a/c problem
 

My 2000 Sonata stopped blowing cold air. I was told the evaporator core has a leak.
One Hyundai dealer tech. told me I only need to replace the evaporator...while others are
telling me to replace the drier, and expansion valve as well....don't want to spend the extra money
but , I want to fix it right to possibly avoid another costly repair down the road. The car has about
88k on it... need to keep it for another couple of years before getting in to a newer model.
