The windows in my 2014 Toyota HiLux won't go back up

The first thing to check would be the fuse or relay that protects the power-windows’ electrical circuit. Designed to protect wiring from an electrical spike or short-circuit, these fuses and relays can also fail for no apparent reason apart from old age.

If one window went south on its own, you’d be looking for a problem specific to that door, but since they all went out at the same time, you need to look for a fault a little deeper into the wiring. Which is where a blown fuse or dud relay comes into the reckoning.

The first job is to find the fuse or relay in question. The owner’s manual (which should still be living in the glove-box) will have a chapter that shows the location(s) of the fuse boxes in the vehicle. You might find there’s one under the dashboard near the steering column, and another under the bonnet. The same chapter in the handbook should also identify which fuse and relay does what, but this info should also be printed on the inside of the fuse-box cover.

Once you’ve identified the fuse or relay, you can check the fuse visually, or have an auto electrician check the relay for proper operation. If that component is the problem, a quick, simple and cheap replacement will restore the windows to full health.

If that doesn’t work, then an auto electrician is probably your next stop, as you could be searching for a broken wire or a failed switch-block or some other obscure fault.
