had a squeek on my 98 that was somewhat unique (as far as i can tell)
but you might check this if it is a very high pitched squeek:

Just to the inside of both A pillers, site down behind the dash and
see if there is a thin piece of plastic about 3 inches wide portruding
from the dash and barely touching the glass. It looks like it might
be used to align parts in assembly. In any case, the plastic was just
touching the glass and the plastic would resonate with a very high
pitched sound. I cut it out using a razer blade held with a long
medical clamp (don't know the name of those devices).

Plastic was on both sides. This removed the main squeek in my car
(although 40K miles later I do have some rattles behind the glove
box now and one behind the radio).

The build date on my 98 is January 1997 (yes 97) and is on the door
(in case you want to check). If you have the plastic parts they are
obvious and easy to see.
