    What do I need to make a proper R134a AC conversion on my 91TT

    As the tittle says is anyone kind enough to tell me (and help build a data base here) exactly everything I need to do a proper R134a conversion ?

    So far, last year I had the compressor and the drier replaced (I think they have put new seals) and even if I use my AC only maybe 15-20 times last year, at spring time, I had no more gas in it, leaked by a seal, I went to refil the system but after that the AC doesn't work anymore : when I start the AC, I now got the 'red dot' instead of the 'ninja blue star' after a few minutes on the screen.

    Thanks

    Eric

    I would just stick with the r12 system. any reason your not just fixing the system but instead just replacing it?

    I'm in for information. A friend of mine did the conversion on his Grand National by swapping all the parts to R-134a parts. I guess the difference in the particle size between r12 and r134a means that r12 parts using r134a will never make the air as cold as a proper r134a system.

    Yeah I've heard that as well. Also I think that R12 will leak out of a r134a system.
