Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to justanswer.com
Sounds like you have more then one problem. As far as the check engine light and od light there are stored codes in the pcm that will need to be read with a compatible scan tool. You can go to your local parts store or autozone as they will usually scan your car at no charge. Once you have those codes let me know what they are so I can assist you with the diagnosis and repair. For the blower you need to check for power at the pink/white and ground at the orange/black or orange /red depending on if you have auto climate control. If you have no ground I suspect a faulty resistor for manual climate and a speed controller if you have auto climate. If you have no power then you may have a bad relay or blown fuse. Let me know what you find.
