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


#2

.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.
