I bought an 88 formula a month or so ago, so I haven't seen how it reacts to all different kinds of weather yet. I know it used to have a sunroof and the previous owner put a hard top on. Previously I've taken it out on dry days (even with rain the night before) and nothing was wrong.

We had some massive storms in the area the past couple days, and more to come throughout the week. Today I go to take it over to the tire shop for new shoes and I get dripped on as I back out the driveway! I look up and the buttons for the interior dome lights were crying There seemed to be a decent amount of water in there, enough to fill a couple napkins at least. I wasn't able to get all of it out before my appointment. When I started the car it took a bit to get it to crank. I assume the water up near the lights is shorting things out or possibly draining the battery.

Obviously there's a leak somewhere, but where would be the logical choice? Behind the roof line? Windshield? How would I seal it up better than it already is? Want to take care of this before it gets worse or the water rusts the top off.

I had a very similar problem on mine water would show up by my window switches. My problem was that when Safelite put in the new windshield the original installer used the wrong sealer. Since the Fiero windshield is a part of the body structure it does not use the same sealant / adhesive that is used for other cars. They replaced the windshield under their lifetime warranty using the correct sealant. It has not leaked since. If the wrong adhesive was used the windshield will start with a leak up over the rear view mirror. If not corrected you will see cracks start on the outside at the top of the A pillars as stress builds in that area from the body movement.

Thanks for the info. I'll definitely check that out.
