Thank you very much for the concern expressed. Otherwise, I love the GXP Grand Prix. :shades:
Thanks

Has anyone experienced water filling up the area where the spare tire lays in the trunk? I have a 1999 Grand Prix GT and discovered the water in there last week.
The temperatures were below freezing and the tire was frozen in place in the area where it lays under the panel. Once my dad got the ice melted with a hair dryer, he had to bale the water out of the hole. It would have made a good fish bowl.
We kept a fan in it all day and also had to remove all of the carpet because it was soaked.
On a separate issue which led to finding the leak, I had to have my gas door replaced because one hinge had rusted away and the other was getting close. So the man who did my body work checked the trunk for leaks while he had my car and couldn't find any. He actually laid in the trunk while someone sprayed water all around the trunk, lights, spoiler, etc. and it did not leak.
So, we have no idea where this water is coming from.
Does anyone have any experience with this or any ideas?
Thank you,
Eric
When I bought this car with only 40,000 miles on it the first issue I ever had with it was when water started pouring out the back reading light on the driver side rear. I immediately took it in and they said a hose had just gotten loose and they fixed it. Here it is now 80,000 miles and not only is water coming pouring out the same light fixture , but also has escalated to come out where the roof meet the front driver side . My entire driver side roof is soaked , my seats, my floorboard , and now my new to me car is smelling of mold just like ever other car I have ever own. You have NO IDEA how that fact depresses me more then anything. If this is a well known error why hasnt there been some sort of recall. To fix the "hose falling off " issue.. I am not a mechanic so the idea of ripping my headliner down to try and fix this problem myself is not really a solution. Nor do I feel that a well known issue as this should be something I should be paying outlandish mechanic fees to just get fixed for what another 40,000 miles? This is ridiculous!
Does the car fog the windshield easily? A symptom of water inside the case from either AC water or heater leaking. BUT a heater leak smells like hot coolant, not just musty water.
Have a sunroof?
You have may a tube for the sunroof leaking? On Bonnevilles, they occasionally came off where they go through the floor board and the water from the roof drains into the cabin in the carpet area. The front tubes go down through the A-pillars and penetrate the floor. Must remove the carpet and rubber underlayment to get at the problem area. That might explain why parking uphill so the water around sunroof flows more to the back drains seems to help.
If you are losing coolant, it could be the gaskets between the lower intake manifold--I assume this is a 3800 engine--and the tops of the heads. These are usually replaced along with the upper intake manifold which is plastic and can also leak coolant into the engine near the throttle body. Does your oil on the dipstick show a brown color sort of milkshake like?

Other than that, you can feel the inlet and outlet heater hoses from the engine compartment. If one is warm but the other cold, then you may have a heater valve issue. If both are hot, and there's no air blockages, I'd have to say that you have a stuck blend door under the dash or one helluva clogged heater core.
What tube do you mean?
Let's do some "if's":
With the engine warm and the front of the car uphill on a driveway if possible, run the engine at 2500 rpm for 10 seconds or so, then idle, then repeat 4 more times. This will help move air from the heater core if it has been trapped there. Usually high engine rpms on the road will burp that air out, but maybe not in your case.
Feel the upper radiator hose after the car has been idling for 15 minutes or driven. It should be so hot you can't hold it barehanded. If it's not warm, let the car sit for hours. Then restart and keep feeling the upper radiator hose for hot water to start through it gradually. The thermostat might be opening too soon in that case. There should be almost no heating of the middle of that hose until all of a sudden the thermostat opens and the engine has reached 195 deg. F.
If the car is warm after driving for 15 minutes or more and the blower on the heater on low, feel both tubes to the heater core near the firewall.
Be careful of the moving belts and any loose clothing. Both should be very warm
If both are warm, turn the blower on high and wait a minute or two and feel again. The one tube should be cooler than the other but still warm. That's the return tube. The air flow through the heater takes heat from the water so the returning water is cool but not cold. You can have someone idle the engine at about 1500 and recheck.
If one is essentially cool and the other is warm, you likely have a clogged heater core with no flow.
If the system had DexCool in it that had been contaminated with other coolants when you started having these problem, the core may be clogged by that. If the car didn't have good maintenance, the DexCool may just have coagulated and clogged it. A reverse flush on the heater core may help open it some, and it may easily clog again.
A few may be able to use some cleaning chemical that will open it, but don't bet the bank on that. The typical flush the garages like to do to clear the radiator usually don't work on the heater core in these.
Replacement of heater core may be needed.
