I did this successfully on my last truck (Chevy). Get a flush kit that has a canister to connect to your air compressor and specific flush slovent. Disconnect the lines and flush out the lines and evaporator. You really need to replace the condenser. These things are parallel flow and there is no real way to flush them properly. You'll unclog a couple of channels but since they are parallel some will stay clogged as the flush just takes the path of least resistance through a couple open ones and bypasses some of the clogged ones. It is highly unlikey that you will get them all clean so wil have reduced performance and then almost for sure some crap will come loose later and clog the expansion device and you will be tearing it all apart again.
Replace the dryer/accumulator. Oh, this seems to be part of the condenser. Never heard of that before. Very bizarre. Needs to be replaced as it is almost for sure full of metal shavings and other junk. Not sure what expansion device Toyota uses but if the cheap orifice tube, replace it. Replace the o-rings... get a Toyota specifc set of o-rings.
This website has a lot of info on the subject as well as DIY flush kits and solvent.
Here are their Tacoma 2.7 parts:
Here is the flush equipment. I used the one at the bottom (Mastercool canister):
