So my 2000 durango locks have been going crazy. They randomly lock and unlock while driving and sometimes while parked. I found a TSB about door lock switches (in the keyswitch) but all of those appear to be working (when I turn the key the dome lights come on) So I was thinking it may be the CTM but so far there aren't any other signs that the CTM is bad. Right now I can lock the doors thru the switches but not unlock anything but the drivers door. Which seems right given the separate relay for the drivers door. Any one have any other test I can run before I start hunting down a CTM or new key switches?
