AFTER PUTTING THE CAR UP ON 4 JACKS AND PLAYING AROUND A BIT i FOUND OUT THE 4 WHEEL DRIVE IS OUT. WHEN I PUT IT IN 4 WHEEL DRIVE I HEAR THE CLICK IN THE TRANSFER CASE BUT NOTHING ENGAGES. THE VIBRATION I WAS GETTING SEEMED TO IMPROVE AFTER TURNING THE 4 WHEEL ON/OFF SEVERAL TIMES. SO I'M GUESSING SOMETHINGS BUSTED AND THE VIBRATION IS COMING FROM WHAT EVER IS BROKE WITHIN THE 4 WHEEL. ANY HELP WITH THE NEXT THING TO CHECK IS APPRECIATED, I'M COMMITTED TO GETTING THIS 2001 BLAZER FIXED AND IF NEED BE I GOT A PARTS BLAZER BEHIND MY GARAGE.

THANK YOU

MIKE

 

Mike,
First thing...turn off the caps lock, makes reading difficult.

Second, check the vacuum lines under the hood, left side between windshield and wheel. Usually most of these need to be replaced. Follow the line that goes over the engine and under the battery tray (remove battery) to the actuator that engages the front axle. Common for this line to be rotted and/or the cable this actuator pulls to be frozen or broken.

Spend 30 minutes using the Search function and read about the 4wd system here on the Forum and you will be able to fix this.

Good luck.

 

Caps lock off! And thanks a lot!! I will post the results..
