2004 Chevy Blazer Compressor bypass pulley

No, I don't see a bypass made for that engine. Yes, it can be driven to the shop for evacuate and recharge but I hope you realize what your getting into. The compressor is no big deal but you mentioned evaporator. If attempt to change one of those, you will really regret that. You also need to know some technique when working on A/C. You need to be able to seal things with no leaks and be able to recognize something that will be a problem.

OK, it's not the evaporator your referring to. That's in the dash. Your concerned about the condenser and rightfully so.

It doesn't sound like a bearing problem. It sounds like the compressor seized up which means it sent metal particles all through the system, mainly the condenser. Sometimes they can be flushed but some cannot. That's where the experience comes in. You have to determine if your condenser is a "bypass" type which cannot be flushed and has to be replaced. If it's a "serpentine" type, then it can be flushed but you need the right chemical and correct tools to do that.

You also have to determine what caused the original compressor failure because it will simply do it again if not resolved. These are the reasons that A/C repair is really not a DIY type repair.

You have to physically look at the sides of the condenser. You look at the tubes and see if they are all fed from a central pipe/manifold than rund vertically which would make it a bypass type and non-flushable. If you see one continuous tube then serpentines back and forth in the condenser, then you can usually flush that type.

Don't go by the manual pictures. You have to see what is actually in your truck.

I usually pass on the filters. They are just another place for a problem to occur. Just either replace or flush completely the condenser and replace the orifice tube for sure.
