Question about 1986 Buick Century
Hi there. i hope you can help me out. i recently inherited my mom's 1986 buick century limited, v6. when the car has sat out on rainy days here in vancouver, the front passenger floor pools with water.
i took the car into GM, believing it was a heater core leak. they replaced the heater core and the associated connecting lines, to the tune of $600, this past week. well, to test out if this fix actually fixed the leak, i kept it outside, in the rain, and much to my deflation, the floor pooled with water. :(
any direction i should be looking/heading folks? any insight would be most appreciated.
Some cars have DRAINAGE where the wipers come to rest under the hood. if this drainage is clogged it will fill with water and could find its way inside. so pop off that plastic there at the bottom of the windscreen and see if you have leaves dirt etc.. clogging things up.
also in the future. don't take this as an I told you so kind of thing but if it leaked when it was raining logically why would they suspect the heater core and not .... THE RAIN:-)
depending on the car you can try removing the front seat and pulling back the carpet. get the car NICE AND DRY. have someone running water down the windscreen with a hose and you in the 69 position inside the car looking at the firewall area. see if you can SEE where the water comes in and fix it. don't just PLUG the hole !!! find the leak on the other side. why? cause if its pooling on the other side its RUSTING on the other side and will cause you problems down the road.

Tricky, tricky, tricky...Well, if the heater core and all connecting hoses are not leaking, the only other place that I could see water coming from would be a leaky windshield. Have you looked up around the windshield to see if there is any moisture around the trim? If the heater core and hoses aren't leaking, and the windshield isn't leaking either, the only other possibility that I can think of would be that perhaps your passenger side door has bad weatherstripping/seal. There just isn't anywhere else for it to be coming in. It kind of bites that you had to replace the heater core if it does turn out to be a leaky window or door seal, but at least you can comfort yourself in thinking that you have a 1986 Buick that eventually would have needed a new heater core, probably sooner rather than later, and now you wont have to worry about it for as long as you'll own that car. Just be glad that you were able to get it replaced at a far more convenient time than having to get stranded somewhere or a time when you didn't have the funds to do so. Hope this helps. Try to stay dry and have a great day!

The most common area to leak is the windshield seal
