Hi, I have a 2001 Seville SLS (100K miles) in which the driver side power seat is operable but malfunctioning. For example, when I push the 1 button for seat position 1, the seat will move into the automatic EXIT position and vice versa, or will not move the seat at all until I press it multiple times. Also, and most distressing, when I press any power seat button at all, the heater/ac, heated seat and radio will shut off or turn on. In sum, the driver side power seat isn't working correctly in any way. Thanks for your help!
In addition, I just had the heater/AC repaired, a new water pump and a new battery installed. The heat and ac are working fine now but they couldn't figure out the problem with the seat and the apparent short circuit to the heater/as and the radio
