Water leaking in???

[383stroker_1]

Hey, I have a 2000 Grand Prix GT, and recently every time it rains hard the passenger front floor gets soaked. I could not find where it was coming from. I inspected all the seals on the window and door. I even tested them with a hose to see if they leak. Nothing. Then I noticed the blower was not working properly. After futher inspecting under the dash I noticed the water was coming in through the heater blower. Does anyone know how the water is getting in and how to stop it? I would like to fix this because the blower is rusting out and not working much anymore and I have had two small lakes now, lol. Thanks for your help.

Yes, there are rubber/foam seals around the intake cowling. They are either damaged or missing. Also, check the one long continuous one that seals the hood to cowl. Also if you do not have a cabin air filter installed, it's good idea to install one because it will provide additional sealing and keep water out of the HVAC cowl intake and keep debris out of the blower motor assembly. The water drips down the cabin side of the firewall.

Thanks for the advise I will see what I can do.

You losing any coolant? Does the inside of the car smell like anti-freeze? If yes to both, you may have a leaking heater core.

[383stroker_1]

no coolant lost, just water after a hard rain fall.

OK. Had a similar problem with a previous car. I finally found out that the water was leaking around the area of the windshield wiper housing. Not when the windshield connects but lower. I sprayed an air conditioning duct sealer and it stopped.

On a '97 - '03 Pontiac Grand Prix spraying sealer into the cowl area is not a good idea. The link below which also has pics shows the problem area. A passenger side cowl/intake leak is common. The problem is resolved by repairing and/or replacing seals and a cabin air filter in which a spot already exists to mount one.

This weekend this leak popped up. Seems to only happen in very hard rains (we're in Florida). It this seal around a moving shaft or would a little silicone work?

My 2001 GT does the exact same thing! Not with every rain even...usually a really hard one. Rain water pools in the floor of the passenger seat. I haven't worried about it too much since it's not coming in the window/door, etc. It is quite strange though.

If you go to a chain auto parts store (eg Auto-Zone, Advance, CSK), ask for the cabin air filter for a similar year Regal, as the probable "parts monkey" they have behind the counter won't be able to find it in the computer.

383STROKER 1....check out this link. I followed the procedures and my GP hasn't leaked since. I put a small bead of silicon in the groove of the rubber strip to hold it in place.

The above 2 lines are suppose to be one line for the link

383STROKER1...if the link I posted above doesn't work for you, I can email it to you if you'll let me know your email address.

Unless he is logged into Club GP your link will not work as you have it. There is a trick to it but I am not at liberty to provide it.

Also, consider this a WARNING. 383stroker_1's problem was an old post at least 10 months ago and we frown upon resurrecting or addressing old posts. There is no continuity.

Sorry, I was following THIS rule:

BE COURTEOUS: AVOID DUPLICATE POSTS
Do not post the same discussion more than once on a discussion forum or on many forums. Duplicate discussions can be frustrating for other members, especially for those whose time and energy is limited. Weeding through the same discussion in multiple locations can be not only frustrating, but down right annoying. Duplicate discussions will be deleted. Reposting the same message repeatedly can be interpreted as SPAM and could result in the loss of your membership. Also be conscious of your fellow members and avoid making meaningless posts for the sole purpose of increasing your post count.

Is there a gage to use to determine when a thread is outdated? I couldn't find any guidelines in the rules.

Yeah I could see why you misinterpreted the rules. But the rule above really doesn't apply in this situation. That applies to spamming and/or post whoring. Having the same discussion or issue in more than one forum or the same forum more than once. Or doing spinoffs of the same issue from your original post. The thread you resurrected was not an active discussion and old so it falls into the category below.

POSTING IN CLOSED OR OUTDATED THREADS:
If a thread has been closed, there is probably a logical reason for it. If you feel that the reason(s) for closure of the original thread are unjustified or wish further clarification feel free to contact any member of the moderating team. However, do not start a new thread about another closed thread.

Please avoid posting or voting in outdated threads. It merely clutters up the message board and makes it more difficult for fellow members to sort through the vast amount of information contained on the boards. If you have new and important information to add regarding a past discussion, feel free to start a new thread and if need be, add a link to the original thread.

__________________________________________________ _____

As far as a gauge that is up to the Moderator(s) based on the circumstances. A post just a month old can be classified as old. The best thing to do is use common sense. If you see the prior posts in the thread are old then it doesn't make sense to carry on a conversation with someone that had a problem 10 months ago. The issue was probably resolved by now.

Hope the info helps. Let me know if you have any other questions.
