while moving. And be careful in four wheel low. At full throttle your still barely moving, you don't want to blow your engine up!
