Vehicle Won't Start After Rain, Cold Weather

[Malpaso]

Hello

I have an 07 RX-350 with very low mileage.

I tried starting it this morning and all I hear is a fast clicking noise. The engine doesn't turn over. There was a lot of rain and snow last night and the temperature dropped to freezing (not sure if this might be related).

I have read some posts and they seem to point to either condensation or a loose connection on the wiring somewhere.

Have also heard that the distributor cap might be the problem.

Any advice much appreciated.

Thanks

It's probably a dying battery, especially if it's the original battery.
