3Rd Gen Lexus Gs300 A/c Light Blinking

[hellgrace5]

Hello! I own a Lexus GS300 3rd Gen.

The A/C light is blinking and aircond is not cold!

I tried swapping all the working relays with the a/c pump clutch relay and still it is flashing.

Any advise ?

Did a search of this forum and found this thread. Not sure if this will help, but there are other threads under this topic.

Yes i did search on the forum and came out nothing similiar :(

thanks for providing the thread but seems like situation is quite different.

Freon is ok, no leakage, swapped all relay with A/C clutch relay, fuses ok, new battery.

Help! :(

The following paragraph is from the 2006 GS300 owners manual but can be found in the owners manuals for other models:

If the air conditioning compressor does not operate, the

indicator of the ”A/C” switch will blink. If the indicator of the

”A/C” switch blinks even when the ”A/C” switch is touched

again, have the compressor checked by your nearest Lexus

dealer.

Let's hope it's not compressor failure but that was the problem the one time the A/C button light blinked in a previous Lexus I owned.
