Power socket failure
With the increased use of sat-navs, dashcams and phone chargers, we are being asked more frequently to look at failed power sockets. The in-vehicle power socket is really no more than an adapted cigarette lighter and it’s surprising that none of the big manufacturers have developed a purpose-built DC outlet in the vehicle. Because of the way the power outlet is constructed, we continually find that a fuse has blown either because the adapter has been badly applied into the socket or because a coin has dropped down into the recess accidentally.
This 2006 VW Touareg had a blown fuse. After replacing it, the rear socket was now working, but the front one wasn’t. Only when peering down into it did we discover that the socket was full of biscuit crumbs – or something resembling biscuit crumbs. After cleaning it out, power was restored.
With such a mess in the base of the power socket, it’s no wonder the phone charger wouldn’t work!
