I have a 98 Accord LX. The mode control motor is not switching between defrost, feet, face at all. I bought a replacement at a junk yard, but it doesn't respond to the controls either. At this point I need to test the motor to see if it is any good so I can tell whether my problem is the motor or the wiring. How can I use a multi-tester or external power source to test the motor?
