Answer
you have two different problems going on.. first. the heat concern is caused by a faulty blend door actuator. very common. it is located behind your radio.. a white box about 4x4". change it and that will fix that problem. second. your lighting concern is being caused by what is called a front electronics module. again a common concern. unfortunatley, you can by one used from a salvage yard but, you will need to bring it to a dealer to have it programmed. i hoped this helped   -b-
