Hello guys. So i need help. My car's Central locking suddenly stopped working, also the turn lights and back lights, none of them aint working. I tried some fixes, I checked the fuses and everything was good, also checked the key fob damage and still no success. i chamged the battery(i had bad battery) and still the same, and lastly i also changed the fuse box(comfort block), which is located in the engine bay and still nothing. So i was thinking if the problem is in the wiring or somewhere else

Any help would be appreciated, Thanks!

 

Questions:
1. Have you lost FM radio reception?
2. Does the IR fob unlock the door when you point the fob at it?
3. Is fuse #8 in the trunk blown?

If yes, your alarm siren has crapped out and blown the fuse. The antenna amp is tied to the same circuit. Disconnect (or replace) the siren behind the RF inner fender liner, and replace the fuse.

As you know, the fob uses both radio AND IR to lock/unlock. Losing the antenna amp kills the radio function, but the direct line of sight IR should still work.
