Hello,
This sounds to me like you have a short to power between the Body Control Module [BCM] which controls the rear window wiper and the windows and your blower motor wiring. In the diagrams down below I have included the wiring diagrams for your vehicle's Computer Data Lines and the Heating Ventilation and Air Conditioning [HVAC] circuits, including the blower motor, for your vehicle. I have also included a guide on how to find a short to ground. You will need to use a Digital Multi-meter [DMM] to use these guides, so here is a link below explaining how to use one, if needed:

Please go through these guides and get back to us with what you are able to find out.
Thanks,
Alex
