Volvo Repair: volvo s70 a/c, blow dries, dye test

Question
my 2000 S70 (75,000 miles) has an A/C leak.  Dye test shows leak in evaporator.  Unit holds pressure enough to be charged but leaks down to poor performance in 10 days or so heavy use.  Rather than a $1000+ replacement, is there a good leak sealer I can try without damaging system?my 2000 S70 (75,000 miles) has an A/C leak.  Dye test shows leak in evaporator.  Unit holds pressure enough to be charged but leaks down to poor performance in 10 days or so heavy use.  Rather than a $1000+ replacement, is there a good leak sealer I can try without damaging system?

Answer
Hello Stuart,  The repairs you need are not uncommon,at those miles we started seeing it develope.If you are to sell the car,don't do anything.This a command decision,"How much do I love My Volvo?",Once she is repaired,I suggest having volvo's "Afterblow system" installed.It takes about an hour to put in and cost about $70.00,well worth it,heres why.The system turns on the blower motor on ,50 min.after you turn off the engine.It will run for 5 min. at high fan. This esentially blow dries the evapoator so moisture won't settle and corrode.It won't happen all the time,only if the a/c has been On for at least 5min.I have one on my 2K S-70 and 60K miles it went on 2001. thank you and goo hunting.As for the sealer find out via 800#s what manufacture liabilities are if any.I've not used them.Only"solder seal"in the radiator if the federalies are chaseing me. thank you and good hunting!
