The AC in my blazer has not worked since I bought it. I thought it just may need to be recarged so I went to recharge it and the compressor will come start spinning for about 2 sec and quit then spinn again for 2 sec and quit. It will keep doing this. Does this mean my compressor is bad or does it mean the clutch is bad? Thank You ---

Those aren’t the only two pieces of the puzzle. Two pressure switches regulate the cycles and freon level must be correct , not just adding more. A clogged orifice screen could make pressures act wierd and the residue clogging it could indicate a bad compressor. . . or not. Old seals may have let freon leak out and your refill is incorrect. . . or not. In other words it’s not quite that simple and needs checked by an a/c tech. ---

I guess I’ll take to a shop and see what they have to say. Thank you so much ---

Your Blazer is equipped with a compressor that is a known problem child. Your compressor likes to leak at the joint where the case halves join. Usually you can see a gray discoloration at the case half joint if they are leaking. Rapid cycling is a sign of low charge.
