Condensation on inside of the windows

[kindlethespirit]

This spring I've noticed when it rains for a while, I end up having condesation build up on the inside of the windows. When I start the car and turn the a/c on the condensation goes away after a short time. I'm also having a musty smell until the condensation goes away.

This is the first year that this has been an issue. Are there drains somewhere to check to see if they're blocked? I'm also going to treat the top to repel water.

This doesn't happen while washing the car. It seems that the top has to be wet for a while. I've also done a search and not found that there are too many problems with this.

Any other ideas?

Here is a list of the drains:

Where the water leaks can be very important. The worst being a leak that pools water under the drivers seat and floods the electronic components located on the floor board.

Thank you. I'll check on those tonight and also check to see if there are damp carpets. I'm hoping not because as soon as the a/c comes on the condensation clears right up and no musty smell is present and no smell before or after the condensation.

I cleaned my rear drains with a shop vac. I just put the hose over the drain hole and waited until I didn't hear stuff bouncing up the hose. Seemed to work great, just be careful not to scratch the paint with the plastic vacuum hose.

Have you ever sealed the top fabric? I've had it happen once or twice when it's been wet and humid for several days. 'vert tops aren't impermeable like a steel top, they do "breathe" a bit.
