FORD FOCUS 1.8 tdci DRIVERS WINDOW STOP WORKING ELECTRONICALLY HOW DO I TAKE DOOR PANEL OFF TO GET INTO WINDOW MOTOR MECHANISM

First, use electric-safe penetrating lubricant to lubricate the window switch to see if corrosion has caused the switch to stop making contact.
If that doesn't work, remove the door panel and see if the window motor is getting voltage when the switch is activated. If the window motor is getting voltage when the switch is activated, check to see if the window regulator mechanism has jammed or seized. If the regulator mechanism appears ok, replace the motor.
If the window motor is not getting voltage when the switch is actuated, replace the switch.

Not enough oil pressure to open the injectors. Check pick up tube

There was an issue with the steering in that 04-11 focus... let me see if I can find the problems they've had for you.

Ford Focus fuel pipe leak (2004-2011 cars)
Cars built between July 2004 and February 2005 could have had problems with their fuel return pipes leaking. The pipes were made from material that degraded over time, allowing fuel to seep out.
Ford Focus wiper motor problem (2004-2011 cars)
On early second-generation cars built between April 2003 and March 2005, there were issues reported with the wiper motor. Water could enter the motor through the arm spindle, and if it contained salt, could short-circuit it and cause the motor to overheat. This could lead to trim melting around the motor.

Ford Focus engine failure problem (2004-2011 1.6 TDCi cars)
1.6 TDCi Focus models built between February and June 2004 might have problems with their engines, causing them to cut out. Misaligned oil feeds between the cylinder heads and camshaft bearings reduced oil flow, causing premature wearing of the camshaft bearings and engine seizure.
Ford Focus brake pedal problems (2004-2011 cars)
Cars built between November 2005 and December 2006 could have developed problems with their brake pedals. In particularly cold weather, the pedal could become stiff, as the non-return valve in the pump began to stick.
Ford Focus roll-over protection problems (2004-2011 CC cars)
On some Ford Focus CC models it was found that there were issues with the roll-over protection system. Securing bolts holding the system in place were either loose or not fully tight. Therefore the protection would not be fully effective. Ford should have fixed this for free, so make sure the work has been carried out.
Ford Focus cooling fan problems (2004-2011 1.6 TDCi estate car)
On some Focus 1.6 TDCi estates built between July 2004 and December 2006 there were problems with the cooling fans. Where roads are particularly salty, corrosion could easily occur, reaching as far as the control module. In extreme cases this could cause it to overheat, which could lead to fire.
Ford Focus rear hub bolt problems (2004-2011 cars)
On some Ford Focus models built between February and April 2007 there were problems with the rear hub bolts. They could come loose because they weren't made to the correct design specification.
Ford Focus power steering problems (2004-2011 cars)
Ford Focus models built between April and May 2008 could have had problems with their power steering. Some of the hoses fitted were not to the required specification. The hoses could degrade and allow hydraulic fluid to seep out, which could either cause the power steering to fail or, in more extreme cases, cause fire when the fluid became hot.
Ford Focus risk of fire problem (2004-2011 cars)
Hatchback and estate 1.6 TDCi Ford Focus models, manual and automatic, built between January 2006 and January 2007 may have a risk of fire unless they've had their cooling fans checked. Salty roads could lead to corrosion, overheating and fire if not sorted.
Ford Focus water leaks (2004-2011 cars)
On second-generation cars, some owners have reported water leaking into the cabin. Check any sunroof or window seals before you buy. Also look for damp carpet inside, because it could have become mouldy if left untreated.
Every one of these issues should have been remedied by Ford for free, so make sure the work has been carried out.

Try spraying some electrical contact cleaner into all of the switches on the main controll on the drivers door. With the vehicle running ignition on . It s likely just a bad connection water gets in between the window glass and the switches . If that dosn't work remove the main switch and clean the contacts and it will work again.

ALL ford focus do that you can not lock the car from the inside only the outside. Its to stop you locking your car keys from inside.

sounds like a window lift motor, maybe try and bang on the door a few times while you hit the button, if that doesnt work you may have to take the door panel off and test the wires at the window motor

go on ebay to by the key and then get it cut at like target or walmart...

once you get the new key...

1-insert and remove key from ignition two times

2-close and open driver door two times

3-insert and remove key once from ign.

4-close and open drvr door twice

5-insert key into ign.,then close driver door

6-turn key to on (not start) then off, twice this is rewrite mode

7-remove key from ignition,the door locks should cycle twice.if not start over.it may take a few tries.

8-press lock/unlock together and hold for a second

9-release,and press lock on remote,the door locks will cycle confirming program.continue to do other remotes you have,steps 8 and 9.if only one in possession,you are done. To end mode open door or insert key into ignition.

You'll need to follow the steps with no more than a 1-2 second delay between each step.. hope it works

it could be the switch on the door panel??? Are it could be the motor to the window. Take the door panel off, and jump the switch out. If it works by jumping the switch out. it will be and easy fix. It not, then you will need a new window motor. You can sometime pick an motor up for half price and your local junk yard. When you find your problem out and get it fix. go to the autoparts store an pick up a can of spray silicon lubercant, and spray it in your window tracks. over a pirod of time the window start dragging, causing the motor and switch to fail.

better left to mechanic not easy to do

check the diesel filter.it will be clogged,i am sure.Replace it.
