IS IT A COMPUTER BOX PROBLEM AND WHAT IS THE SOLUTION?

2004 Subaru Forester • 125,000 miles

After cleaning the car, we noted the car engine would not start, door won"t lock, power windows not working and lights wont turn on. As we tried to turn on the engine, no "clicking sound " was heard thus we ruled out a battery problem? Thanks. Tina

Your logic is all messed up. Nothing works, so you ruled out the battery? The battery and cable connections would be the first thing to suspect. I'm not sure how you figure the Engine Computer would cause the power locks and windows to not work. That computer is not a suspect for those systems.

Did you "wash the car" or wash the engine? If you washed the engine, you may have disturbed an electrical connection that was about to cause trouble on its own. Clean and tighten the battery cables. Also, follow the smaller positive battery cable to where it connects to the under-hood fuse box. Shine up that terminal with sandpaper and be sure it's tight. Follow the smaller negative cable to where it bolts to the body and be sure it's tight.
