fuel pump relay full of water! 200 1986

I bet the foam carpet underlayment is saturated. Maybe the floor has already rusted and the water simply runs out the holes.

Somewhere -- maybe around the windshield or around the wiper or around a through-the-firewall harness grommet -- water is sneaking in.

You can probably restore your relay by thoroughly washing its internals with warm soapy water and then rinsing, rinsing, rinsing. And then drying, drying, drying.

And then resolder the relay. Remount it so the lugs point downward (which is the normal orientation).

And also find and fix the leak.

Check your wiper relay for the same problem. It's on the driver's side, extreme left, under a metal plate under the carpet -- about where a tall driver's left foot might rest near the firewall. You can see wiring harnesses disappear behind the metal cover from up under the dash.

Pull the harness up and you'll find one or two relays plugged on the ends. The relays are usually wrapped in plastic foam.

Look under your car for rusty floorboards, maybe even the foam sagging through.
