Hi everyone!
Interesting fault last week
2018 ford transit
Fault wipers only working on full speed no washer
Found fault code B1131 Wiper motor module
Did some looking into and there is two wiper motors controlled by a LIN signal
Found a TSB related to washer fluid coming up through the washer pump connector into the the drivers side motor connector which then controls the NS
Removed plug and did find some moisture and signs of fluid in the connector.
Although I did expect it to not work at all, or is this like the blower motor fan resistors where there do work full speed if there is a fault?
