Power socket fail­ure

Car Mechanics (UK) - - Tales From The Workshop -

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!
