It is illegal to produce R-12 but not to purchase it. In some states you need to be Certified to purchase (I am) however it is all over craigslist and ebay. I looked on Ebay.es, I don't read in Spanish so I am having a hard time finding a can but I do see recharge kits (don't know if its real R12 or junk). In your situation you are probably going to end up at an A/C repair shop. BUT, if you can diagnose the problem, half the battle is won and you won't have to worry about a local shop pulling the wool over your eyes. To recharge your system (top off) you will need... A. A charging hose for R12 B. A can of R12 You can buy the charging hose on ebay.com and have it shipped to spain, but I highly doubt you can buy a can of R12 on ebay.com and have it shipped to Spain. Here is what I suspect based on the information you gave me. The compressor front shaft seal is faulty... the Ester oil in the A/C system leaked through the seal along with some R12, caught the compressor clutch and that slung Oil all over your hood. Of course this is all speculation based on the info you gave me. If you can top off the A/C system with a can of R12 and dye, in theory the system will engage... the vents will blow cold air and the compressor will push out some more R12, oil and dye. You will see the dye on the hood and will be able to diagnose it as a bad compressor. Then you will need to take it to a shop and have the compressor replaced and the system recharged. Please do these tests before assuming its the compressor and taking it to a shop to have it replaced. It may very well be something else... I feel like its the compressor, but the only way to be sure is to Test it. P.S. This is very unsafe but i do it. If you jump a lead to the a/c compressor and force it to engage while the engine is running technically with what is left it should blow cool air... but keep in mind this is unsafe because if the system has a blockage you are building pressure and could damage the system further, or hurt yourself. Also, oil probably has been leaking out in which case you could damage the compressor further (lack of lubrication). If you are going to try this do it for just a very short time.... 1-2 mins. Good luck DG |
