I had the same issue with a clicking noise on the passenger side of the car, located somewhere under the dash. I pulled the dash apart and there is a motor located underneath the dash next to the vent that operates the flap on the floor to switch between pulling air from outside and circulating the air inside the cabin. That motor is stripped out and it's just freely spinning. It will require ALOT of digging in order to get to it, so I just left it.
One or both of you're drive axle bearings is dry
Mine was the egr valve fixed the shutting off
If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
Maybe bad CV joints?
If there is a clicking noise get it to a mechanic you engine is blown and may be saved. Most likely you'll need a new one because a lifter is broken and it would be cheaper.
If just clicking and not starting, most likely a dead battery.
close but ur an idiot blazers dont have pinions. they have gear boxes.
it is the door alarm
The kids in the back.
Brakes
Bad wheel bearing
if its coming as you turn it would be lack of lubricante in the cv joint or it could be the ball joint, as far as engine wise it could be your valves
