Driver's door won't lock (maybe because my media system?)

[Sagi313]

Hello,
i own a seat ibiza 2012 1.4l.
2 weeks ago i installed an android multimedia system by myself in the car,
and i think that at about the same time, a problem started in my door lock.

when i lock the car (remote or key) all the doors get locked,
execpt for the driver's door. it makes a sound when it tries to lock lock it self,
but it won't work. also, thier is a flashing red light on the door.

i think it has something to do with the electric system. because it started
at about the same time after i installed the media system and because thier is
also something wierd about the system. when i ignite the car, the multimedia system
turns on without loading, like it has a power source connected to it. is it normal?

anyway, i could use your help to find out the problem because i want to fix
it by myself (the garage wanted 400$ to replace the car lock. without even
knowing if this is really the problem).

thank you!

doesnt seem likely to me that they are related.

Do you have any clue of how can i fix the door lock?

And also, what is causing the multimedia system to turn on with out loading? Power supply?

Usually it needs to replace the module that it is inside the door.

I had to replace the 4 of them by now.

But my car is from 2008 and had a previous version of the door lock.

you can get them relatibly cheap on ebay.

be aware that if your car is LHD uses different locks than RHD so be carefull what you buy.

I can give you the part number later if you want... just give more details about your car.

no, door lock is much more likely than anything else.

is your car from UK or other part of the world (LHD vs RHD)

supposing you are in israel, is it LHD?!
