After reading several threads I'm completely and utterly confused. Skreem? Siren? Tear apart dash? Replace siren under cowl?

So far there seems to be two camps.

1. Get siren, replace under cowl, be happy.

2. Take to dealer, order skreem, have dealer F it up, replace dashboard poorly, have squeaking piece of junk car.

Which is it? Please help.

Thanks.
