Title: Number plate fuse keeps blowing...
Post by: 05omegav6 on 10 February 2014, 20:12:47
Fuse 26 blows every 2-3 weeks :-\

Starting to get irksome...

MID still works, not sure if washer jets do or not (as the bottle is split, so empty as soon as filled
 they do seem to be when bottle is refilled, bulbs replaced a couple of months ago (which solved nothing) :-\

Wonder if either bump in July has pinched a wire at the headlight washer pump, or the pump trying to draw screen wash through when bottle is empty loads the fuse enough to pop it...

If anything, the pump load is reduced when the washer bottle is empty.
Empty or full, the only way it would realistically pop the fuse is if the pump is seized (or partial seized).

So running the pump dry might ultimately have caused its partial demise, thereby cuasing it to draw more current and overload the circuit :-\

F26 doesn't power the headlamp washer pump, only the timer relay that switches the motor. Motor is on F39.

From what I can see, F26 powers the number plate lights, the illumination behind the heater vent controls and precious little else.

Shouldn't keep blowing then... Heater vent bulbs are second to useless, but wiring is intact, tailgate wiring appears ok, unless a wire is chaffing inside the tailgate :-\ all other tailgate functions work as advertised...

Yep, is the wiring chafing where it passes into the tailgate?

Might also be worth trying it with the headlamp washer relay removed. Maybe that's gone faulty?
