Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.

Expert:  sebastian manrique replied 14 days ago.

Dear customer, if the light is turning on, it is not a problem of fuses or power supply, anyway, it is not necessary to do a check of fuses and relays but the fault you are experiencing is with electric wiring, it is sending the first signal but it does not keep it normally It can be corrosion in the connections because the cables are pitted in certain sections which causes them to be exposed. My recommendation is that you check the state of the electrical wiring and connections.

all conetions in rear side i've been checked and cleaned meybe at fuse box in wire conectors could be a problem
Expert:  sebastian manrique replied 14 days ago.

It's possible dear customer, check the wiring with special attention because from my point of view, it is a wiring failure.

Customer: replied 13 days ago.
thank you for answer.
another question is. what would happen if i amputee the positive wire from middle brake light and took positive wire fom left brake light to the middle brake light?
like i said before side brake lights woks perfectly. is it will be ower power on the wire of the side brake light?
for now i know that my positive wire doesn't work like it should be.
Expert:  sebastian manrique replied 13 days ago.

Dear customer, as your car is 2008, you could try, it seems to me that it should work normally, otherwise the lights will simply work more and you would have to remove an independent cable for the central light.
I am glad that you have found the defect in the wiring.
Kind regards, Sebastian.

sorry but i didn't found the damage. but today i noticed when car ignition is on then the light work for two seconds. but when engine is on if not pressed brake pedal before turned on the light is working. but blinks some times. meybe something with battery?
Expert:  sebastian manrique replied 13 days ago.

It could be a problem charging the battery, but the problem is that it is happening in just one bulb, therefore I still leaning to problems in the wiring.

Customer: replied 11 days ago.

could it be i got in car wrong bulb cluster? or i should hawe a led laps instead bulb.
my car registration number
Expert:  sebastian manrique replied 11 days ago.

Dear customer, maybe the bulb is not correct but I do not know what you have installed but the wiring check includes the fuse box, so it is also likely to be a problem in the connection this happens a lot.

Customer: replied 11 days ago.

im curious meybe previous owner changed all rear boot lid. or the bulbs.
i did clean all conetions at the fuse box but no changes
Expert:  sebastian manrique replied 11 days ago.
