Have you had vehicle check for DTC'S diagnostic trouble codes . Check fuse's an relays , find wiring diagrams to see what controls these systems ?
Radio/Battery fuse , fuse G 10 amp located in the right instrument panel fuse box . Do you know where this ?
Fuse Block - Right IP - On the right side of the instrument panel
An there is one on the other end of the instrument panel ,driver side .
Fuse Block - Left IP- On the left side of the instrument panel The fuel an temp . gauges not working is probably the step motors inside instrument cluster . GM had problem with this 03 to 06 .
How to repair GM Instrument Cluster Speedometer Gauge Stepper
Daytime Running Lamps (DRL)
The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the daytime running lights (DRL) or the headlights. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. With the headlight switch in the OFF position, the headlights will either be turned ON or OFF, after an approximate 30 second delay depending on whether daylight or low light conditions are sensed. The HTR A/C IGN fuse in the underhood junction block supplies ignition positive voltage to the daytime running lamp (DRL) relay coil circuit. The DRL relay switch contacts are connected to the low beam circuit. When the headlamp switch is placed in the OFF position, the BCM will either turn on or off the daytime running lamps, depending on whether daylight or low light conditions are sensed. The BCM energizes the DRL relay, closing the switch contacts and grounding the low beam circuit. Ground is provided at G101. The DRL illuminate the low beam headlights at a reduced intensity. The DRL will operate when the ignition switch is in the ON position, the gear selector is not in the PARK position and the parking brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.
DRL operation in Manual Transmission equipped vehicles will occur when the ignition switch is in the ON position, and the parking brake is released. - check fuse's an relay first.
Door Lock System Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch
?€¢
Front Passenger door lock switch
?€¢
Body Control Module (BCM)
?€¢
Relays: Driver Door Unlock--if equipped, Door Unlock, and Door Lock
?€¢
Door Lock fuse 15A

Ignition switch is a solid culprit. the contacts get worn out or even "stretched " due to "Forced" turning of the key. You know the part where you try to turn the key past the stop point.

A common problem on the 2003 focus are the electrics, i had a problem recently where the displays where not functioning, i took off the panel, checked the iso connector and before putting it back in i gave it a quick spray with wd40 and it al seemed to work, been in contact with the garage and for a new unit with callibration you are looking about £140 or so with labour and parts
SOURCE: Driver and Passenger auto door locks are inop.
Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.
I had a similar problem with a 2001 Saturn. We checked every fuse and they were all fine. We finally did a 'reset' on the car's computer by disconnecting the battery and reconnecting it a few minutes later. Everything was back to normal after that.
