To replace the windscreen for a Nissan 370Z you have to remove the dreaded left hand and right hand A Pillar Mouldings. Not a complicated procedure, however, I am still yet to come across a mould that has not been damaged in some way by a clumsy windscreen technician or DIY guy.
All to often DIY enthusiasts and professional auto glass technicians begin this task by aggressively pulling and levering on the mouldings, assuming they are clipped in place. You could be forgiven for assuming this, as the mouldings appear to be in two pieces such is the outer profile (False join in outer mould).
However, using a heavy handed approach will almost certainly result in these fragile mouldings being damaged. Just for the record, these moulds are approximately $400/$500 Australian, at the time of this writing. In addition, the mouldings usually come as blanks and require painting on arrival, an expensive and time consuming exercise. Something you would rather avoid.
Good news! simply follow the list of instructions below and removing these moulds is easy. So buckle up, lets jump into it.
Step 1. Important Information About The A Pillar Moulding.
The moulding from the outside appears like it is in two pieces, however, it’s not. The moulding is a one piece moulding that also contains the rubber door glass seal. This seals the electric glass window shut. So, don’t start yanking on stuff willy nilly, you will cause damage.
You may also want to check at this point if the front windscreen is generic. Look at the badge on the front windscreen, if it does not say Nissan, its a generic glass. If it is generic, then this indicates that the windscreen has been replaced before. Xinyi (XYG) is a generic glass, as is Fuyao (FYG).
If so, the moulding could be damaged already and may have been stuck back in place with windscreen adhesive. This is a common practice used by many inexperienced auto glass technicians to fix up mouldings they break whilst being careless.
Step 2. Removing The B Pillar Trim
At the back of the door you will see the B Pillar Trim. You will have to remove this trim, as it has a screw behind it that fixes the A Pillar Mould in place from the back.
Three clips are used to attach this trim. The top clip is a locating clip (one that does not clip in very tight) These clips are good as a starting point to “pry trims” as they are easy to lever open. Once unclipped you can get your lever tool in further, close to the next clip. The closer to the clip the better when levering, you want to avoid bending the trim.
Start at the top with a plastic tool or trim remover and pry the first clip by gently levering it out. If its difficult to pop it may be glued in place as we mentioned before. Be extra carful if this is the case as not to damage the trim.
Once the first clip is popped, you will be able to get your tool in further to lever the other two which are fastening clips. The trick is to get your lever tool as close to the clip as possible, this will reduce the chance of breaking the clip, or worse the trim. (see image of removed trim, for profile of clips and screw)
Step 3. Removing The Door Seal
It’s easy and necessary to remove the door seal in order to reveal the screws that attach the moulding to the body from the underside. Removing this is very straight forward, just start by removing the the bottom plastic trim that covers the door seal at the bottom. (see image)
It’s removed by levering up and in. It’s held in place by several long locating slots and a couple of more standard clips up the front in the footwell area. Just pop these out by levering straight outward.
Once removed you will then be able to remove the inner door seal that goes around the door 360 deg. Important Tip. Make a mark with a pen as to where the mould sits by marking the seal and the car body. This way when you put the seal back you can align the pen marks assuring the seal is installed back in the same location as before. The seal has a varying profile that is required to go back the same way, so don’t just pull it out at random without taking notes. You can thank me for this later…
Step 4: Removing The Moulding Screws
Again, not a big deal, the A Pillar Moulding is attached by 6/7 screws that reside on the underside. You can now see these screws as a result of removing the door seal in Step 3.
Simply unscrew all screws and you will find there is also a plastic press clip/stud, lever this out too.
Step 5: Removing the A Pillar Moulding.
Now you have removed all of the screws you can now simply lever the Trim off. Be careful as the trim is quite brittle. That said the clips used to fix it in place are locating clips, so they do not take much force to unclip.
Starting from the top, put you lever tool under the moulding and gently pry it. Get your prying tool as close to the clips as possible to avoid any damage. Each clip that comes free allows you to lift the trim a little more, which will enable you to see the next clip.
Again be aware that if the glass has been changed before the last guy may have glued it back in place. This can make things a little more unpredictable.
So there it is, A Pillar Trim Removal for a Nissan 370Z.
