There was another thread on this a month or so ago but it tapered off inconclusive. I seem to recall that the OP on that one wasn't in the PNW.

There are several usual answers for moisture in the trunk, but the part that baffles me is the condensate effect on the trunklid.

That suggests that you either have standing water in the trunk, which apparently you haven't, or somehow moisture is being drawn into the trunk from outside and rising to the trunklid. I associate condensate with either pooled water reacting to temperature, or moist air movement.

Uber-weird and I can't offer any explanation... unless it's a generalized problem of all the seals being old and allowing moist air to enter, through some vacuum effect when the car is moving?

I had a serious but generalized moisture problem in the trunk last fall and winter (everything in the trunk was damp but no pooled water), but only slight condensate on the trunklid. All I did was to carefully clean around the trunk seal this summer and I left the trunk open in direct sun a couple of very hot days and 'massaged' the seal in one spot where it had deformed slightly. The sun seemed to help straighten it out.

Anyway no problems so far this fall.

The area where I live has the opposite problem to where Scott speaks about... we have very high humidity levels most of the year (and I live in a particularly bad spot that doesn't improve matters).
