wiper motor replaced-still want work on 2006 Dodge Ram 2500

Someone said replace module-very expensive-any other alterative? If not, where is the best place on-line for this type of part.

The best alternative is to have it diagnosed properly so you don't replace any other un-needed parts.

I have the same problem, but if I "jiggle" the switch the wipers will work but only "When they want" so that tells me that the problem is in the switch.
