Leaking water under glove box

[snafu7x7]

When it rains I'm getting water leaking from under the glove box. Talked to a few guys they say there are gaskets on either side where the water that drain thru the cowl grill will drain out, if those are deteriorated it will leak into the car.

I'm looking at it though and I can't see how to get at it, whats the best way to reach it? Do I have to go in from the interior of the car or do I take the cowl off somehow? This is a 69 btw

thanks

Possible holes rotted in the bottom of the cowl ,this is a common problem . You will have to remove the heater box from inside the car ,it is not a fun job . Once the box is out you can inspect the botom of the cowl . There is a cowl repair kit if the rust is not to bad

You may also want to remove the air vent on drivers side and inspect that area also

It really helps to understand what you are facing by looking at a car with the cowl top removed. Until then it’s hard to visualize what is underneath there and why.

Youtube has some great video. Most will scare you to death. The "patch" options might work but only if you have holes near the hats.

Worse case is the entire cowl (upper and lower) need to be replaced. It's as expensive as it sounds.

At least on the 1969 model it looks easier (slightly) than the earlier cars.

My drain plugs beneath the cowl in my 2005 got plugged with debris that made it through the cowl slots. I cleared them to drain the water out.

I'm inclined to leave the those rubber "drains" out for better drainage. Anyone know why this might not be a good idea?

Thanks.
Edit: Sorry for posting in the wrong forum - should have been in the 2005. Don't know how to delete and/or move.

Cowl vent most likely, as I said in another thread magnetic sign rubber. Cut, paint and stick. Works great.

Ah yes, the dreaded cowl leak.
I had to replace my cowl to correct it.
