Went to turn on the heat this morning, and nothing! I tore the glove box out and checked the fuses, they are good, the relay clicks but nothing comes on. The blower does not turn, and the AC light does not light up. They both did, just yesterday.

I jumped power down the the blower fuse slot, and the blower is working, it spun up just fine. So I'm thinking even though the relay makes noise, it has bit the dust! Other than powering up the relay, is there any other ways to test it to find out if I have another problem?

 

To update this, it was a bad relay. Just because the relay makes noise, it may still be bad.
