Rear Near Side Light

[koro]

Hi,

I would be totally lost without this forum, I keep looking to see if I can give an answer to someone else`s problem. Except it is me asking the question...

 

My rear near side light, keeps blowing, fuse as well. Replacing these items lasts about 20-30 miles then same again. Cleaned up the earth on the bodywork I have tried to follow the wiring as far as possible but cant find anything amiss. Damm frusrtrating... Want a cheap fix, how would I go about routing a new wire back to the fusebox? i.e where to I connect both ends of wire. Also why do the rear lights both work off seperate fuse`s, could I get away with looping across from the other working rear light?

 

Thanks everyone for looking...

Hi , Fuse 56 VW Sharan 1.9tdi Aug 2000, W reg, newer shape at the time...

no,no,no,no,noooooo.

Dont ever link sided lights. They are sided incase one develops a fault,so at least one is working.

Is it blowing the front side light as well ??

Do you have trailer electrics wired up??

It sounds like you have a short somewhere. What you need is lots of patience,and to start stripping the loom out and following the wires back. Its a long drawn out affair......

Things to look for before hand,is the dash lights going out,glove box,has someone fitted a stereo and cut the wires.

Just a couple of things to check before delving in to some loom stripping..

Hi, I was getting peeved off with it all, hence the idea of linking the rear side lights together, ruddy lights....

 

All other lights work fine, no trailer lights wired up have followed the lighting loom as far as i can... though from what you are saying could the short come from somewhere else on the electrics and not necessary the rear lights wires?

 

If that is the case would re running another wire to the rear light be a waste of time?

 

Cheers

I agree with Mk2sport, don't bridge between sides.

Fuse 56 should be for RH side tail/parking lights!!!

Do the parking lights work as they should? ie indicator on when ign key removed?

If the fronts are working even when fuse has blown then there is a serious problem. (i know I know no s**t sherlock)

Earth points for all lamps may need cleaning/checking for corrosion.

Relay may be a probable cause, i think its on the main relay panel, 3rd row down, far left.

Running another cable will eliminate cause if problem is with that feed but problem seems to be (imo) within fuse box (relay) or possibly indicator/light switch.

Are the number plate lamps on the same fuse ?

 

I'm thinking tailgate wiring !

[MadBaz]

License plate should be fuse 26, 3amp, it is a possibility but any feed/short when light switch is off would be apparent.

Just one obvious possibility, are the contacts in the holder clean and under tension when bulb fitted?

Guys, an update.....

 

When I said earlier that the front side light was working, that was incorect, when the fuse blows front near side and rear near side light goes out. The mistake happened as it was peeing down with rain, and got the Mrs out to check the lights, I of course did the difficult bit of turning the switch ^_^

 

Well as it stopped raining I checked again myself....

 

Definately fuse 56, 5 amp. When replaced, after about 30 miles it blows, though on the last occasion last night the bulb stayed intact. I took the bulb out replaced the fuse and after about 80 miles the fuse is still ok. I dont know if that says something as to where the problem lies I dont know, what I thought I might do is put a blown bulb in and see if the fuse stays intact..

 

When stationary the lights and everything else works correctly..

 

The bulb does feel nice and tight whwn fitted..

 

I really do appreciate you guys spending time with my problem...

Is it a stop/tail light bulb (dual filament) that is blowing? If so then check it is the right way round. If not, check and make sure that it is not supposed to be a stop/tail bulb as a single filament will sometimes work until you press the brake pedal when it can then blow.
