Front wipers malfunction.
Hello everyone
I'm having a problem with the front wipers.
The car is stationary, when I activate the wipers, they work without problem, but as soon as I start the car, the wipers remain blocked.
I take the car to the case, and here are the fault codes that come up:
902A :the component or the cable of the component f58kb (wiper relay on/off)has short-circuit to ground
902B :component or cable of component f58kb (wiper relay on/off)short-circuited to plus
902D:component or cable for component f58ka (wiper speed relay 1/2) short-circuited to ground
903O :component or cable for component f58kf (horn relay) short-circuited to ground
I changed the 2 relays
A Wiper speed relay 1/2
B Wipers ON/STOP
But no change
Can you please help me? Is there a link with the rear Sam? I don't have any fault to identify on the rear Sam.
