I have a 3.6 2011 durango that has been down going on a month now, I made a post earlier about the a/compressor but that problem is taken care of I'm getting a no crank no start which is how I found the frozen compressor so I had already bought a re-newed starter motor for it got it installed ( which is another headache) and had the battery replaced it was under warranty and tested bad. So I completed circuit test did drop voltage tests on the battery and have zero drop on either cable tested the relay to the best of my ability it ohmed out good, used a jumper wire across the 2 relay terminals and got same results I can hear the bendix clicking but I feel like maybe the motor itself is not good I just had this new battery tested this evening and it's good. So I guess my question is where do I go from here? Do I go ahead and pull the starter motor and bench test that? Oh and I tested the voltage to the starter solenoid as well got 12 volts to it at ignition

 

Does your vehicle have any open recalls? I remember reading about a TIPM issue on that model. May be worth a shot.
