Water leak on passenger side carpet

I am sorry to ask this question as it’s been asked time and time again, It was not a problem then and I did not have the answer so I skipped the post each time. Well the carpet is wet on the passenger side floor in my 760T any HELP PLEASE? I know that the A/C drain is working as when the car is parked after a drive with A/C going there is a good amount of water under the car. Thanks for reading this and many thanks if you have a answer too.

Winston..I just solved the leak issue on a 85 760 Turbo with Harrrison ATC Climate Control...it, too dripped plenty of water this summer but still soaked the padding and underlaying foam. The rubber grommet ring which surrounds the drip tube where it passed thru the firewall had started to cumble and the water was passing back thru and running down the inside firewall and under the carpet. The tube on these automatic temp control systems is only a hard pipe that barely sticks thru the firewall and exits just below the receiver drier (big silver tank)on an angle. I puttey-ed all around the grommet with silicone caulk outside and did it just above the inner carpet edge inside and it is finally dry. Be sure to dry out the inside fiberpad and foam mat. You will need to pull the front seat to remove heater extension tube to lift mat.

I think the grommet crumbles from the heat..so much for an american (General Motors) air conditioning system..they should have placed a small down spout tube on the engine compartment end.

Have Fun!

Norm, Thanks for your reply, I was going to check it out last weekend but didn’t have the time. Hopefully I will get to it this weekend, thanks again to you and P,Dwyer

Winston: I guess from now on you'll be reading ALL the posts, eh?, just-in-case. Now: remove the passenger left kneewall cover: you should see a long (black?) tube= drain. You may have a blockage (algae, most likely) that is keeping the water from going OUT as fast as it goes IN from your A/C system. N.B.: get a long-nosed visegrip, you are NOT going to want to CRUSH that tube, but you are trying to keep any residual water from gushing out. Put a 2- or 3-gallon bucket on the floor, guide the disconnected tube to it, and release the "clamp", that should do it. It's not the most convenient place in the world, but you should be able to do the job. The other scenario: do you drive so crazily that your front seat passengers pee in their pants, which rolls down their leg, and onto the floor? If so, the answer is obvious, and even easier to solve than scenario #1. :>)...PD.

P. Dwyer, Thanks for your quick reply, I will do that little job at the weekend. I used to read all the posting but I don’t get too much time to do that now. “Do you drive so crazily that your front seat passengers pee in their pants, which rolls down their leg, and onto the floor?” I think you are correct about that, I think they have been doing more than a pee too there was always a bad odor from the passenger side (only when there is a passenger in the car)

Winston: part 2 re: your 'leak-in-the-front-seat' problem: when taking that drain tube out, take it out from the BOTTOM,or as low down as possible; that's where you want to put your 'clamp', too. If possible, once the water is out of the way, try to completely remove that drain line, see if there is anything blocking it. Wash it in water with some bleach in it (kills algae, etc., and bad smells. Look into its upper and lower connecting points, in the vertical concole, to see if any supermarket discount coupons, etc., might have fallen in...you got the picture. As far as that smelly goes, thsat was a sh**ty thing to say about your passengers; fun cleanin' up, amigo...."Pee" Dwyer.
