Car Leaking Water Inside Cabin

[minh]

Hey guys,

Just want to know if any one notices water leaking inside the cabin, or is it just mine.

Its not exactly leaking but the carpet is damp, where the passengers left foot would be if there was someone sitting there. I looked under and couldn't see any signs of water.

Something to note though, i did recently get my stereo installed and they did replace the battery and ran some cabling around that area.. please refer to the below pic.

Do you think where the cable is run - top left of the picture is where the water may be getting in?

I reckon it could be the culprit. Do you have the cover? Best bet is to grab yourself a hose, an assistant and on a slow stream run the water in the general direction. Don't force water into it just try and simulate rain.

yeah the battery is all covered up..

thats not such a bad idea.. might try that when the weather is a bit dryer..

cheers

I've run a heap of wires in the same place in my M35 & not had any water get into the car, even when driven in really heavy rain. Having said that, it probably is the cause of the leak, especially if the plastic trim that sits against the windscreen isn't totally flush with the glass. The water could happen to drop straight down the cut they've made in the rubber boot. Nothing some silicon won't fix though . Good luck.

Mate I've got the EXACT same issue. Water leaks into the cabin and gathers in the left rear passenger's footwell.

I had LPG installed a few months ago and they ran some hoses along the firewall area...I wonder if that's the culprit. The leak only occurs in very heavy rain...

I don't think my cover is missing, but perhaps something there is allowing water to get in? Hmmmmm

if I am looking at that correctly I reckon that the grommet has been cut and that the cable is forming a channel for the water to run inside.

I would take it back to who did the work on it and tell them you think you have a leak and get them to look at it. (looking at it I *think* I know who did the car.)

last one of those I did I put a 4 AWG cable through the end of that grommet neatly and resealed it with black sickflex. you can pull that harness down a fair bit and the grommet end will expand a fair way to allow a cable that size into it.

this should show what I am talking about

that entire harness has been pulled out , stripped and reassembled. it does not leak. compare that to yours

[Chris Rogers]

where is the fusing on that btw?

[minh]

yeah the more i look at it the more i'm thinking that's the culprit.

I might pull things apart and give it a dose of sikaflex. If i still have leaks then ill take it to the workshop that did the install which i'm sure will be more then happy to help.

Chris - the fuses sit to the left of the engine bay mounted on a piece of perspex.

Be careful of touching it, then going into shop. They may knock it back.

Also sorry, but where is the fuses? They should be as close to the battery as possible, if you have a short between the battery and "to the left side" of the engine bay, you will be in a world of hurt.

part of the reason I pointed it out. I can see the factory terminal low right corner but IF that battery moved an inch to the righ then that car is going to go up in flames. sorry but looking at it from my POV thats what I see. those batteries pack a fairly strong punch when shorted..
