Thanks for your reply hmac300 . Are all these considered relays? Or just fuses Sorry my husband is army and gone for a while so I am trying to fix the fan without a lot of money Would it be the big fuse like for fan 1 or maybe the one for hvac blower. I just paid to have leak fixed and was told after it dried up (fuse box) the fan should start working again Anything you could suggest would be greatly appreciated Thanks for your time.
