So the previous owner did not take very good care of her

the main problems are with the electrical aspects of the car, heated/power seats don't work, dash gauge back lights are out and my biggest concern is with the blower fan, I just got a power module by the blower for it and installed it today (previous owner said that it was blown). After installing it the fans came on and the heat worked fine, then it just decided to shut off, while it was running the dial wouldn't change the speed of the fans. After about 5 minutes the fans turned off and stayed off. It's very frustrating
