My blower motor suddenly quit. Disconnecting the blower underhood plug I can run the blower directly from the battery with no problem. Motor works perfectly with no ill sounds.

Agitating the blower speed switch gives me a relay actuating sound from under the dash but no blower.

There is voltage at the blower plug but evidently not enough to run the blower.

All of the buttons on the blower control dash panel function properly. Modes work fine.

Any ideas as to what do check next would be appreciated.
