Recently obtained my fathers '90 LS 400. Fantastic car! Can't believe the car has 235k miles on it. Solid as a rock / quiet as a mouse.
Q: What is the beep (about 5 secs) when I turn the car off? Continues when I remove the key.
Thx

Sunroof open?
That could be it. With 15 years on the car, the sunroof doesn't quite seal in the closed position and results in some wind noise. Tilting the rear of the s/r up slightly reduces the noise.
Thanks. Open S/R is probably the source of the beep...
