Dealership says I have a leak in my evaporator behind the dash. They will fix for $1300. Car has 150,000 miles and runs great but need AC. It gets hot here in VA. Talked to a mechanic about Stop Leak. He recommended not using it. Said - It may work but there is no guarantee and if it does not work no one will work on your AC after you have put Stop Leak in. Car is only worth a couple thousand dollars and I hate to spend $1300 to fix it.

 

Are you pretty good with a wrench?
I posted some directions on how to replace it yourself.
