'02 WRX - A/C troubleshooting

I'm mostly unfamiliar with A/C systems, ZZ, but fellow board poster Steve J. keeps various manuals online. Just happens to have an '02 WRX/Impreza manual, from which I would suggest taking a look at the Wiring, and maybe some other section, for troublshooting ideas.

its most likely a overcharge or undercharge of the coolant is the pressure is not right the compressor will shut off get your pressure checked and add some 134a

Yep, quite likely the refrigerant has leaked out enogh to trigger the low pressure cut-out. I dunno if it's important but the wife's'03 Outback had both suction and discharge hoses replaced (barely under warranty) dur to leakage. Perhaps Subaru had a bad supply of them?

One additional question. Recently, fuel rails were replaced by Subaru service due to a leak (smell of raw fuel). Is it necessary to drain refrigerant when replacing fuel rails? I suspect that service guys didn't refill refrigerant after this procedure or they managed to screw something up during the procedure. By a chance, I didn't have to turn on A/C until recently and that's why I didn't notice A/C malfunction before....

Often they can 'lay aside' a compressor with lines attached - though that is not without risk. I just don't know. perhaps someone here is a tech and knows the procedure. It is very possible they just forgot to re-charge the system if it was opened.

Thanks for spending your time and posting advice 'bigjim' but I was asking more for a technical advice, not a generic consumer advisory....
