Water problem in my car

Hey all, I've posted on here before, I've posted primaraly in the brakes section to find out about an abs issue I've had and I've helped others in there. I have a question now about another issue that I have that I've tried diagnosing myself but haven't been able to and maybe someone else with a 97 grand prix can help shed some light on my issue.

When I got my car I noticed a dark spot on the front passenger side carpet. It was along the crease towards the back of the floor board for the front passenger and slightly around the console. I figured it was damp from maybe my brothers shoes so i felt it and sure enought it was wet. I tried to use a towel on it to dry it up after a day or two and it stayed there. I tried heating my car up really warm with the vents to dry it out with the windows slightly cracked (and trust me it was hot) and that didn't work, so I removed the trim along the bottom edge of the passenger door (its a 2 door) and pulled up the carpet to find a pool of water. shocked I threw the towel at it, let it soak most of it up and then like I tried before, I turned on my heat and let it warm up to dry it out. I kept the carpet pulled up for a week to dry it out and sure enough it dried up. Not thinking anything of it, I put it back down and put the trimming down, and about 2 weeks later noticed another water spot. Now getting pissed off, I pulled off the trim and pulled up the carpet (was at a friends house and I just happened to have a towel again) and I put that on it, soaked up the water, and in order to keep it pulled up I used some heavy duty jumper cables (worked quite well lol) and let it dry back out. Came home and my dad and I looked at it. We came to the decision that the water was coming through a small hole drilled through the firewall (we assume it was for a sterio system) and we sprayed water through the wheel well and sure enough water came through. We plugged it up and thought it was fixed. NOW . . . I was replacing the blower motor in my car because when it got really cold out whenever I turned it on, it wouldn't spin up on the lowest setting, then it would barely turn on setting 2, then on setting 5 it would turn but squeal so loud I'd have to turn it down, and I couldn't use it until it warmed up and even getting it to warm up was a chore because I had to have the fan running for it to heat up, so I waited for the anti-freeze to warm up then I turned on the fan for like 5 or 10 seconds at a time, then it would eventually stop. Well while replacing it I dropped a screw behind the carpet (never put the trimming back on after the last wet spell because I needed some of the trim off to replace the fan) and when pealing up the carpet to get the screw, well, its wet again. We get the fan out and it looks like water got into the blower motor. We have sprayed water through the leaf guard to see if water was coming through the air intake for the blower motor but we didn't see any water coming in (we put a lot of water through the leaf guard).

ANYBODY have any idea how water would be getting in and under the carpet (it looks like its going UNDER the carpet not above it) and how possibly water would have gotten into the blower motor?
 


use the search feature and your question shall be answered....most people have this problem...water is getting in by the blower because a gasket has come loose. remove the passenger side cowl where the wipers are. the gasket is probally just sitting there... you should then be able to see the blower in a square box...the water is getting under the cowl and is suppodted to be being deflected by the faulty gasket. sylicone it back in place and put a cabin filter for a 97 regal from autozone over the box where u see the blower. this will fix the problem
 
Wow, silly me. thanks for the quick reposts. They help a TON. Hopfully with a few extra bucks i can save myself replacing my blower motor a second time! Thanks guys!
 
Yea it cost 4$ at the dealer for that fix!

NICE! Good to know, seeing as I'm a college student, cheep = good. I think I'm going to do your fix, as well as install a filter. I live on a dirt road *boo* and it gets dusty in my car with my fan on.
 


I dont know why but in the parts lookup at my work for this car, the cabin air filter is listed.

Regardless, I had this happen to me within weeks of getting it... Very disappointed at first, but pleased to see theres an easy fix.
 
these are common leak spots

-the famous deflector issue
-blower motor rubber elbow gets clogged
-sunroof (don't even get me started)
-drainage holes under carpet
-windshield leak

I can't wait till the headliner needs to be replaced. :th_angry2:

T-tops have leaked for how long? The issue seems to be the rubber used. That deflector is quite possibly one of the worst designs I've heard of. Its uses a metal clip to hold it in place and deflect water, the one of the things that accelerate rust at an unbelievable rate. The whole thing naturally rusts and breaks.
 


Its all good, it turned out that my sunroof sliding rail was cracked, nothing a phone call to ed morad couldn't fix :th_thumbsup-wink:
 
You get the filter or the plastic shield?

Just the shield.

To me, you should not do the filter, for the biggest reason being it is a pain to get to. Why would I want to remove my windshield wipers once a year to change out a filter? Plus the fasteners will eventually break or not hold as tightly being removed many times.

Adding a filter here is not like where typical cabin filter are anyway, it just does not make sense to me.

Other cars of mine have filter and the design is not like this at all.

mine is the one piece. It is what two wiper bolts and three other screws IIRC. it took literally fifteen minutes to take it off and put it back together.
 
It probably looks cleaner but makes the filter change a PITA. I remember the first cabin air filter I changed, the entire glove box had to come out.
 


yay, I just picked up the pieces. The water shield was 5.05 and the filter (got it from gm cause I was there and didn't have time to stop anywhere else) was like 12 bucks. Donno if I could have gotten it cheaper from autozone or not, get it there next time.

I was GOING to pick up a 2 piece cowl but, uh, FRIKKEN EXPENSIVE!!1!
- it was like 150 for one of the pieces and 160 for the second piece. 300 for the whole thing??!?
