Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
If you saw sparks there is a good chance the blower fuse was blown.
Look at the 50 amp Heater fuse link in the underhood fuse block.
If that blew then replacing it with the wiring repaired should restore your blower operation.
If it is not blown do you have a voltmeter to check the circuit if I guide you?
Yes it would, it is 29 in the link here
