Dan,

Have you connected BOTH fans directly to power (12 V & Ground)?

Also, there are THREE relays that control the fans (along with the PCM) - you only seemed to mention TWO in your previous post.

If you would like, I can color the schematic to show what should be on for both LOW & HIGH settings. Let me know.

Take care,
