Have your refrigerant level checked for starters.

by any chance,did you drive in heavy rain?

RXSF

if you drove through a puddle, water may have entered the engine compartment where the belt is. It shuts down the AC as a precaution. usually restarting the car/turning off and on the AC again resets it.

Why dont u take your car to a mechanic. I think its not a big issue.

RXSF:

Is there any solution to stop the AC switching off when driving through a puddle?

Most likely the magnetic clutch relay failed. Ive done plenty of those on the older RX. Parts are around $70 and labor is $55. If the drive belts get wet the the car will shut down the a/c and you will see the light flash. All lexus cars have that.

It has to do with some safety of the compressor. Details escape me, but all I care is that it normal.

it is just a safety machanism. No big problem here. Just switch it back on after it switches off.

Wow,
I had no idea the described situation was a safety measure. I guess i just learned something new...

salimshah

Yep, safety of compressor and your pocket book.

Bonus points for who ever finds the reason behind it.

The reason behind it is if the drive belts get wet and start to slip, there are sensors on the pully that read this and shut off the compressor. If the belts happen to slip off, the the compressor locks up and the must be towed. Lexus
does this to prevent that from happening. Every Lexus car has this feature.
Also, if this a/c lights flashes when it is dry out then your Magnetic clutch relay is failing. It is a repair that costs under $200.
