toyota camry ac light blinking

[zamil29]

Hi guys,

I am studying in michigan, usa and my ride is a used toyota camry 2000. My ac light keeps blinking whenever I stop at junction and hot air will come out. I have to keep switching it on again. I have sent my car to the toyota service center and it cost me $2000 to fix the problem. Then, I did the internet research and most of the main causes were about to change the magnetic clutch relay, which I already did. But, it only last for a couple of weeks then the problem is happening again.

Please help me, have a good day.

When idling check the magnetic clutch whether it is running. If blinking means it is going on and off. If clutch running fine then it is something else.

toyota cars are prone to such issues....My mech says it was likely due to the circuitboard...

check the gap of the clutch.
i dont know your specific gap but it should be pretty narrow.
too much gap and the magnet cant pull the clutch.this happen when driving very slowly or stationary.
when u rev past certain rpm,the clutch will engage again.

i am not sure abt toyota whole system but on a merc,even the old w124, the compressor wont engage if it detects low gas pressure.

Most air con system with pressure detector will cut which pressure is low, means not enough refrigerant to run the system....
