Hey guys! gave the car a bath this weekend and when finished i found a nice wet carpet in front of the passengers side seat all the way up to the kick panel and around the foot area. I saw a previous thread about the problem with someone elses car but searched and searched and couldnt find it. If someone can locate that thread or give me advice about the leak would be greatly appreciated!
Take the cowl panel off and feel inside for holes. Also pull the fan motor and feel in there for holes. The bottoms fill up with leaves and debris, with cowl off, run a shop vac down into the fenders and vac out all the junk. My 66 was supposed to sit outside til I could get to it and it flooded, had holes in the cowl area and under the windshield.
I forgot to say it is a 67 GTO i will have to check it out tomorrow and take the cowl panel off. This might seem like a silly question but thatts right beind the hood and in front of the windshield right? and there was a thread that had car with a similar problem that i cannot find it was pretty detailed
Yes thank you thats the exact thread i was looking for! i tried taking the cowl panel off but i could not get the wipers off. they just pop right off correct?
nope there is a small tab underneath them at the post you need to get a small flat head on and push up, i use a paint stick wrapped with a clean rag on the cowl to rest the screwdriver on, there is a special tool for this you can probably get from the local parts store too.
Also check that the 2 foam blocks are still good (on both sides of the cowl, under it). Check where the antenna wire goes THROUGH the cowl. Like otheres said, clean out all the mung undeer the cowl, and down both vent plenums. There are plugs in the plenums, near the bottom that are hard to reach also. Worst case scenario, rot at the bottom of the windshield, UNDER the trim......leave this for last. Eric
where the cowl drains into the compartment behind the kick panel/ fresh air vent (if equipped) has 40+ years or dirt and debris accumulated and often clogs up you need to get in there and really clean it out. the water then runs down inside the rocker panel and exits right in front of the rear wheel, after I cleaned mine out I drilled a 3/8 hole through the bottom of the section so the water does not have to travel through the rocker
next time it happens i will have to put the towel on it! Its been nice here so i have been driving the car a lot and the carpet is dry now finally. Eric im hoping thats not the case the rot under neath the trin =( there appears to be some rust showing underneath it to, As soon as i get time i will take the wipers off and the cowl and do some investigating and searching. Than ill get back to everyone on this .this is something that must be taken care of!
