I found just one other thread on this and it describes my problem but not a real solution. One idea was to make sure the temperature sensor in the dash was unclogged and the other talked about the AC. My AC is there but doesn't work (I need some R-12) so I don't turn it on. It just started last blinking last week. Has anyone else seen this? Is it a sign of an issue or should I just ignore it -- the rest of the controls seem to work fine.
in case anyone has this issue, I found this short discussion about it. Maybe all the times I've had the intake off, something got unplugged.

Or you could ask the etc why its blinking by running codes.
Ah, the one place I forgot to look -- coolcats. Thanks Haystack.
ok. so I got a 01 Blend door actuator out of position error. Going to search this forum and others on how to deal with it.
Didn't find anything on this issue but the problem seemed to magically go away. I did find another thread on this forum where the same thing happened to another guy. It blinks for a while (a month or so) and then stops. Very strange.
