I would check the wiring to see if there is power going to the motor. The wiring may not be providing power to the motor. Check the relay to see if power is going to the wiring (pin 30 and 87). Pin 30 is usually power from the battery and pin 87 is the wire that goes to the accessory for power. Pin 85 and 86 are the wires that trip the relay. Depending on the wiring of the switch, the relay could be negative or positive switched.

The next thing would to check the switch to make sure that the relay is being tripped by the switch with someone listening for a clicking sound from the relay.

I would also confirm that all the fuses are good cause most manufacturers now double and triple fuse their circuits. There may be a main fuse for the whole car rated at 100-125A in the engine compartment fuse box. The next fuse would be a group fuse at various rating for like the instrument panel lights, radio, and BCM. The third fuse would be for each individual item in the passenger compartment fuse panel. So basically I would verify that all the fuses are good and not blown or missing cause you forgot that you pulled one to replace one that was blown for temporary purposes.

Ultimately, the problem sounds to be electrical.
 
You need to check if you have power getting to the wiper motor or the electrical connection to it. If no power here, assuming you switch wipers on to test it, trace the wires back to see if the wires are at fault.
You may have to trace all the way back to the main power block at the fuse box.
 
It sounds to me like a possible fusible link problem...If you do not know where these are, try going to any parts store and they can help you locate them.
 
I am sort of a back yard mechanic but this one has stumped me good.

My truck is a 2002 Dodge Diesel 2500 4X4 and the windshield wipers quit about a month ago, they wont do anything and I cant figure it out, so far I have;
checked the fuse, swapped out the relay, bought a new motor-still didnt work, took it back, bought the wiper switch that goes on the column- still dont work, too that back!!!
I am at my wits end, Please Help!!!

any questions I will watch and repost if necessary.
Thanks
I have already checked and swapped out the fuses and the relays with other fuses and relays that I know worked.
