Twingo Lighting Fault

I had something similar on my Twingo. Check the fuse box first; it's a common area for electrical gremlins. Are the dashboard lights also acting up?

Thanks! Where exactly is the fuse box located? And by 'acting up' with the dashboard lights, do you mean flickering or something else?

Yes, flickering. It was a pain. The fuse box is usually under the dashboard on the driver's side. If the dashboard lights are doing the same thing, it really does sound like a dodgy connection. Honestly, I just took mine to a workshop.

Appreciate the advice. Turns out you were right about the dodgy connection. Workshop confirmed it was a defective cable connection on the light switch. Cost me 95€ to repair. Thanks!
