What part do I need ot repair

So the blower motor doesn't work on any speed?Also do you have a multimeter to do some testing?

Well here is the problem unless we test some stuff and trace power and ground's etc we won't know what we need to replace. There is no replace this to fix the problem we could have a bad blower motor bad ground loose connection etc. Guessing is expensive and a waste of money. You could check the fuse's but without a multimeter and knowing how to use it it's going to be hard to figure it out. Do you have friend that might have a multimeter and know how to use it to help you out?
