Door Panel, Revisited…

Monsoon season is here this year. Heavy downpour on everyday. Although Pug can withstand winter season but it does not immune to rain. Been driving couple of weeks in the rain, water started to rest in the foot well inside the car on all places.

 

Today, I started an investigation on how the water can get through inside the car. At first, I thought it was the door rubber seal gave away or maybe the placing was not correct from the factory. I did a few adjustment but to a disappointment still with the same result.

Another point is…. how come all of the doors having the same problem. After a thorough check, I found out that it was not the door seal problem. The water somehow or rather managed to get into the car through the door card (door panel) clips. Something new to me…. I need to seal off those clips but what is the best method?

Ok.. here is the culprit. There was a faint watermarks running down from the clip hole (some of the watermarks in the above picture has been removed by me just to make sure the theory). Need to seal those holes. Then I remembered this article which until now it served me well in preventing water ingression.

Here are the things needed apart from the normal tools…

    • Clear silicone adhesive (cost: RM12.00)
    • Black RTV high temperature silicone (cost: RM22.00), I bought two of these as I need to do all four doors

 

Please refer to this article and this article on how to remove the door card / panel.

The tubes

Since I’m going to remove the door card, it is better to check the water passage inside the door. Make sure both water holes are clear from debris. FYI, by doing this check up, it may break the door membrane adhesive thus it may not work effectively to secure the door membrane to the door frame later on.

Tear off the door membrane carefully. Make sure nothing is blocking the water passage inside here, the bottom part is the most crucial area
Use black silicone to replace the OEM adhesive. A few centimeter on the top part was not cover with the silicone as that area will cover the door handle
Black silicone was use here as it has a smooth, soft and rubberize material which will bond and seal the door membrane effectively. Use the clear silicone to cover the clips as shown below. Black silicone is not recommended to be used at the clips as it is messy if not apply correctly.
It does not required to be a perfect application, as long as it covers the base of the clip. The base will sit firmly against the door frame
Congratulation, we’ve done sealing the possible way of water ingression into the car cabin. It may requires two days to dry off because of current weather. Anyway, one door off and another three more to go. Hopefully it will cure the problem once and for all.

You may need to reapply the silicone if you wish to dismantle the door card again in the future.

Note: How the water get inside the car…

  • When there is a heavy rain or if washing the car using a high pressure water jet, the water will get inside the door through the window frame and any water passage on the outer door frame. 
  • Then it will dripping on any cable, splashing itself on the door membrane and somehow drip on top of the clips. 
  • If the door membrane is not securely attached to the door frame, the water may get inside the cabin through the weak adhesive. 
  • If the water drip on the clips, it will pass through the clip hole and thus leaking from the door card. 
  • The early sign of leaking is there is water on top of the rubber seal along the door sill. Eventually, it will overflow and drip on top of foot well carpet.
