Remedy
In case of customer complaint perform the following checks prior
washer pump replacement:
1. Check if the antifreezing concentrate is OK, respectively that
the washer fluid/system is not frozen.
If the concentrate is insufficient/the washer fluid is frozen,
inform the customer about the correct mixture and/or refer to
the owner manual.
2. If the washer fluid is frozen, defrost the washer system and
fill-up washer system with washer fluid in correct mixture.
3. Check the function of the pump and nozzles of the washer
system if necessary replace the washer system fuse.
Note: A frozen pump will cause the fuse to blow through again.
