Check this out mate:Just done this - easy peasy. Thought I'd share it!
Tools required:
14mm Socket/Spanner
Philips screwdriver (not a stubby)
Blade screwdriver (to prise stuff out, gently)
Drivers Door
There are a few hidden screws that you need to remove to get the panel off. Other than that, should only take about 5 minutes off, and 5-10 minutes back on again! Ignore the seatbelt stuff for non-J-Spec cars.
All the screws are Philips.
1. Open the door and fully wind down the window!!!!!
2. Near the door hinge there are two screws with plastic surrounds - remove these.
3. Remove the inside door handle surround - this just pops out. Be gentle - you will need to pull the handle out to assist removing this section of trim.
4. The electric window switches have a handle section with felt at the bottom. Under the felt there are two screws to be removed. The switch can then be gently prised out and disconnected.
5. Under where the switch is located there is another screw to be removed.
6. Using the spanner/socket remove the lowest bolt for the seatbelt. Be careful to retain the washers, etc. Note the fitting orientation.
7. Where the belt goes into the door panel there is a small plastic "neatener". Remove the three screws and take this off (not sure if you actually need to do this!)
8. Take the top seatbelt "neatener" (triangle shape) off - it just clips off - to expose the top bolt. Undo, and again be sure to keep all the washers, etc. THIS IS IMPORTANT FOR SAFETY REASONS. Note the locating pin that allows the belt fitting to rotate towards the front of the car, but not backwards.
9. On the front (roadside) there is a round plastic filler near the top (the other side to the seatbelt bolt) which should be gently removed. Under this you will see another screw that needs to be removed. Undo this, but BE CAREFUL to keep some pressure on the screw to stop it falling into the door space. Remove the top inside section of the door that this screw held - there is a clip to pull out at the bottom. Use something like masking tape to secure this screw in place to stop it falling into the door space.
10. There are two remaining screws exposed by removing the top section of door trim. Remove these.
11. At the bottom of the door panel there are about 4 "bullet" clips that keep the panel snug to the door. Pull gently from the bottom to free these clips. They may break - they can be replaced with standard units from a motor factors or scrappies (my replacements came from a Cortina!)
12. Once the panel is free at the bottom, lift upwards to move the panel lip around the window - the panel should then come free.....
Do what you want with speakers, etc.... I replaced the standard 16cm speakers (8W hitachi, 25W max. WOW - such quality - thanks Nissan) with replacement 16cm speakers - they just went straight in! Even the screw holes lined up. If anyone wants to know I used Pioneer TS-E1675s (couldn't get any 1695s). You can also remove the metal surround that the speakers sit in with a few more screws in case anyone wants to modify, etc.
Replacement is the reverse order of above, noting the following points.
1. The panel lip needs to be placed over the top of the door and gently encouraged down to give the correct window gap, before doing anything else with the panel.
2. Reengage the "bullet" clips at the bottom before doing any screws, etc. You can feel where the holes are, put the clip in the hole and firmly tap into place.
3. Don't do any screws up too tight - you may strip the thread (like I did on one of them!)
4. Keep the round upper trim hole open until you have replaced the panel and upper section of trim AND seatbelt mounting point. You can look through this hole to make sure the seatbelt bolt is seated properly.
5. MAKE SURE THE SEATBELT BOLTS AND FITTINGS ARE CORRECTLY LOCATED. DO DO THE SEATBELT MOUNTING POINTS UP TO THE CORRECT TORQUE - THESE SAVE LIVES, DON'T COMPROMISE!
Passenger Door
This is virtually identical to the drivers door with the following exceptions.
1. There is a proper handle on the passenger door - prise out the two rubber stoppers in the handle to access the screws holding the handle and panel to the door.
2. The electric window switch can be difficult to remove (although its likely to be loose on many cars!) - Just wiggle until it comes out. You can also use this as an opportunity to "massage" the clip for a better fit when you put it back!
I hope this helps someone - knowing where the hidden screws are can save quite some time, and broken trim!
No, red is a colour but Black just looks better IMHO
