Some of you might remember that last spring I had a water leak in my truck and I thought I had it fixed after about 2 weeks of evenings and weekend sealing all the seams in the cowl trough, and the cruise control mounts, and anything else in that area I thought might be leaking. It stayed dry for awhile, but I'd kept a paper towel shoved up in the corner that was leaking so if it did leak it wouldn't get the carpet all wet. I periodically checked the towel and it was dry....But over the last few weeks whenever it rains, even just a little, the paper towel gets soaked! So now I am back at f-in around with this stupid friggin leak!
Anyway, heres the details. When it rains I can see water entering the cab from the upper left corner, behind the dash somewhere, I can see it run down behind the e-brake release mechanism, to the left of that square goldish trimed grommet that is(i believe) the main harness entry point.
I am getting pretty desperate because I cannot solve this, and I've spent countless hours at it. I am not really capable of removing the dash, this is my only daily vehicle...and I have work/school 6 days a week. My best guess at this point is that it is coming in from where the floorpan curves upwards and meets the cowl/body section at the very left corner of the cab. But I cannot access this point.
I was thinking about it earlier and I thought of two kinda ghetto ideas....But I wanna see what you guys think first, so I don't mess anything up.
-Buy a can of aerosol 'stopleak'...it's kinda like a spray sealant, remove the plastic wiper cowl cover again, and spray the exterior of that corner(around where the hood hinge mounts and stuff) and maybe down the side behind the cruise control box if I can.....I don't think I'll be able to spray any of this on the inside as it doesn't have a long nozzle on the can.
-Get some of that expandible foam crap, with a long nozzle on the can, and shoot it up into that corner from the inside.....Hoping this will plug the leak. My concern with this idea is that the foam won't plug the leak and will just make a mess, and then hold the water that comes in and make a bigger/moldy mess.
What do you guys think I should do?? as you can see I am getting pretty desperate for some kinda solution and I appreciate any feedback I can get on this.
