99' Elantra evaporator
 

MY AC evaporator went out and the cheapest estimate so far to replace
it is 600.00 with an aftermarket part, Hyundai would not even give me
an estimate until they had the part in hand but did say they run
around 500.00 plus installation but they wouldn't give me exact amount
without ordering the part.
Is 600.00 high for aftermarket installed by Firestone?
