Today, the vast majority of recent vehicles are fitted with power windows, and on Ford S-max models of recent years. It's very convenient, giving us the ability to open and close the windows just to ventilate the vehicle. It also remains an important role in terms of security, quite simply because we can close the windows of our Ford S-max quickly in case of danger. However here is the problem, with so many electric windows, necessarily arrive mechanical problems. It may take a bit of time but it is quite possible to do it yourself, with a minimum of patience. In this article we want to help you to find the fuses that power the windows of your Ford S-max in order to be able to replace them. We wrote a paragraph intended for their position and handling, then subsequently a second paragraph to other potential failures on your Ford S-max if it did not come from the fuses of the electric windows.find-fuse-glass-ford-s-max

Location of the window fuses of my Ford S-max

First, here's an important reminder about fuses and how they work. The value of the fuse is linked to the ability of the wires to withstand the current passing through them, it will jump and thus shut off the current so that the components of your Ford S-max do not burn. This means that if you want to put a fuse on your Ford S-max of greater resistance because the one in place blows each time after being placed, by improving the resistance of the fuse, you run the risk that it will not be used. more to nothing and that as a consequence it is the electronic components of your Ford S-max which burn out instead.
We advise you to carefully check the value of the current consumption required for the operation of your electric windows in the manual for your Ford S-max.
Your Ford S-max window regulator fuses (and all fuses as a rule) work as follows, the larger the wire, the lower its resistance, the more current will flow (ampere).
The resistance of a fuse is therefore directly related to its diameter, its length, its component (copper) and its insulation capacity. It will therefore burn when the heat created by the current is too great, which will stop the current.
On some models of Ford S-max, depending on the year, obviously if you still have manual windows you don't have fuses.
Otherwise, the manual for your Ford S-max will be able to help you find the exact position of the window regulator fuses. In this manual, you will find pages specially dedicated to the positions of the fuses, with the corresponding titles. So recognize those related to closing the windows of your Ford S-max.
There is a numbering of the window closing fuses so as to facilitate sorting by a reference to the numbered list in the manual. This will allow you to identify which fuse protects which circuit.
If ever they are not numbered, you can still take each fuse in your Ford S-max one by one and using a multimeter, make sure there is current through the fuse. The multimeter works by a simple principle, with a plus terminal and a minus terminal, it makes a current flow through a body. If you position the plus terminal on one side of the car radio fuse and the minus terminal on the other side, you will be able to check whether current can flow. If nothing passes, in this situation the fuse for the electric windows of your Ford S-max has blown.
If you do not have user manual, here is what you can do to find the electric window fuses on your Ford S-max. To the left of the steering wheel you will see a small hatch below, which you can remove by hand. Otherwise, they are located under the radio part of your Ford S-max in the center of the passenger compartment. As a last resort, they are located under the glove box, accessible by hand by unclipping a protective plastic cover.
To make it easier for you, we have also written an article specific to fuses and their handling on a Ford S-max, this can surely help you find the electric window fuse:

Other potential failures of the electric windows of your Ford S-max

If, however, the fault was not the window regulator fuses of your Ford S-max, we will try to list the other potential faults. First, you need the control panel where the opening buttons are located. They are usually located to your left or between the seats of your Ford S-max.
Remove it from its base in order to have access to the cables located below. If you don't see any unplugged, and nothing looks strange, remove the plastic part that protects the electrical circuit, and see if nothing is unsoldered. You can perform the same operation on the door of your Ford S-max, but it will require more patience and thoroughness, be patient.
From there you should have access to the motor that operates the opening of your windows, and therefore see what it looks like, if any cables are cut.
Important note: if when you press the window button on your Ford S-max, that you hear the sound of actuation, but that the windows do not move, then this indicates that the engine is running, that therefore the fuses are in place, but that it is the cables supposed to open the window that are cut. You will therefore have to dismantle your door to be able to reach them on your Ford S-max and thus repair them.
If, however, you hear a click of the engine cranking, nothing happens, and tapping on the door the window lowers / raises, then it's your engine who has a problem.
