2003 Lexus ES 300 air conditioner

2003 Lexus ES300
Blinking lite on AC … replaced Relay stills blinks now what?

.Some people replaced the magnetic clutch relay under the hood with success others had to replace the serpentine belt because it was slipping when going over a rain puddle… A blinking a/c light is never a good sign and should be troubleshoot and fixed by a qualified a/c technician.

Generally if the air conditioning compressor clutch slips the A/C amplifier with shut off the clutch and flash the A/C button light.

Check the belt, make sure it is tight/not slipping. Inspect the clutch, see if it slips when another person switches on the A/C.
