I've done the dye thing twice, once two years ago and again last month. This time my mechanic found the dye leak in the evaporator. Is this a common problem with all older Volvo's or just 850? Has Volvo improved this weakness in new models? I beleive its a leak in the evaporator and have no air after refilling the system just last month. So what should I do? The job to fix it is suppose to evolve pulling the steering wheel, air bag and front dash to get at the evaporator to replace it or about 1200-1300 dollars. If I keep the car another two years thats $50 a month for air (even in the winter), but I live in the south so it nice to be cool. The car is is very good shape and has been well mantained; it runs good for 123,000 miles. Should I sell it since it's only worth $5,000 or so; or fix it. Is there a different alternative to repairing this thing. Do all cars have the evaporators under the dash where you can get at them. I quess Air Conditioning is something new to the Swedes. They certainly didn't over-engineer this item. Any help or ideas here?
