Pinpoint Test E: The One-Touch Up/Down Feature Is Inoperative
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
- E1 CHECK FOR POWER (B+) LOSS DURING FRONT WINDOW OPERATION NOTE: If window motor has one-touch-down operation with no one-touch-up operation and has been initialized, the smart window motor needs to be replaced and initialized.NOTE: The smart window motors are not on the multiplex link.NOTE: A new smart window motor is in proportional up/down mode until initialized. Refer to DOOR WINDOW MOTOR INITIALIZATION in this article. NOTE: The smart window motor must be initialized whenever the following occurs: the motor has been removed, a new motor is installed, a new window regulator is installed, a new window glass is installed, a new top run is installed and when carrying out any operation in which grease or lubricants are applied to the window system.
- Verify if power (B+) (circuit 30-AJ80 {RD} {LH front}, circuit 30-AJ71 {RD/YE} (RH front}) is lost during front window operation.
- Is power (B+) lost during front window operation?
- Yes : RAISE the front window to the fully closed position. MAKE SURE the window glass stalls into the upper header seal. Normal functionality should resume. TEST the system for normal operation.
- No : GO to E2.
- E2 INITIALIZE THE FRONT WINDOW MOTOR
- Key in ON position.
- Carry out the front window motor initialization procedure. Refer to DOOR WINDOW MOTOR INITIALIZATION in this article.
- Are the one-touch up/down functions operating correctly?
- Yes : The repair is complete. TEST the system for normal operation.
- No : GO to E3.
- E3 CHECK THE FRONT WINDOW CONTROL SWITCH
- Key in OFF position.
- Disconnect: Front Window Control Switch.
- Carry out the front window switch component test. Refer to COMPONENT TESTING for component testing.
- Does the front window control switch pass the component test?
- Yes : GO to E4.
- No : INSTALL a new front window control switch. REFER to WINDOW CONTROL SWITCH in this article. TEST the system for normal operation.
- E4 CHECK THE FRONT WINDOW SWITCH TO FRONT WINDOW MOTOR CIRCUITS
- Disconnect: Front Window Motor C524/C608.
- For the LH front window motor, measure the resistance between the LH front window motor C524-3, circuit 7S-AJ41 (YE/BK), harness side and the LH front window control switch C504b-5, circuit 7S-AJ41 (YE/BK), harness side; and between the LH front window motor C524-1, circuit 8-AJ42 (WH/GN), harness side and the LH front window control switch C504a-11, circuit 8-AJ42 (WH/GN), harness side; and between the LH front window motor C524-4, circuit 7S-AJ40 (YE/GN), harness side and the LH front window control switch C504a-5, circuit 7S-AJ40 (YE/GN), harness side.
- For the RH front window motor, measure the resistance between the RH front window motor CB08-3, circuit 7S-AJ47A (YE/BK), harness side and the LH front window control switch C504a-3, circuit 7S-AJ47 (YE/BK), harness side; and between the RH front window motor C608-1, circuit 8-AJ56 (WH/GN), harness side and the LH front window control switch C504a-2, circuit 8-AJ56 (WH/GN), harness side and between the RH front window motor C608-4, circuit 7S-AJ48A (YE/VT), harness side and the LH front window control switch C504a-9, circuit 7S-AJ48 (YE/VT), harness side.
- Are the resistances less than 5 ohms?
- Yes : INSTALL a new front window motor. REFER to FRONT DOOR WINDOW REGULATOR AND MOTOR in this article. INITIALIZE the window motor. Refer to DOOR WINDOW MOTOR INITIALIZATION in this article. TEST the system for normal operation.
- No : REPAIR the circuit(s) as necessary. INITIALIZE the front window motor. Refer to DOOR WINDOW MOTOR INITIALIZATION in this article. TEST the system for normal operation.
