The cooling fan assembly manufacturer is Pacific Best, and it has the tow package one it. I found Pacific Best, the model number of the fan assembly is PF6217.
Just to run over the situation once more:
1. First start in the AM... Auto Climate Control left in "on" position overnight... (and FL is a really warm climate even over night). Vehicle starts, but fan does not. After about a minute or so, the fan tries to cycle on, but as the fan gets to speed it dies and fan stops. This pattern continues every 45 seconds, but the cooling fan never stays on.
2. First drive of morning, air passing over condenser causes A/C to blow cold. After about a mile or so, the fan comes on and stays on through the completion of the trip. Vehicle may be shut off and parked for a bit, and the fan comes right on and maintains speed when vehicle restarted remotely or with me sitting in the seat and pushing start button.
When I originally got the vehicle and until the fan unit failed, the cooling fans would always come on and cycle up to full speed and stay there, and that's the way I understand it should be.
Thanks for all your help.
