I have a leak in a grommet on the rear door of my 2012 Mondeo (1.6 TDCI 115 PS). I've bought a replacement but I have no idea how to fit it. The wires going through the grommet all have large plugs on them and I can't see how they can pass through the new grommet.




Has anyone done this before? Any ideas appreciated.

If they are multi pin plugs or connectors you sometimes have to carefully remove the individual connectors from the plug. Pass them through the grommet then feed back into connectors.

Two pointers of advise, always disconnect battery to prevent risk of shorts. Plus tape cord to cables when you pull them through body. This allows you to pull cables back into place.

Have you tried the easier option of silicon sealing around existing grommets.

Did mine 15yrs ago and still not leaked.

Those grommets are really hard to get back in properly...I tried to pass the rear dashcam cable through once (wouldn't fit through), but then spent ages getting them to fit and seat properly back in the holes. It really wasn't simple. Is this the reason why yours are leaking? they are not fitted/seated correctly? I can't remember what I did.

I ran my reversing camera wire through the right hand one, once I'd removed the rubber sleeve I then had to persuade the plastic ring to unclip from the bootlid and again on the car. Re-attach the rubber sleeve to the plastic bit then push the whole thing back into the bootlid/car. Was the only way I could get everything to seat back together properly.


They were a complete ***** to do. Personally, I'd go with Mony Zetecs and slap some clear silicone on them.
