Condensation on rear screen?

Post by Warrior » Sat 23 Nov, 2019 13:04

I know this has been covered before but I can't get my head around this!

I have 2 Pingi moisture grabbing bags and one of those trays with the crystals in the top. The Pingis do a job and grab some of the moisture, the tray doesn't work at all, the crystals just form a lump and no fluid drops to the lower section. Maybe the Pingis are working too well?

BUT....the inside of the rear screen is always wall to wall in heavy condensation. It doesn't matter which way it's facing, whether it's wet or dry.

The car interior and boot are bone dry.

Any suggestions?

I can only think the crystals may be duff :( Try a different manufactures crystals...…………...mine has been in the car for 6 weeks and is nearly half full of water

I've got the same problem at the moment, think it may be the seal between the bottom of the hood and bodywork needs resealing. Had a similar problem a couple of years ago and found one side was leaking into the hood recess, sealed it up with silicon and all was OK but maybe it needs re-sealing again. I found that the carpet in the recess may seem dry to the touch from the outside but if you pull it back there could be water underneath, so might be worth investigating this.
