NC has water under passenger seat?


I recently bought a mk3 mx5 with the PFHT and noticed a lot of condensation and thought maybe it was just small cabin problems, however I saw that the carpet under the passenger seat was damp so water is getting in somewhere.

I just wondered where’s the best places to check for a leak and also I could not find much information about the drainage holes for the PFTH roof so was not sure if these were still an issue on this version.

That makes sense doing the kit, good spot, and good price.:+1:
Just take care getting the old ones out, I’ve read you can mangle the thin metal if you go at it too enthusiastically with a lever or such like. And do use sealant as well when replacing the new ones for good measure.:+1:

Yes, I was worried about distorting the metal and maybe even damaging the paint and letting rust take a hold.
So, on balance, I decided to just seal the existing blocks with silicone sealant.
Worked a treat.

I ordered some and fitted them today, fingers crossed.

Added some sealant around the new clips just for a bit of extra protection.


Got our 2012 Venture PRHT in June and that was the first job I did, new scuttle grommets from MX5 parts and did the drivers side for good measure, silicone sealant on both for good measure.
Easy to follow guides on You Tube.
