Question about Ford Focus
The electric windows not working:--
If the windows don't
work, any of several issues is likely to blame, including no electricity, bad
switches, bad motor, damaged window regulator, or even a broken wire.
Automotive power windows use a switched motor to operate a mechanical window regulator. This regulator moves the pane of glass into the door.
To check and confirm the fault try this procedure:--
1) Open the fuse panel and check the fuses for disrupted elements. The fuse panel at the driver's side kick panel, or between the dashboard and the door. In some cars the fuses are mounted in the engine compartment, in front of the driver's side firewall. Check the fuses and replace if faulty.
2) Test the wiring harnesses from the fuse panel to the switches and from the switches to the window regulator motor. If the circuits test fine, then proceed to the next step. If a wiring harness is shorted or damaged, it will need to be replaced.3) Remove and test the switches on the driver's side door panel. Pry them up with a screwdriver and pull them free of the panel's opening. Disconnect the switch assembly from the wiring harness by pulling the adapter plug from the assembly. Test the switches individually by touching both sides of one switch with the circuit tester. Each switch will have two terminals, and if the tester is positive on both terminals while the window is activated, then the switch is good. Replace the switch assembly if any of the switches fails the test. Most power window switches come in assembled modules and cannot be replaced individually.4) Remove and test (if possible) the power window motor. Turn the armrest bolts and interior door handle screws counterclockwise, then pull the door panel free from the pop rivets. Behind the panel are a window regulator, the window glass, and the electric driver motor. The motor is usually located in the lower right section of the door. Unplug the motor from the wiring harness and unbolt it from the window regulator by turning the bolts counterclockwise. Pull the motor straight out, away from the gears. And check out if motor is receiving exact 12 volts at the terminals. If not then either motor is faulty or there is a confirm short if motor is replaced.
5) If all the above mentioned possibilities are checked out ok then the window regulator needs to be checked. Inspect the window regulator's joints for rust or stiff movement, if the electrical system is operating correctly. These joints can corrode or break, causing the window to stop working. With the door panel off, the window regulator can be removed and replaced by sliding the glass away from the track mounts, then turning all mount bolts counterclockwise and manipulating the regulator out of the door.
To check AIR CON Try this:---
1)Look first at the graphics display on the dashboard. If it is blank, or if the air flow controls do not work properly, the problem is in the control panel. Disconnect the battery first.
2)Remove the trim panels on the passenger side, unscrew the four panel screws, and detach the cables from the controls. Unplug the electrical connector and remove the control panel.
3)Listen for the blower motor to make sure that it is running, but not overly loud. Step into the car and play with the air controls on the dashboard to make sure the blower motor is making the appropriate increases and decreases in volume.
4)Start the engine of the car and allow it to run while looking at the compressor. Look for obvious signs of malfunction. Touch both of the hoses attached to the compressor. The larger one should be cool, and the smaller hose should be warm but not painfully hot.
5)Make sure the pilot lights inside the vehicle are working and the graphics display is lit. If these are not working correctly it might be the control panel or control cables. Find the control panel in a Ford Focus by removing the trim panel surrounding the air controls.
6)Bring the three small control cables out from underneath the instrument panel. Unplug the cables from the back of the control panel, and unplug the electrical cable before removing it.
Also check ,There is one air con relay and two fuses for the engine cooling fans.Check the coolant level or any coolant lean in drain line.
