  • Remove the serpentine belt and unbolt the compressor from it's mounts and tilt it up so you can get to the front easier.
  • Use the clutch removal tool to pull off the clutch.
  • Remove the large snap ring in front of the pulley.
  • Spray some WD40 in the hub area and remove the pulley from the compressor. It's best to use the universal puller.
  • If you don't have the puller bolt the compressor back down to it's mount and carefully pry the pulley away from the compressor. Be careful and don't stress the gas lines. The pulley bearing is pressed onto the aluminum casting of the compressor body so you are not prying against the compressor shaft. The bearing can be hard to remove because the steel bearing in contact with the aluminum frame will cause a dissimilar metal weld.
  • Clean off all the surfaces and threads using a wire brush and / or some sand paper. Note: The white circular object is the magnetic coil that activates the A/C.
  • Place the new hub on the frame and tap into place with a piece of wood or use the special puller tool which will also press the new hub into the frame.
  • Press the hub in until the groove is exposed enough to install the large snap ring.
  • Install the large snap ring. Make sure it is seated all the way around.
  • Install the clutch assembly taking care to position the shaft key in the compressor slot. Use the special installer tool to press the clutch into place. Leave between .020 and .030 air gap between the hub and the clutch.

Good luck and keep me posted, Be glad to answer any questions you may have and if you need help replacing the coil also, (clutch core)

My 2001 Chevy Blazer keeps popping the fuse for the heater. What could be causing that?

Hello! One of three reasons that fuse is blowing...#1...Defective A/C compressor clutch relay...#2 ...Defective A/C compressor clutch...and #3...There is a diode across the compressor clutch that may be shorted...Lets narrow it down...If you do not have a meter just disconnect the compressor and see if a fuse will hold...If it does the problem is the clutch or diode...If you do you have a digital multimeter and a wee bit of experience using it...disconnect the plug from the A/C compressor...Wire colors are Dark Green and Black...Read across the compressor clutch (where the connector was seated)...You should read 4 to 5 ohms...on the X1 scale...If you read zero ohms the clutch is bad...I believe the diode is in the plug end Read from the Dark Green wire to bare metal chassis ground...You should read open...send results...Saailer

Chevy 2004 blazer ac stoped working abruptly and stops the engine if you turn on the ac could you just replace the clutch if that is what is defective? instead of the whole compressor and all the other...

I mworking on my blazer AC unit now . You have a problem with the compressor clutch or the compresser Its likely the clutch its supposed to cycle about 8 times per minute . So it goes on then off 8 times per munite this is normal . However if the clutch dosen't spin then the belt will drag on the clutch pulley this will stall the engine until the belt wares out but this will damage every part that the belt rides on . The water pump the alternator powersteering pump and belt tenisinor not to mention the belt .It sounds like your clutch is seized try not to run it until you can figure out why the clutch isn't spining

1996 chevy blazer what is the easiest way to change intake manifold gasket

there really isnt. you have to disconnect everything bolted to it and lift it off. I would leave everything bolted to it and just disconnect hoses and wires. Everything you unbolt from it you will have o reseal the bolts when you put them back in which means cleaning or replacing each one.

1996 Chevy Tahoe air conditioning not blowing cold air

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.

My 1996 chevy blazer a/c compressor doesn't engage

check fuse then relay, if both ok disconnect snap in wiring harness at the top of the accumulator tank and use a jumper wire . plug it into the end of wire harness turn a/c on to max if pump kicks on ,then its not the pump but switch that is screwed into the accumulator tank. ran into the same problem with my 97 blazer definetly a cheaper fix than pump also make sure a/c is discharger first before removing switch a/c is a pressurized system so you dont get hurt or worse frostbite

Disarm airbag in chevy blazer

You need to disconnect the battery from the vehicle, and wait at least 1 minute to disable the airbag system. Your airbag system is designed to hold energy for 1 minute after a power failure, and will deploy if you do not wait 1 minute.
