Blower stopped working, all fan switch settings. 30 amp fuse in glove ok, 50 amp limiter under hood ok. Blower motor tests ok. Hot lead good, always 13.5V, but ground lead always infinite ohms to ground no matter switch setting. Fan switch seems to test ok. Is there a relay module or something, and where would it be?

Hi:

What I suggest is to locate the blower motor resister. See if you have power there. If not, there is most likely a problem with the switch. If you do have power to the resister, you will need to check for power to the blower motor. IF there is power but the fan doesn't run, remove the fan and have it checked and replace as needed.
