If an A/C compressor is seized then before it seized it will send debris through the entire system(Evaporator,Condensor,Reciver/dryer & H block(or sometimes called an Expantion valve) & these components can't be cleaned out. All the A/C lines can be cleaned out with Brake Clean & compressed air. If the system is not cleaned out compleatly then there is a good chance the Expantion valve will get plugged. Trust me. I have seen this many time. Another BIG thing is after you put everything back together you MUST pull a vacume on the system (30in) for atleast 30min to boil out all the moisture. This is very important so the system will work properly. Also NEVER reuse any seal or O ring on any conection because it will most likely leak later on down the road.
All cars & trucks by Federal law started using R134A in 1994. R12 is very hard to find & VERY Expensive.
Repairing A/C is usually not cheep even for me because the parts are expensive but the BIG cost is labor because replacing an Evap involves removing the entire dash on many cars. I have no experince doing A/C repair on VW's & wan't to keep it that way because every time I get stuck working on a VW it always turns into a nightmare. There's always some sort of special tool needed to do a repair on thoes Germin cars. No wonder they lost the WOR!!! I can definetly say replacing Evaps on "most" Honda's & Toyota's involves just removing the glove box & 2 of 3 halves of the heater box asembly. I gota say thoes Jap's got some good ideas sometimes but then again they also lost the WOR. Goes to show ya not to mess with the Good Ol USA.
