Mode Control Motor Test
CAUTION:
During this procedure, if polarity of test battery is reversed, the mode control motor may be damaged. Also, do not run motor for more than a few seconds.
- Disconnect mode control motor connector. Connect battery positive lead to terminal No. 1. See Fig 1 . Ground terminal No. 2. Connect one end of a jumper wire to terminal No. 2. Connect other end of same jumper wire to terminals No. 3, 4, 5, 6 and 7 in sequence, then start back again at terminal No. 3.
- The motor may not operate the first time you connect the jumper wire to terminal No. 3, but it must operate when you connect to terminal No. 3 the second time (when you restart the sequence). If motor does not operate when jumper wire is connected to each terminal, check for binding door or door linkage. If door and linkage are okay, replace motor.
