Blower fan not working

This depends on what is wrong with it. If the fan is the issue, then it could be around $100.00 but if this is a wiring repair then it could be much cheaper if you can repair the wire or much more expensive if you need to replace a harness.

Here is a guide that will help with testing the blower as we need to check to see if there is voltage at the unit and go from there:

If you don't have voltage, then we need to check the fuse and relay.

I am attaching the wiring diagram below to help with this.
