Problems when it rains. HELP PLEASE!!!
I have a 98 GS400 and love it but lately it's been giving me problems when it rains. After driving it in the rain, the electrical system goes haywire. The power windows stop working, the AC doesn't work, power locks don't work, sometimes I can't put the car into reverse or drive and the last time it stalled whenever I put it into drive. This has been happening the past year and it always happens after a big rain storm. After everything drys out, the car goes back to normal. Anyone have ideas on what's going on?

is ur fuse boxes completely sealed? interior ones or the ones under ur kick panels? anyway for water to get into the fuse boxes under the hood and the ones by the door? is the rubber cover on ur driverside door completely in? watertight? check those 1st i would assume since its a problem of the rain its prolly because of stuff exposed to water

This isn't going to be easy to resolve. Does the car work alright if it has just been sitting in rain storm? Or does it begin to mess up after being driven in rain storm? If it's after driving I would guess it's from road spray and probably some connection under the hood getting wet from missing body components. If does it after just sitting there I would venture to guess it's a leak into an interior component. I know this doesn't help much but it might limit your search area.

Make sure the compartment to your ecu is secured and closed. Also check the rubber gasket on it. For so many components to go haywire I would bet on something going on with the main ECU

Kick panel area is dry. I took it apart and it seemed dry.
Main ECU was all dry as well.

Happens after driving.
On a couple of occasions, the starter would crank by itself. It was like it was posssessed.

A loose connection under the hood could also be part of the problem. This combination when combined with the force of the water spray hitting the loose connection COULD be shorting things out. When you get the issue resolved let us know what it was.
