blower motor not working

First check the 40A BLOWER fuse in the fuse and relay box under the hood. There's also a BLOWER RELAY there too. if the fuse is good, the relay should click and switch on the blower motor when you switch it on. There are electronic controls involved too which are not so easy to tell you how to test so I hope it's a blown fuse. You might try tapping on the relay if the fuse is good and you wonder about the relay. If tapping on it makes it work, it's probably the relay.
