Reinitialise the Electric Windows

After the battery on your Jeep Compass (MP, 2017–present) has been disconnected or gone flat, the one-touch function on the windows often stops working — the glass only moves while you hold the switch. Re-initialising each window restores it in seconds, with no tools. It is a normal after-effect of losing 12 V power, not a fault with the motor or switch, and each door can be brought back to full auto operation from the driver’s seat.

When You Need This

Each window motor stores its fully-open and fully-closed positions, and that memory is wiped when the 12 V battery is disconnected or runs flat. The symptom is a window that won’t auto-close or auto-open on one press. The fix is a quick relearn from the switch.

How the Windows Work on the Compass

Every door window has its own motor and control module that counts the motor’s travel to learn where the glass reaches the top and the bottom of its run. Those two stored limits are what let a single tap send the window all the way up or down, and they also drive the anti-pinch protection, which reads the motor’s effort and reverses the glass if it meets resistance near the top. When 12 V power is lost — a jump-start, a battery swap, a pulled fuse — the module drops its stored positions and reverts to safe hold-to-move operation until it is shown the end-stops again.

Before You Start

• Sit inside with the door closed so the glass reaches its genuine top and bottom stops.
• Have the ignition on; running the engine is fine and keeps voltage steady during the relearn.
• Make sure the window channel is clear of ice, dirt or anything on the sill.
• Do one window at a time from its own switch so you don’t lose track.
• If the battery is weak, charge it first — a drop in voltage can interrupt the learn.

Re-initialising a Window

1. Pull and hold the window CLOSE switch until the window is fully closed, then hold for a further 2 seconds and release.
2. Press and hold the window OPEN switch until fully open, then hold for 2 seconds and release.
3. The window is initialised — check one-touch up and down both work.
4. Repeat for each window that lost its one-touch function.

If It Still Won’t Auto-Close

• Hold the switch past the end stop for the full 2 seconds — the motor must feel the limit to learn it.
• Check the glass runs freely — a sticky channel can stop the relearn completing.
• Run both directions again in order, close first then open, without rushing between them.
• Make sure the battery is healthy; a sagging 12 V supply can abort the learn part-way.
• Check the door’s window fuse if the glass is completely dead rather than just missing auto.
• Persistent fault? A window-module or switch issue can store a code — look it up on autodtcs.com.

What to Expect After

Once both limits are learned, one press runs the glass fully up or down and stops cleanly, and the anti-pinch reverse is active again. The calibration is stored and stays set through normal driving, so you should not need to repeat it unless the 12 V supply is cut once more.

Frequently Asked Questions

Why did my Compass windows stop auto-closing?

The one-touch memory is cleared when the battery is disconnected or goes flat. Without its learned top and bottom limits the module can’t judge the end of travel, so it only moves the glass while you hold the switch. The relearn shows it the stops again and restores auto up and down.

Do I need tools?

No. The whole procedure is done from the window switch inside the car — nothing to plug in, no diagnostic tool and no dash menu. It is a designed-in owner step. Only a genuine motor, regulator or switch fault would need a workshop, and that usually shows as a window failing even in hold-to-move mode.

How long do I hold the switch?

To the end stop, then a further 2 seconds, in both directions. Hold the CLOSE switch until the glass is fully up and keep holding two seconds past the stop, release, then hold OPEN until fully down and again two seconds past. That extra pause is what lets the module register each limit.

Do I have to do every window?

Only those that lost one-touch, though it’s quick to do them all after a battery job. Each window is re-taught individually from its own switch, so you can fix just the affected doors, or cycle the lot so nothing is left half-set after reconnecting the battery.

Why does the window bounce back down as it closes?

That is the anti-pinch protection reacting to resistance in the channel. During the relearn it can trip if the glass is dragging on a dry or dirty seal. Clean and lightly lubricate the run channel, check nothing is caught in the aperture, then hold the switch firmly through the full close so it can learn and hold the top.

Will I have to do this again?

Not in normal use. The learned positions are stored and survive everyday driving. You would only repeat the procedure after the 12 V battery is disconnected or goes flat again — for example a future battery replacement or electrical work. Otherwise it is a one-time fix that stays put.
