I need to know where the fuses are for the radio and power locks

You need to input the radio security code, when battery power is lost the radio goes into theft lock.

Sounds like the wire you used for power was oon the circut for all those other things, or if you pulled the fuse box down to hook radio up through the fuse box, you may have grounded out some wires, or knocked them loose. Use a test light or voltmeter and make sure you have power at the fuse box for wiper,dashlight, trunk release, door lock fuses.

Your Car's lights, power locks, and radio are sometimes on the same fuse...check your manual to locate the fuse panel and inspect for blown fuses...

I don't know about that car but you may want to look into a control module. one that controls the various system you're having trouble with

my radio and power options wouldnt work and it said security. My boy friend disconnected the battery cables and quickly rubbed the positive and negative ends together which rebooted the computor. I do not know if its good for it or not but it definately worked my power options are back.

There is most likely a fault in the system and it will have to be reapired by certified tech

Under the hood on the fender well,Big black fuse box.Fuses are marked on the cover.

Same problem with an '03 Golf--remote entry, power windows, and interior lights stopped working. This was easily fixed by replacing fuse #14, (10 amp), located in the driver's side fuse block.
