Not really an RV question, but related to my class a. Last spring after MH was basically sitting all winter (5 months) and started it up to leave, wipers started working and would not shut off (did not turn on the wipers). Had to disconnect wire to motor to get them to stop (it wasn't raining). Since then, plugged wire back in (WD-40 SPRAYED), wipers will only work on low speed and only when I turn them on. No high speed and no delayed operation. Is there separate fuse for delayed operation? Any ideas?
