Peugeot 107 wiper failure

I had a similar problem with my old Renault Clio. The wipers just quit. The problem was a dodgy connection in the wiring harness that goes to the wiper motor. Have you checked the plugs and wiring around the motor and the wiper switch itself?

Thanks for the tip! Where exactly should I be looking for these connections? I'm not very experienced with car electrics, so any specific locations or things to look for would be really helpful.

On my Clio, the main connector was right on the wiper motor itself, under the plastic cowl at the base of the windshield. Also, check the connector behind the wiper switch on the steering column. Honestly, if you're not comfortable with electrics, it might be best to take it to a workshop. It could save you a lot of hassle.

Took it to a local garage. It was indeed a faulty connector, as you suggested! They cleaned it and secured it properly. Total cost was 95€. Thanks so much for pointing me in the right direction!
