Technical uno sting wiper problems

[shovel2]

My wipers have stopped , have checked all the wiring and the switches but can't find the problem, then they started but didn't last long, any ideas ?

As with the window opener, the switches tend to go into high ohms.
That´s due to the sparks that leave dust on the contacts.
Also check if the motor runs gently when connected directly to a current. These motors also dont last forever.
Plugs tend to corrode. Test the wires and connectors with a strong light-bulb to see if they deliver a proper current.
