1998 Dodge 2500 24v diesel. drove to store and back got back in about 15 minutes later and it will not turn over not even a click. Power windows and heater fan will not work either but everything else does lights, gauges,power locks radio etc, checked all the fuses and swapped some relays under the hood around still no luck. Where do I need to look now?

 

Pop the plastic covers off your steering column (around where the ignition switch is) and have a look at the ignition switch connector, sometimes a wire will break there or get pulled out of the connector.

 

Or look again for a fuse in engine compartment module.

 

Clean battery cable connections, check cable ends, check grounds, possible starter contacts, ignition switch, fuses: along those lines....

 

in your engine compartment fuse box there is a ignition run fuse,there is also an ignition run/ASC fuse ,make sure that the IGNITION RUN FUSE is good , if memory serves me right it is a 40 or a 50 AMP maxi fuse
