if your a/c doesnt work, i wouldnt even bother tryin to mess with it yourself unless you have a really good knowledge of how it works.....the mod that fixed his a/c actually had a no brainer since it was empty....but if you guys just start adding r-12/134a to your systems, you run the danger of over-charging your systems, which means what? well, super high head pressures in your a/c compressor, which means what? BOOM!!!!!! then you blow the side of the compressors out, cuz most honda compressors are sanden rotary type, which means a huge mess of pag or ester oil all over your engine compartment, then you need to spend lots and lots of money, replacing your condensers, cuz its impossible to flush metal chunks out of them, flushing the rest of your system, possibly having to replace your evaporators, expansion valves, driers, and all that fun stuff.......if you guys still wanna do this yourself, let me know, ill get you as much info on the specs of the systems as possible.....(i work for an auto air distribution center) good luck.....:thumbup:
