    Default Door Window Glass Alignment

    Back to the Red NSX that was waiting for the alignment service during the snow in January....

    7. Door window glass and weatherstrip
    First time when this NSX showed up to my place, I noticed that the rear edge of the door window glass was hitting the Front Pillar Retainer. It was very scary closing the door so I kept the window glass lowered slightly.

    Also, when the engine was not running, the window will move only about 10mm (half inch) from fully lowered position so the entire window related mechanical and electrical parts required some attention.

    The weatherstrip was not installed properly and because of this, it was already deformed and damaged.

    Although I had spare weaterstrip, we agreed not to replace it or carry out the full window alignment work on this occasion.

    On earlier model, you need to be very careful with the rest of the parts used on the door when replacing the weatherstrip or adjusting the window glass. The shape of the weatherstrip was modified on our NSX in early 90’s and if you just follow the workshop manual to replace the weatherstrip or adjust the window alignment, you may end up with water leakage issue even if you may be able to overcome the wind noise issue. There are several parts to be replaced/reviewed in relation to the spec of weatherstrip.


    So, as I didn’t have these specific parts in stock to match the latest weatherstrip and there is no point in aligning the window glass against the deformed weathertrip, decision was made to carry out the minimum alignment work. The aim was to prevent the glass from hitting the retainer and also at least let the driver to close the window without using hand to pull it up.

    It is best to remove the front/rear guide rails and the regulator to clean/replace the parts to improve the up/down speed of the window but for this occasion, minimum service was carried out.
    It was also making the ‘popping noise’ so greased the glass holder collar as well.

    After these tweaks and the alignment work, the window now goes up and down much faster than previously. Still, not like the NSX just arrived from the factory but good enough until we get the new parts for this.

    From time to time, some of the screws holding the retainer were corroded and very difficult to remove.

    I’m so glad to have this special plier with me when dealing with these corroded/rusty/damaged screws and bolts.


    Although it was for the minimum alignment work, had to spend several hours before I was happy to return the NSX to the owner. As expected, there was some wind noise created due to the deformed weatherstrip but better than hitting the pillar every time closing the door.

    Default Alignment, Caster

    8. Alignment
    Before going to the alignment place, I normally remove all of the alignment adjuster bolts, nuts and cams to check for any seizer as well as apply thin coat of dielectric silicone grease to prevent any future corrosion.

    On this NSX, both R & L caster adjuster mechanism was completely seized and couldn’t rotate it at all. It’s the bracket at the bottom of the compliance pivot.

    The good news for this NSX was that both R & L caster seized very closely each other and they were close enough to the factory setup.

    I’m not a fan of compliance pivot but in order to cope with this seized caster adjuster, I now have some procedures to deal with it. Not an easy job though...

    After the alignment, the car handles much better and finally managed to return the car to the owner.

    Another NSX visited my place recently. The owner bought this NSX recently and it was the beautiful Yellow Targa model.
    So many things were carried out so I’ll post them bit by bit….

    1. USA Spec PA11-HON (latest model)
    I bought the same iPod adapter several years ago and the owner wanted to have the same setup for his iPhone 3G. So, contacted the same official supplier that I used in the past and got it within a week. It was about GBP100.00 including the delivery charge and then paid about GBP27.00 for import VAT and handling charge for Fedex.

    These are the parts inside the box;

    PA11-HON controller, CD changer port cable, iPod interface cable, the standard manual and the updated additional instruction sheet.

    The latest model comes with this new iPod interface cable (CB-PA85) which has a dongle near the dock connector. This will enable the controller to cope with the different battery charge pin location on old/new iPod and iPhone models.

    After testing the new PA11-HON on my NSX, I decided to carry out the same test on this Targa model using the cable inside the boot.

    Unfortunately, the head unit didn’t recognise the PA11-HON and instead, I started to smell the burnt circuit board coating when I powered up the head unit. After inspecting the head unit, the ACC power line to the CD changer port was still fine but burnt. As there was no short circuit on the CD changer loom, it looked like the head unit was damaged in the past and I just made it worse by connecting the PA11-HON. Although the ACC line was still fine, I didn’t like leaving it like that so used jumper wire to reinforce the circuit track.
    After this treatment, the PA11-HON was successfully recognised by the head unit and ready for the proper installation.

    Originally, I wanted to use the same installation method as mine by using the connector behind the passenger seat.

    But as I didn’t want to find any issues with the CD changer cable, we agreed to plug-in the PA11-HON CD changer port cable directly to the head unit.

    You need to remove this cap with red warning label and plug in this DIN connector to the back of the head unit or to the factory pre-installed cable if you are 100% sure that the pre-installed cable was not damaged in the past.

    There is a blue 14pin connector wired in parallel with the DIN connector.
    For our NSX, we don't use this blue connector so please insulate it and secure it to avoid any short circuits.

    For your reference, with this particular cable, the ACC power was on pin#10 and the Power GND was on pin#3 at the blue connector.


    Time to review the layout of the controller and iPod/iPhone.
    We wanted to keep the access to the PA11-HON controller box so decided not to install it inside the centre speaker housing between/behind the two seats. Instead, we decided to install the controller inside the arm rest box like mine.

    I only have an old iPod Mini and I installed it inside the upper rear compartment of the arm rest box.

    As I don't own any iPhone, I used the cardboard for layout purpose.

    Normally, I don't want to drill any new holes on the interior panel and I prefer utilising/enlarging the existing holes.

    Considering the length of the iPhone and the dongle on the latest iPhone Interface cable of PA11-HON, it was obvious that unless I drill a new hole at the back of the upper compartment, I won't be able to place the iPhone like my iPod Mini installation. So, we agreed to keep the iPhone inside the arm rest box, the same location as the PA11-HON controller.

    At the back of the arm rest, there are lots of existing holes that can be used for the installation.

    In order to obtain the max free space after the installtion, it was decided to place the PA11-HON controller box as close as possible to the rearwards of the arm rest box.

    One of the existing hole was enlarged and similar size hole was drilled to the thin aluminium plate inside the arm rest box. This plate can be purchased from Honda and very cheap so you can always try different setup or go back to original. The rubber grommet was placed to protect the PA11-HON CD changer port cable and the installation was done.

    Depending on the dip sw position on the controller box, you can use another device on the AUX port. This feature was also tested by selecting the Disc #6 on the head unit.

    After the installation, I tested it with original iPhone as well as the iPhone 3G with the support from another NSX owner.

    When the iPhone is connected to the interface cable, you'll see a message on your phone display such as 'This device is not compatible...... Do you want to go to Flight mode....'.

    Just tap on the answer 'NO' on the screen and everything works fine including the battery charge feature.

    You need to use specific Play list name such as 'HONDA1, HONDA2' and so on but it was very nice to play music on iPhone with PA11-HON.

    It would be interesting to see what will happen to the music if the phone receives a call... Probably mute the music and ring tone through the speaker???

    Any way, after the installtion of PA11-HON and Bose speaker Amp refurbishment, the owner was very happy with the level of deep Bass even using the compressed MP3 format as the source.

    More to follow....

    Thanks Kaz.

    Super write up of install as well which will be very useful to many I am sure.

    Hi Kaz, I'd be interested in seeing your procedure for this...

    Cool PA11-HON What happens when phone rings ?

    Hi Kaz,

    "

    "

    Regarding your query of what happens when the phone rings, the music mutes and the phone ringtone sounds on the speaker. If you answer the phone by "sliding to unlock" the phone is answered. If you subsequently click the speaker icon, the caller is heard over the car speakers.

    Hi, WhyOne.
    It may be too late but I hope this will help for your future installation modification.

    Hi, NSXGB.
    I knew you will be after this information. I'll send you the detail over the email once I have proper photos. You'll need proper tools as you need to take out the compliance pivot which means that you will be disconnecting the two ball joints at the pivot. You must use the proper tool and not the cheap ones.

    Hi, Henry. Thank you for the information. That's cool!!
    I may need to get hold of iPhone for bench testing purpose ...




    Back to the Yellow Targe subjects;

    2. Audio Head unit volume ring and on/off switch
    Quite often, I came across with the volume knob on the audio head unit with small amount of rattle.

    On this NSX, it was rattling significantly. So, I opened it up and tighten it with Loctite 243 to secure it.

    Now, it feels much better.

    The owner was not happy with the existing appearance of the volume ring and the switch. It was scratched severely. So, new parts were ordered from Japan and now it looks much better.

    3. Targa Roof Weatherstrip
    When removing the roof, you need to be very careful with the roof weaherstrip.
    The owner reported that he was suffering from excessive wind noise and even water leakage around the door window glass. On arrival to my place, I noticed that the weatherstrip was not installed properly and the door window was not possible to fully close when the roof was in place.
