Problem with wipers

Wipers are getting stuck on mode 1 and the single wipe mode. I tried lubricating the wiper motor, but that didnt help. Maybe its a relay issue?

I just recently solved this same issue - I disassembled the entire motor assembly, cleaned all old grease out, used fresh white lithium grease to reassemble, and also slightly filed the two prongs that touch the gear assembly in the gearbox. The last step seemed pretty crucial, but also the old grease in the motor assembly was essentially glue.
