Outer Limits 4x4 Board

I know all soft top sierra's leak but this one is very annoying I have a water leak on the pass side in heavy rain, the water drips on the tray under the glove box and soaks everything on the tray, its the same leak I had on my SWB and I've seen it on another Sierra. Before I remove half the dash and do a water test does any one know if there is a common spot it comes from?

Maybe the little pipes on the firewall (engine side) are blocked. It can cause water to back up into the vent system. That'd be my first point of call.

Yep, check the drain tube for the plenum in the dash.

Layto....

ID say check the windscreen rubber seal and the seal between the airbox and body. This is where mine is leaking.

yup the little grill between the bonnet an the windscreen on either side of it there's a hole ..... they fill up with leafs happens to me all the time

air compessor fixes it

Such a simple thing overlooked the leaves twigs and dirt had blocked the vent. Blew it all out then washed it down, Then on my way home from work ran the fan and flicked the vents only to get showered in all that was stuck
Thank for the advice

mine leaks alot when up to the windscreen in a river

Knew it couldn't be that easy Monday morning had no less than 3" water on pass floor and again this morning. Checked the drains and plenum panel- All clear.

As was driving I noticed when I drive no drip when I stop it drips.

So... Out comes glovebox and it seems the water is running down the side of the window frame and saturating the foam rubber that sits between the frame and body then dripping on to the wiring harness then on my street directory untill that swells and can hold no more water then drips an the floor.

I am thinking (since I never fold the screen) of removing the foam or at least a channel along the width and running a bead of windscreen sealer (the old fashion stuff not uerethane) and see how that goes?

Has any one had this problem... or is it just me?

It only happens when it pisses down for ages like the past two days (our swimming pool has risen by 6" in 48 hour !)
