How can you stop rain water from leaking through comfort system into Buick LeSabre?
Assuming this is a front door leak? The problem is probably a worn rubber seal where the glass meets the window (where window comes out of the door). For temporary fix, I sealed the area with electrical tape (window up) and it works fine. You have to also tape over the switches for that window too or you will constantly be replacing the tape or maybe even a window regulator........very very expensive. I took my car to the dealer originally and they said it would take a long time to find a window leak. I'll bet they already knew what it was. When I got home and really looked at it it was a no brainer. Of course, the final solution is to replace the original rubber seal.
Why is your heat not working on your 1978 Buick LeSabre the radiator was leaking antifreeze so you put some stop-leak into it and it worked but now the heat is not working?
I'm assuming that by leaking nutrients you mean the plant is loosing nutrients through the roots rather than absobing them. if this is the case then the root system is damaged or dying, in this case the plant will exhibit sysmptoms similar to that of overwatering - the progressive yellowing of the leaves and stems from the base of the plant upwards, and possibly even wilting if the temperature is to warm
