I am working on a 2010 challenger RT. The wipers don't work in intermittent or slower speeds only full speed with no park feature. I have discovered the two relays under the hood are 4 pin the instruction under the fuse cover states 5 pins only. I am thinking these 4 pin relays are the source of my problem, but i am having trouble locating a source for these relays. Any body have a source or thoughts on this problem?

 

while troubleshooting wipers i found two relays under hood that control wiper on-off & slow-fast, these relays are supposed to be 5 pin relays. Some shade tree had replaced the OEM relays with 4 pin.
once I installed the proper relays everything worked YEA111111111111111
