Hi,

I am new to this forum and any help would be appreciated. There is no such active forums in my country so i am posting here.

The problem-

Today fuse #33, which in my car is labeled as one for lights, just started to blow out for no reason. I haven't upgraded or changed any parts, all the contacts look clean and are not corroded. One thing only, if i change the fuse to a bigger one, then fuse #20 starts blowing out. I think maybe its labeled wrong on the sticker at the back of my glove box, because outside lights are working. Only if its a short in wiring.. but why my lights are still working..

Things that are not working-

1. Dash and speedometer lights

2. number plate lightening and when i check the manual, it says that GEM module shouldn't too, but haven't checked that and i really don't know what it stands for.

BR,

Car is 2007 fiesta mk6

Never change a fuse with one of a higher amperage rating, as doing so risks an electrical fire

try unplugging both number plate lamps at the connectors and fit new fuse of correct amperage (7.5 amp) then see if dash /speedo lights work

actually i did that once, and after doing that it disapeard for 2 weeks, but i could not understand how that fixed anything

its not fixing anything, its isolating the cause, if doing what i said stops the fuse blowing, then theres a fault /high resistance in the number plate lamps/wiring etc.

if it jkeeps blowing then the cause will be in a different part of circuit, process of elimination

Thanks, that was helpful. Will update tomorow if I find the problem!

one question... if the contacts on number lights were abit coroded, that may raise the resistance on the part of the circuit?

thanks for the tip, but i already knew that, that wasnt a good idea

correct

was solved with new number plate light units, and with cleaning the corrosion from wires
