Save all those desiccant packets from pill bottles and chuck them in your trunk?

Baby diapers are also very moisture absorbing maybe pull the absorbent pack out of several set them strategically in the trunk see if the swell up?

This is such a strange problem to me because all the moisture in the air where I live falls to the ground as snow. I swear Alberta is dryer than a desert in winter.

It might be tricky to figure out a good way to accomplish it but if absolutly no leaks is certain. Insulation is one way. Some form of forced ventalation might be engineered in as well.

First though make sure what you are experiencing is what it is. This should be easy by just checking other cars in your vicinity. This effect is somewhat unknown on the east coast of Canada to the best of my knowlege. Although the principal moisture showing on the underside of the trunk lid is more typical of condensation as you mention than leakage I would suspect.

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).

As for the trunk, some kind of vent is your best bet. My quarters were rusted out and the trunk never had a condensation problem (living in the humid NE)
