SOURCE: 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.

1995 blazer 4wheel drive not always working


on the transfer case area there should be a relay to tell it to go in to 4x4. now once you put a blazer in 4x4 and no longer need the 4x4 En-gauged you will need to put the blazer in revers and back up 10 to 15 feet to get it out of 4x4 before driving.
