Hi, I'm new so I hope this is the right place for this post. I have a 2010 9-3 aero and after driving home from the car wash the car won't start. I tested the battery and it's fine, the windows work, the radio sometimes works. When I try to start it, it just makes a clicking sound. The fuses appear to be fine. Could there be a short somewhere? I also had them wash the underbody as well if that helps. Any suggestions would be appreciated. Thanks!

 

try removing the distributor cap and drying it out with some electrical cleaner. Any moisture in there will inhibit the current sent through the plug wires.
