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