#96 of 115 2004 Blazer 4WD Not Engaging with Button
Dec 15, 2010 (7:49 am)
I have a 2004 Chevy Blazer with push button 4WD. Last winter in the NE we had a ton of snow and I used the 4WD a lot.
Once winter was over I attempted to push the button to engage 2WD and it would not go. My buddy who has a 2500 HD Silverado told me how to do it and it worked. The problem is that now when I push the 4WD button it will not engage the 4WD.
I have two small children and with winter upon us in the NE I need to get this repaired. A co-worker had a Blazer and it had a similar problem that he said cost about $150 to fix.
Does anyone have an idea of what it could be and could an average auto guy do it himself?
Any feedback would be greatly appreciated.

#99 of 115 Chevy Blazer 4 WD Issue Resolved
Jan 04, 2011 (4:13 am)
I was experiencing the same issue as many Blazer/Jimmy owners (push button 4WD not engaging). I thought it might be an actuator.
I took it to a mechanic and lo and behold it the diagnostic test revealed a bolt needed to be removed and replaced.
Now it is working fine and a very inexpensive repair.

I just had the same exact issue. The vacuum line that runs behind the engine had fell against the exhaust manifold and melted a hole in it. There was a palstic union there and i disconnected it and shortened the vacuum line 3 inches where it was melted and reconnected it, there was plenty of extra hose on mine. Problem solved.
The vacuum line runs down the passanger side by the transmission dipstick tube and transmission lines, i didnt need to trace it any further. Cut the vacuum line start the car with 4x4 engaged and check for vacuum and reconnect it with a union.

#105 of 115 1995 Jimmy question
Jan 24, 2011 (9:38 pm)
I was wondering what the black bulb thing on the driver's side mounted to the hood is. It has a black tube that comes out of it and then breaks off into two other tubes. One of the hoses has a hole in it. Wondering what it is for.
