Compressor was making a rattling/beating noise. I replaced it, along with the receiver dryer. The inlet side of the dryer had visible metal shavings, so I think I better replace the condenser. What about the expansion valve on the evaporator? The evaporator? Anything else? I had a shop remove the refrigerant, so it's empty now. I just need to put the parts back and then take it back to get charged.

hopefully the shavings stopped at the drier. Take the line off going to the expansion vale. see if any shavings are there. if none there
good to go. if present replace the expansion valve.

Thanks. I did only see shavings on the inlet side of the dryer, nothing visible on the outlet side. Do I just pull the line at the firewall and look? Or should I remove the expansion valve itself and look?

The route is compressor to condenser, to dryer, to expansion valve (with the evaporator), to evaporator, back to compressor. The expansion valve is part of the evaporator assembly under the glovebox.

Should I use compressed air to blow out the lines from compressor to condenser, condenser to dryer, and dryer to firewall (assuming I see no more shavings beyond that point)?

Just pull the line at the firewall. No need to blow anything out at this stage. If the inlet to the expansion valve is clean (firewall) Then the
drier did its job and stopped the shavings. lets hope

Bro, if you have endless money for a '99 Civic then just replace the entire HVAC. If this is a DIY, avoid the evap/expansion valve, and condenser unless the fins are ruined. Charge it, see if it holds. Get back to us.

Condenser comes right after compressor and costs $47. I will replace it.

No visible shavings at firewall. Using compressed air I blew out the line from dryer to evaparator. Grey oil but no shavings. New compressor, dryer and condenser, new o rings wherever I pulled a line. Oil into those 3 components. I guess now I take to the shop for vacuum and charge. I'm tempted to buy a manifold and vacuum pump, but not sure I would use it again.

Gauge manifolds and vacuum pumps can often be borrowed from auto parts stores. If not, gauge manifolds are cheap, and vacuum pumps are cheaper than paying someone to do it for you.
