DONE! what a horrible job! the rear panel is a nightmare to remove!!
anyway did a sort of DIY....so erm yea enjoy
First unclip the plastic cover on the wiper arm, Basically the edges can be spread out so it unclips off
Undo the jet, this simply just needs to be pushed up to fully reveal the nut holding the wiper arm
Once the nut is revealed use a 13mm socket to undo the nut
The next part may be tricky for some of you guys, My car it was easy as its still pretty new so nothing was seized, However spray a bit of WD40 where the bolt was if yours is seized.
Now do not hold the wiper arm but instead try and grip the area where the nut was attached, Try and wiggle the arm side to side a bit whilst pulling up. The wiper should pop off completely
Now you will need to open up the boot and this was the hardest part
use a torx key (t20) as shown below and remove the two torx screws on the plastic trim.
Once these are removed, use brute force to pull the trim down and away from the tailgate. I found initially pulling from the bottom left and inserting a trim removal tool to allow a gap to be created. (U can use a butter knife also)
Once i did that i could just about see the metal prongs and just use some force to pull the trim down working your way around. Have a look at the pic of the back of the trim below to get an idea of where the prongs are.
once you have successfully removed the trim it should look like this
Now i had a bit of a problem as some of the prongs were stuck in the body work to remove them use a needle nose plier as shown below and place it in the prongs and pull down they should pop out of the body work
You will the wiper motor and there are 3 nuts holding it
Unclip the water hose going to the motor, Just push up on the small black plastic and it should release the hose
Now carry on and undo the bolts i found it easier to remove the wiper motor and then undo the loom going into it, if you can remove the loom first then by all means do so.
After the bolts are undone and you undo the harness the wiper motors out. I then inserted a suitable screw into the water hose but applied PTFE tape and also a little clear silicone on the threads, Tightened the screw up and then wrapped the whole thing in PTFE. After i used cloth loom tape to tape the hose to the existing wires.
And i also taped the original loom which was removed from the motor to the other looms. I used cloth tape so it does not rattle!
Next insert your grommet be it glass or whatever, I used clear silicone around the inner edge of the grommet and then stuck the grommet on from the inside.
Then i used a fair bit of silicone around the edge inside to ensure a good seal so there are no water leaks. Have a look at the photo below to see how i "sparingly" used silicone LOL
Now all that is needed is to put the tailgate cover back on, Allow the grommet to dry but as it started raining i just quickly finished up. Tip when putting the trim back on ensure all the prongs are intact on the trim and line it up from where the wiper was removed first and work your way back down to clip it in.
ensure all the prongs will insert in and use the palm of your hand wack the trim in when you are fairly certain it is lined up.
Thats it all done
now if you busted something or i dont know....ask one of the knowledgeable people here not me
. Love you bye.
