Is the radiator fan turning on?

No neither fan is running.

The best way to approach this is to use the Chrysler DRB3 scanner to access the Engine Computer which controls the radiator fan relay. That will give you the option to turn it on to see if it works.
Without the scanner you are somewhat limited to "throwing random parts" at it, which we really hate doing. In this case, however, that relay is an electronic computer module, and we all know how extremely unreliable computers are in cars. The module sits about half way down on the driver's side of the radiator. It must be bolted solidly to the sheet metal, otherwise it can get hot enough to burn your hand. It's a fairly high-failure item and a good suspect when the fan doesn't run.
Sorry for taking so long to reply. The site stopped working on my regular computer. Just want you to know I'm not ignoring you.
