[Supras] Air conditioner problem

[D P]

James, I've been having AC woes with my 92T as well.  Although I can't help 
you with your problem, I can however sympathize and let you know what mine 
is.  My ac died about 2 years ago and I never bothered to fix it.  Now, I've 
been asking the list questions and weighing my options.  I agree with Harley 
about the dealers.  I'm surprised that the dealer would tell you they don't 
have a manual for such an old car.
I think you're getting screwed by them saying "it must be leaking under the 
dash".  That's not a sure fix.  They should know for SURE if there's a leak 
in the system by doing a vacuum check.  I don't know how that's done but I 
imaging that they can apply vacuum and check for a leak.
I've decided to skip the dealer on my 92T and have a local mechanic (that i 
trust) do a conversion to r134a.  I'm sure I have a leak somewhere in the 
system because I checked the high pressure valve and there's no pressure in 
there.
My advise for you is to go the conversion way.
Good luck and please let me know how it turns out.  I'll let you know how 
mine turns out.
