Haha i made the mistake of buying one of those once at newark autojumble. Plugged it into my hilux and it worked for exactly the amount of time to get a drink lukewarm before it burned the socket out.
For anyone not knowing, getting all the bits off round the dash to replace said socket on a k plate hilux was a full mornings work....
Needless to say the element went in the bin.
LOL, I changed the heater matrix in one of them , I was close to tears . Then there is resetting the cam belt light on MK 5s , takes longer than changing the belt, full dashboard dismantle job . I only re set my light , as I had half taken the car apart as the bonnet pull stopped working .
