This car has been an absolute pain in the ass the last few years. Cooling, transmission, more cooling now electrical. I have taken care of this car since brand new performing all maintenance (scheduled and required) and I can hardly wait to be able to replace it with a non GM product.

Noticed that the blower motor would take one or two minutes to come on after starting the car. Now, sometimes the blower motor will not work at all or just on 5. When the blower motor is not working the headlights will not work on auto. The running lights and the dash lights are on though. Also the rear defrost doesn't work when the blower motor is not working. Dealer thinks it might be an ignition switch, BCM or wiring harness. I just replaced the eight year old factor battery thinking that might be the issue, nope. The battery never left me stranded I just felt that eight years was pushing it. Please advise if you know the solution and cost.
