Rotate the engine clockwise only between adjustments

(a) Turn the engine switch on (IG).

(b) Halfway open the power window by pressing the power window switch.

(c) Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 1 second after the power window is fully closed.

(d) Check that the AUTO UP/DOWN function operates normally.

If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time. If not normal, follow the steps below.

(1) Disconnect the negative battery terminal for 10 seconds.

(2) Connect the battery terminal.

(3) Turn the engine switch on (IG).

(4) Halfway open the power window by pressing the power window switch.

(5) If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time.

If not normal, follow the steps below.

(6) Turn the engine switch on (IG).

(7) Halfway open the power window by pressing the power window switch.

(8) Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 12 seconds after the power window is fully closed.

(9) Check that the AUTO UP/DOWN function operates normally.

From the owner's manual:

If your vehicle has

the dual power sliding doors, both doors will have

to be reset. To reset a door, do the following:

1. Check to be sure the power sliding door is

unlocked and securely closed.

2. Turn the ignition to LOCK.

3. If the power sliding door overhead console

switch is in the override (deactivation)

position, return to the activation position.

4. Open the sliding door using the remote

keyless entry transmitter, overhead console

switch, or passenger switch. Allow the door to

travel fully open.

If the door does not travel to the fully open

position, press the overhead console switch to the

override (deactivation) position and slide the

door fully open and closed. Check for foreign

objects in the tracks. Repeat the procedure starting

with Step 1. If the door resists travel to the fully
open position, see your retailer for service.

The best way to adjust the TP position sensor is by a scan tool. With the accelerator pedal fully released the value should be between 9.8% - 18%.

You back probe the sensor,then turn on with the key, engine off
& take voltage readings.

Ohm meter is a waste of time.

All automotive work involves looking for voltage drops

You need your vehicles wiring diagrams

Your going to have two sensors on any TPS,
one 0 to 5V & one 5 to 0V when you open & close it

If not close to that, then it is either adjustable or worn out

Open the window with the local button and keep the button pressed for 3 seconds after it has fully opened. Then close the window and keep the button pressed for 3 seconds after it has fully closed. This calibrates the position of the window which it lost when you changed the battery. Good luck

I haven't personally worked on the Charade before, but the process on all 3 cylinder engines is the same.

The firing order is 1-3-2 and because there is an odd number of cylinders you will never get a situation where the inlet/exhaust valve on cylinder x is fully closed leaving the inlet/exhaust on cylinder y fully open (in contrast to engines with an even cylinder count).

Instead, you just choose whether to start with the inlet or exhaust valves first and then adjust cylinder 1. You then turn the engine over by hand until whichever valves you chose to start with are fully open on no.3 and adjust those and then the same on no.2. Starting again at no.1 you then do the remaining valves, so if you started with the exhaust valves, now you do the inlets.

Hope this helps, if so please return the favour by taking a moment to rate my answer.

lubricate door hardware, locks, etc.

H Kim -

The "gearbox" is unfortunately under the headliner with no easy access. If you are also experiencing a clicking sound when the motor is activated, the regulator track had slipped position and will need to be reset.

I have been through this problem twice now. The first time the motor / gearbox came loose from it's mounts, began slipping (click, click,click), very nasty sound. I remounted the motor with threadlock on the screws, but alas.. two years later (mine's 2006) it slipped again.. I don't know why yet, I need to drop the headliner once more and have a look. If you would like a copy of your FSM, drop me a line.

Here's the RESET procedure from the FSM, absolutely gospel, no other way to fix it:
Sunroof Motor Assembly Note: Note • If the guide is removed, initial position setting of the sunroof motor will be required. After installing the sunroof unit, perform initial position setting using the following procedure. 1. Press the TILT UP switch to fully tilt up the glass panel.
2. When the glass panel reaches the fully tilt up position, temporarily release the TILT UP switch and press it again for approx. 13 s continuously. Continue pressing the switch until the glass panel automatically stops at the fully tilt up position after reaching the mechanical lock position.
3. When the glass panel stops at the fully tilt up position, temporarily release the TILT UP switch, then press it again within 5 s and hold.
Note • Press the TILT UP switch continuously until the glass panel opens to the fully open position, returns to the fully closed position and then stops. 4. Release the TILT UP switch when the glass panel stops at the fully closed position.



ALSO, Here's the clearance adjustment specs for having the glass panel in the correct resting position:


GLASS PANEL ADJUSTMENT
1. Fully close the glass panel.
2. Measure the gap and height difference between the glass panel and the body.
3. Loosen the glass panel installation screws and move the glass panel to adjust.


Standard clearance a: 0.2-2.2 mm {0.008-0.08 in} b: 0 mm {0 in} 4. Tighten the screws.
5. Insert any available thin plastic card between the weatherstrip and the body, and verify that they are sealed. (There is resistance when the plastic card is moved.)


• If they are not sealed, perform Steps 3-4 and adjust again.

Run the top so the decklid opens, and down inside the top stow area there is a ~3" square access door for manual operation of the pump. Make sure the valve is tight!

I have seen many many 2008s that were never tightened enough from the factory.
