Before proceeding with module replacement, check the following
to ensure motor winding section is functional. With control module
removed and unplugged from winding section:
1. The resistance between any 2 motor leads should be similar.
2. The resistance between any motor lead and the unpainted
motor end plate should be greater than 100K ohms.
If motor winding section fails one of these tests, it is defective and
must be replaced.
