1LS400Lexus1

Any one know how to get rid of highway wind whistle? Before I bought my car someone but in a non-Lexus windshield and it does not look like they did a good job; there is some black silicone sealant on the edge. Does anyone else have a 91 LS400 that makes the same noise?

If that's the case you may need to get the windshield re-install. Make sure you don't have any roof mounted phone antenna( coil type). The coil type antenna can make the whistle noise too.
