A/C blowing hot air
My mom has a 92 Legend whose A/C stopped blowing out cold air. From what I can see, there hasn't been any fluid leaking. I thought it would be a good idea to drain the freeon and fill the system with those sealant foam products they sell at AutoZone, but I can't find the low pressure service fitting. The Haynes manual shows it and a refrigerant line at the back of the engine that isn't on my mom's car at all! Can anyone provide help, preferrably with pictures, and advice if I am going about this the wrong way. Thanks for the help.
