Any ideas? Relay maybe?
What you're looking for starts on page 8.

Looks like the low speed fan comes on with the AC. When you say it works fine with cooant temperature, I wonder if you are seeing high speed only? Maybe your low speed relay or motor winding is NG. Sould be easy enough to troubleshoot, now that you know how it works (after reading PDF).
