Rear vents on my van don't open or close

does your roof opening panel work (sun - moon roof ) ? Same fuse powers vent windows . fuse # 110 30 amp maxi fuse .

There are 3 switches above the rear view mirror. The middle one controls the back windows. Push up to open and down to close.

First you need to find out if there is power and ground at the switch if both won't work,if no power there then look for a blown fuse in PDC under hood. Check them all as it may be on a different circuit,also check wire harness from the door into A post going to under dash,over time with door opening and closing that harness has a tendency to break wires that may be the power to the switch or output to vent motors (inside the boot)

Relay Brian you need to find its location .

it may need to be reset.

SECTION 501-11: Glass, Frames and Mechanisms 2001 Explorer Sport/Sport-Trac Workshop Manual
GENERAL PROCEDURES Rear Window Motor Initialization CAUTION: Make sure that no obstructions are present in the power rear window system when carrying out this procedure.
NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.
NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.
NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
NOTE: Steps 7 and 9 require that the power rear window control switch be held in the closed position until the power rear window motor stalls the window in the upper header seal. Step 8 requires that the window control switch be momentarily turned to the open position.

1. Start with the ignition in the OFF position.

1. Turn the ignition to the ON position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the OFF position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the ON position. The power rear window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has entered initialized mode.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls in the upper header seal.

1. Momentarily rotate the power rear window control switch to the open position and release. The power rear window will carry out a one-touch down operation until the window stalls at the bottom of the travel stop designed into the window regulator.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls into the upper header seal. Once this operation is complete, the window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has been successfully initialized.

1. Verify correct operation of the power rear window by moving the window to the fully open, vent, then fully closed positions.

• The power rear window is inoperative (Explorer Sport Trac only)

• Circuitry.
• Battery Junction Box (BJB) fuse 3 (30A).
• Central Junction Box (CJB) fuse 20 (7.5A).

NOTE: The power rear window motor is not on the multiplex link. Any diagnosis and testing carried out on the power rear window will not involve the GEM module. NOTE: The reinitialization procedure must be carried out when repairs are performed on any part of the power rear window system including when the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.

First check fuse #7 and #16 in the passenger side dash fuse box, however I've seen this happen allot on this body-style of Odyssey's. Here's a quick check you can perform: Operate the rear vent window switch and listen for a 'click' in the rear of the van next to the vent window. This is the relay 'clicking'. If you hear the relay 'Click' you now know that your getting power in the circuit. This means that the vent motor is faulty. This is a common failure and they usually go out in pairs, so the other side maybe on its way out too. If you don't hear the 'click' than you'll have pin test the multiplex control circuit for a fault.
-hope this helps

Hi
