Allright I guess I have no choice but to take the car back to the dealer once again ! It just came back from the shop for A/C repair with a bill of 1400 last week !

At this point I need to have the 6 vacuum actuators replaced since the air flow is not working properly. The dealer quoted me 9 hours of labor and parts on top of it.
I'd like to know your opinion whether or not that sounds right ?
more over while the shop is doing this, would it be wise for me to ask them to have the evaporator replaced as well .. ?
if so how much more labor will that be and roughly how much am i looking at for the evaporator and the 6 vacuum switches ?
thanks a bunch.
it's for the 87 260E.
