Replying to: tidester (Oct 08, 2007 10:29 pm) I have a 2003 4Runner with the A/C light blinking. Is there any way to troubleshoot this problem myself, or do I have to go to a dealer?   the AC seems to work fine (cool air comes out), but then the light blinks and cool air dies.   thanks, john Replies to this message: nedzel (Jun 01, 2008 9:00 am) tidester (Jun 01, 2008 5:34 pm)

Replying to: jdickmann (Jun 01, 2008 8:45 am) I had the same problem with my 2003 4Runner. There was a TSB, but unfortunately my problem happened after the warranty so they did not cover it. TSB was EL011-015. The parts they replaced are listed as:   3672 CP 90987-02028 Relay   I don't know if your truck is having the same problem or how to diagnose it -- I described the symptoms and the dealer took care of it. The good news is that the fix was cheap (under $150).
