I have a 2000 300 4X4 AC. I am having major issues getting it started. Everytime I push the button to start all I get is a single click, never tries to turn over. Lights work and new battery. Any ideas!!!!!

 

Check battery connections and ground connection. Clean carefully.

 

Same problem on 2001 500 auto. check relay in right rear wheel well. (it has a clear plastic cover that slides up when you push a clip). lift the cover and carefull jump the two large leads with a pair of needle nose pliers (rubber handled). With the key on I betcha it'll lite. That'll give you a start
