I own a 2001 Kia Sportage. Over the past couple of weeks this problem has been troubling. After starting and driving along for about 10 minutes the heater and windows stop functioning. They just stop working and have to pull over to the side of the road and re start where both the heater and power windows will start working again. Yesterday I had the vehicle in for servicing another problem and mentioned it to the mechanic who checked the fuses et al but couldn?t seem to find the cause for this situation. Any ideas? Would sure be appreciated.
