Title states it all, when it is rainy outside or has been raining the car won't even turn over. Just one click and nothing like it has a dead battery or something, if it is dry out the car behaves normally. Any Ideas?

 

Bad battery...car won't start because of cold cranking amps. Rain=cooler weather=cold cranking amps.

Just a guess.

Get a test done on the battery at auto parts store.

 

Or the starter is drunk

 

It could be, the battery is almost two years old and hasn't spent that much time in a running vehicle. I'll see what it does when the weather gets cooler out, it probably still wont be a daily even then.

I'll keep my Landshark further away lol.

 

lol.

Try jumping the starter solenoid to the battery positive with the key on and see if it starts. Ignition switch might not like the humidity.

 

and/or the relay itself.
