An occasional problem on this vehicle is the A/C Compressor Clutch Relay. Failure of the A/C Compressor Clutch Relay will cause the A/C light to flash when the A/C is turned on and the A/C will not cool.

2004 camry ac light blinking and throws hot air. Suggestions?


My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.

A/c light blinks


The only problem with your air conditioning light blinking in the 4runner is a bad relay. Toyota has updated the relay to part #90987-02028. Call your local Toyota dealership for this relay. You can buy it at the parts counter. It is about $65. It takes 1 minute to replace. This is the first thing you should do to troubleshoot the AC blinking light. I had the exact same problem with my 2003 4runner and this relay resolved my issue. This same procedure is for the Camry and other Toyota models with the same blinking AC light, but the relay part number might differ.
