Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam. With your car, does this leak happen only when driving in rain or does it accumulate water when using the AC?
Understood. Do you have a sunroof? If so, have you checked the drains to see if they are clear?
I would open the sunroof, then use low pressure compressed air through the drains at each corner. If they do not flow then you will need to expose the hose and clear it out.If the drains are clear and it does not leak, then we need to look at a seam in the floor board that is not sealed.For this you will need to expose the area under the carpet that gets wet and see if you can find a seam not sealed or perhaps some corrosion that has allowed it to leak in.
