Question about 2004 Pontiac Montana
I have a leak somewhere that ends up on the drivers side floor. When ever it rains or wash the van it happens. I lifted the carpet and started putting towels there to soak up the water. I noticed that the towel first gets wet up where the heat would come out area. With winter coming on, this rain/water will turn into ice and since there is wires going up the left side of the floor and getting worried about it.
I turned on the fan inside and closed everything up, went outside and poured soapy water around everywhere. I found bubbles at the mirrors and and the top of the windshield. Also a "Tech" told me that under the door rubber at the driver and passenger sides there is a piece of tape that is supposed to cover two assembly holes on either side but doesn't, so I caulked it and solved the leak that comes out the map lights. I also found that there was a crack in the sealer along the firewall to passenger inside fender allowing water to collect int the wiring channel causing the dreaded "lock" problem, which I had fixed by the dealer but they didn't fix the leak. The dealers and "Jet-set Execs"are the reason GM is hurting as their vans are OK. The fix was spraying RV Roof\Gutter sealant from the front after removing the wiper cover and spraying waaay in. Now I need to fix the one on the front that comes in above the passengers left foot and makes a spiders haven behind the centre cowl. Jim

I went to get a chip fixed at Autoglass Specialists today. The gentleman that did the glass repair said he had a Montana and it leaked from the roof rack. The water runs forward and pools at the top of the window and stars i rusting. He loosened up the srews. We were lucky and the blue locktite didn't tear out the screw bosses in the thin shet metal of the roof. He cleaned and applied urethane caulk. The dabs were about 1/8" thick an about a nickle diameter size. He said on his van he just removed the roof rack completely and selaed the holes. That solved his problem. We''l have to wait for the next rain storm after winter to find out on ours.

Hi. You have a water leak in or around the windshield and or vent somewhere in the front. Pull back the carpet where you know the leak is and then while you watch, have someone spray down the front end of you car. Watch for the water to start leaking in, then trace it to its source. If it is an area around the windshield or molding, the leak can be sealed with silcone. If its a open vent, repair accordingly.
