How To: Replace Window Regulator On R33 S2 Coupe

[matticus]

Hi All,

My drivers side window regulator broke recently and after looking and asking around, i got a new regulator from Nissan (no motor) which needed installing.

This tutorial will be good for you is you have a S2 R33 coupe where you need to change the regulator and/or the window motor.

I didn't take any pictures but if I get a chance ill pull the door apart again and get some.

Just a note before hand, i really recommend getting the plastic inner weather shield from Nissan as your old one will probably get torn up in the process.

1. Get all required tools and parts

a. Long 10mm socket

b. 12mm socket

c. 3" socket extension

d. Phillips head screwdriver

e. Fat Phillips head screwdriver (only required isremoving motor from regulator)

f. Flat head screw driver

g. Grease

h. Whatever parts you need (recommended to also buya new weather shield (80860-22U00)

2. Wind down window to the bottom

3. Undo the three screws along the bottom of thedoor trim

4. Remove the plug in the door pull cup and undoscrew

5. Remove pull cup and window switch assembly andunplug

6. Pull off door latch surround. Trick to doingthis is to use a flat head screwdriver to undo the clip at the top of thesurround. Just wedge the flat head between the surround and trim and flick thetab off.

7. Remove door trim. Start pulling from the bottomand remove.

8. Unscrew door handle support.

9. Remove speaker shroud (4 screws)

10. Remove plastic weather shield

11. Remove any extra glue still on the door panel.

12. Remove car to back of mirror and unbolt themirror.

13. Unscrew belt moulding at end of door.

14. Remove belt moulding

15. Unbolt the 2 fabric covered window guides

16. Unbolt the two window stoppers (next to thewindow guides)

17. Plug the window switch back in and wind thewindow up about 2 inches till you can access the bolts holding the window tothe regulator

18. Get someone to hold the window while you unboltthe window from regulator (2 nuts)

19. Pull the back end of the window from the doorfirst and bring the front through the back too.

20. Unclip the power to the motor

21. Undo the 6 bolts holding the regulator on.

22. Remove regulator and motor.

23. If you have a new regulator and need to swap themotor over then you will need a short and fat Phillips head.

a. I ended up making one but getting a large Phillipshead and grinding it back.

b. The three screws which hold on the motor arevery tight and easy to damage so be careful!

24. Grab your new regulator and adjust it so thegear and motor will line up and hold it in place with a vice grip.

25. Screw motor onto new regulator and make sure itis tight.

26. Grease up all teeth on the new regulator and themoving rails.

27. Before you put the regulator and motor assemblyback into the door, hook it up to the wiring and test it.

28. Slide the regulator assembly back into the doorand put back the 4 bolts and 2 nuts to hold it in place.

29. Connect the power to the motor and test itagain. Make sure the regulator is in a position where you can bolt the windowup again (about 2 inches from the bottom of travel)

30. Slide the window back in the opposite from howyou took it out. Be careful not to scratch any tint you have on it.

31. Line the window up with the regulator and screwin both of the nuts to hold it in place.

32. Move the window to the bottom position.

33. Bolt on the window stoppers at their lowestposition and tighten.

34. Bolt on the window guides at their lowestposition and tighten.

35. Reattach the exterior belt lining and screw inplace.

36. Wind the window up as far as it will go. Do thiswithout auto up.

37. While outside the car, close the door. Measure thegapping front and rear to where the window should be. Remember thismeasurement.

38. Wind the window down again a little and readjustthe window stoppers up the same amount as the gap (mine was about 7mm)

39. Tighten the stoppers and retest where the windowends up. If the stoppers are too high the window will get stuck on the outsideof the door.

40. Once it is in a good position wind the windowdown again.

41. Get your old (or new) weather shield and put itback on the door. Again, I suggest getting a new one from Nissan as it islikely you will test your old one.

42. Screw the speaker back in place.

43. Screw the door handle support back in place.

44. Reattach the mirror and replace mirror cap.

45. Put the door trim back on the door and tighten 3screws along the bottom.

46. Replace the pull cup/window switch assembly andscrew it in place (put the plug back in the pull cup too)

47. Once again, test your window. Might be a good idea to give it a clean now too!

Well, i hope this helps someone in the future, if you have any questions, shoot me a PM.

Hey mate if your window is stuck on the up position how would put it down?

[jhjones]

Depends whats broken. Regulator, motor, relay or switch? If it's the regulator can't you just guide it with your hands?

Mine might be the regulator but i cant seem to put the window down,
