I have a friends fermec 860 at my place and it just turned on the lights and rear wiper and the two speed pump stays in low speed, no leds light on the side control switch panel. I have good power and ground to the fuse panel and everything comes on when I turn on the key, I found corrosion in the k4 connector and cleaned it out but still same thing, I have a manual but it's hard to follow and I see a lot of diods in the system, anyone have any ideas, thanks
