Hello all, I'm new here, but I hope someone can help me with this. My '04 4runner has had intermittent problems with AC light flashing on and off. Someone said change to new relay which I did. It worked for a while, but problem has come back . It seems to be OK for a while then will crop back up with no apparent reason. My mechanic couldn't find anything cause it was working OK when I brought it in. (OF COURSE!!) Any advice would be appreciated. Thanks
