Introduction

Consider installing wind deflectors on the side windows. Very handy items!

Benefits, issues and risks

They reduce wind noise when cruising with the windows open, and enable you to open the windows a bit even when it is raining.

Also, having your windows opened a bit when off-roading is a good practice, because it enables you to hear better if a strange sound occurs.

When off-roading, an exterior sound can indicate the following issues of immediate importance:

• A tyre puncture;
• A sudden mechanical issue;
• A tree branch getting tangled in the underbody;
• An angry animal (or an angry land owner) approaching you;
• A land mine exploding under you or under a nearby vehicle;
• Agony of a living being caused by enduring the weight of your vehicle on it;
• etc.

Sounds are also useful to better ascertain the terrain that you are driving on (rocks grinding, wheels slipping, etc.).

General notice: Beware that it is not recommended to have the windows open just a little bit when you are driving on hard gravel, due to excessive vehicle vibrations which resonate hard on the opened window glass. Either keep the windows closed, or opened almost to the end, so that the bottom of the window frame dampens the vibrations towards the glass.

Original (OEM) wind deflectors are the best fit (and it is a tight fit indeed). Clearances on the top of the window frames are generally really tight for the moving side windows, and you do not want to harden the life of your electric window motors more than you need.

Installation instructions

For Jimny 3

The original wind deflectors P.N. 00800-87530-000 come with a paper installation manual which is also available here in a scanned form.

The installation is a bit of a "tense" job - the deflectors have to be bent hard in order to insert them into the window in the doors. It might look like they are just about to snap, so it is advisable to install them during warm weather and/or to preheat them a bit with a hair dryer before commencing with the installation.

After the deflectors slip inside the window in the doors, they are not bent any more - they fit "like a glove".

The deflectors come with taped glue on the "brow" which slips into the door. The tape should be removed prior to installation in order for the glue to make contact with the upper window frame.

However, if you intend to ever remove the deflectors later in the future, it is better not to remove the tape, so the deflectors do not glue inside the doors. In that case they will be simply mechanically held inside by friction. In practice, they rarely fall out. Even if they do start falling out a bit, just tuck them back in occasionally. If they happen to fall out often, you can always remove them, remove the tape from the glue, and reinstall them properly with glue for a permanent fix.

The door rubber seal can be taken off putting your fingernails between the door and the rubber from both out- and inside back-to-back, and then pull down. Clean the door window outline with isopropyl alcohol (IPA) and some cotton or a piece of cloth.

Attach the tabs to the wind deflector (consider the orientation, it should be a simple press fit). Remove part of the adhesive tape protector, make a fold so it stays in place.Fix the tabs in the window outline without pressing, it will hang and from there, move the wind deflector while sliding the tabs to have the best position, as indicated in the images.

(PRO TIP - at this point, put back the door rubber seal from both sides, just leaving the top uncovered; use a ruler to have the same open window height, and align the low end of the wind deflector to the window, so both are practically parallel, ensuring a symmetric look.)

Once aligned, take off the adhesive tape protector at all, make a firm press of all the wind deflector outline, ensure the door rubber seal completely covers the tabs and then completely put back the door rubber seal.

Just as some food, "keep in a cool dry place" and should be good to go.
