Thanks to both of you. I thought they might be innerchangable. I just bought one on E-Bay for $129 US Guarranteed and nearly new. I have been going through all kinds of nightmares with dealership. They charged me $400 to troubleshoot my AC and put in a stepper motor. That didn't fix it so they wanted to keep it longer. I have heard horror stories of $4000 fixes so I went to work myself with a multi meter. Found cracked solder joints on the CC board
