If the measured voltage is not within specification, substitute with a known-good field effect transistor and check for proper operation.
Replace the field effect transistor if it is proved that there is a problem with it.
Disconnect the negative (-) battery terminal.
Remove the glove box housing.
(Refer to Body - "Glove Box Housing")
