Bettery is good but I can start the car and door lock, radio all others not working except light

Hello Al,

Does your dash display a flashing "service soon" indicator?
Have you checked for fault codes?

You have a good battery, your ignition switch is powering up the vehicles dash board and the vehicle will start and operate normally....?

Any lights on the radio display?
Check for 12 volts on the radio power lead...no power? check for 12 volts across the accessory / radio position in the fuse box. No power but fuse is good...wiring issue in the harness.

Power across fused circuit no power to radio check radio's in line fuse...fuse good? ... radio bad or disconnected speaker wires.

Make sure all your vehicles grounding positions are clean and tight.

When you say your door locks don't work are your talking about the switch on the door or the remote fob?

Check your owners manual to check for any radio reset info.

there is another fuse at the back of the radio , will need to remove the radio to replace the fuse

replace IC of car door lock... this is a little black box inside the steering wheel cover

look for another fuse box in or under dash. still sounds like you have a blown fuse. look in owners manual for all fuse box locations,including underhood electrial center. good luck.

Try resetting the electrical system by locking and unlocking the doors with your key in the driver's door 5 times in a row. A service manager at a Volvo dealer showed me this after they did some work on my car and on the way home the sunroof wouldn't close.

I have a 2001 S80 that I have to reset the electrical system like this every time I disconnect the battery. All kinds of stuff stops working...sun roof, door locks, lights, radio, windows, etc. Just reset like described and everything should start working again.

Good luck.

i had a similar problem on my ford probe. i found that the fixed live to the radio had split. it left me with only switched power from the ignition. over time it shorted out and i lost radio, central locking and dash lights. i replaced the fuse in the back of radio and had to have the wiring checked! oddly when it was checked over no other faults were found apart from the split live.i replaced the live feed, reconnected the battery and everything was fine. Dont know if this helps but u never know. Good Luck

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.

Is the engine turning over? When you turn the key to the on position, does it behave normally? IE, do the battery and airbag and other lights come on when you turn the key to on position?

make sure you clean your positive battery terminal. It can be quite corroded in there without any outside signs. Next check ground connections (main ground is under the underhood fuse box...is it rusted down there? If it's none of those, start looking at the ignition switch.
