Dark screen problem

I recently purchased the four seasons fans and Caspers plug and play harness. The fans are not coming on. Can someone Please tell me what wires to move around , so the ecm will turn them on low speed and high? Thanks

Do they come on with the AC? I would start here....http://www.vortexbuicks-etc.com/troubshootgeneral.htm

The ac system is not charged at the moment. The factory fan came on, then I put the dual fans on and nothing. Thank you. Probably something stupid, I'll figure it out.

BTW there is only High with this harness. You followed these instructions? http://www.installationinstructions.com/109069.pdf

Yes, thank you

Check the pins where the Casper harness hooks on to your fan harness. They get pushed out.
