A power window that stops working is a common car problem in the UAE, especially during or after the summer months when extreme heat puts electrical components under significant stress. Before paying for an expensive motor replacement, it helps to understand the common causes and how to narrow down the problem. Here is a practical troubleshooting guide for UAE drivers.
1. Check the Window Lock Button First
This is the most easily overlooked cause. Most cars have a window lock switch on the driver door panel that disables all passenger windows. If all passenger windows stopped working at the same time but the driver window still works, the lock button is the issue. Press and hold the lock button for a few seconds and test the windows again.
2. Check the Fuse
A blown fuse is one of the cheapest fixes for a non-working power window. The fuse box is usually located under the dashboard on the driver side or in the engine bay. Refer to your owner manual for the window fuse location. A blown fuse looks like a broken metal filament inside the small plastic casing. Replace a blown fuse with one of the same amperage. If the new fuse blows again quickly, there is an underlying wiring or motor problem that needs professional diagnosis.
3. Test the Window Switch
If the fuse is fine and the window lock is off, the window switch on the door panel may have failed. In UAE heat, switch contacts can oxidise or burn out. Some mechanics can test the switch with a multimeter. Alternatively, try using the master switch on the driver door for the affected window – if that works but the switch on the door itself does not, the individual switch has failed and needs replacement.
4. Listen for the Motor
Press the window button and listen carefully. If you hear a humming sound but the window does not move, the motor is likely working but the window regulator (the mechanical arm that moves the glass) has failed. If you hear nothing at all when pressing the button, the problem is likely electrical – a faulty switch, relay, or motor. If you hear grinding, the motor or regulator may be damaged.
5. Check for a Stuck Window
In UAE heat, window seals can expand and grip the glass tightly, especially if the window has been left in the same position for a long time. Try gently pushing the glass inward while pressing the button to free it. Also check that the window is not off its track inside the door – this is common when the car has received a side impact or when old weather seals deteriorate.
6. Motor or Regulator Failure
If all of the above checks fail, the window motor or regulator has likely failed. UAE summer heat accelerates motor burnout, particularly in cars that are regularly parked in direct sunlight. Window motor replacement costs AED 200 to AED 700 in the UAE; regulator replacement costs AED 150 to AED 500.
When to Visit a Garage
If the window is stuck open (a security and weather concern) or if you cannot identify the cause after basic checks, take the car to a garage promptly. A mechanic can diagnose the issue with a multimeter in 15 to 30 minutes, saving you from guessing and potentially ordering the wrong parts.
