Before testing the headlight switch, check for a defective general electronics module (GEM) and 15A FUSE 32 in the central junction box (CJB). These components could be the source of exterior lighting problems.

Transmission can suddenly 'grab' when it/you changes gear. An automatic transmission can be sluggish to change gear if the fluid is dirty and needs changing. A worn/slipping clutch on a manual transmission causes the engine to rev high before the car picks up speed.

From your description it sounds as though there's a misfire or rough running with the engine which causes the jerking, not the transmission unit.

There's many things that can cause the symptoms you describe - the MAF sensor .. fuel starvation .. O2 sensor ..

Get a good mobile mechanic to look at your car - or take it to a workshop. I don't think it's your transmission at fault.

This is off an 03 ST hatch but pretty sure it's in the same location.
Good luck

Start with cleaning the throttle body, idle air control motor, and MAF sensor. After that, tune up.

most likely a problem starter motor or starter relay
take it to an accredited auto electrician and have it checked out

Yes they do unless the car is been sitting there for a long time then the motor would be stuck making it very hard or imposible to turn the crackshaft

Check the owner's manual for all fuse and relay locations, but there is no such relay for the headlights, the dimmer switch is likely the problem. Have it diagnosed electrically.

Assuming you Focus does not have DRL, setting the light switch to low beam energizes the low beam relay in the battery junction box, sending power through 10A FUSE 16 (L) and FUSE 17 (R) to the headlamp low beam elements

When does this happen?

2003 Ford Focus | Answered on Sep 13, 2016

If you brake lights stay on and the cruise control doesn't work then I would be looking at the brake light switch at the top of the brake pedal as if there is power passing through it then it cuts out the cruise control. The same as if you put your foot on the brake cuts out the cruise control. The hatch button will be another problem like a fuse or broken cable or failed latch solenoid. As to the rear middle brake light try checking the bulb first.

There isn't one ! This vehicle relies on serial data communication . The PCM sends an message on the data bus to the microprocessor inside the instrument cluster . The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key ON engine OFF, and stall conditions.
Charging System Warning Indicator
The instrument cluster receives the charging system status from the PCM over the SCP or CAN communication network. The PCM controls the charging system and the charging system warning indicator. The PCM is therefore responsible for turning the lamp off once the system is running and illuminating it under fault conditions (including stall conditions).
How to Diagnose Controller Area Network CAN Your best bet would be to take your vehicle to a qualified repair shop .
