Electrical problems with 2013 Great Wall X200

When a whole bunch of electrical and convenience items go on the blink all at once, the prime suspect is the vehicle’s body computer. This computer controls all the functions you’ve mentioned as well as plenty more including the entertainment and climate-control systems, the powered seats (if fitted) and even things like the seatbelt warning lights and buzzers.

An auto electrician is your best bet at this point, and chances are they’ll have seen this exact problem on similar models. Ultimately, you’ll probably need to replace the body computer, but you can try this trick first. Disconnect the car’s battery and leave it disconnected overnight. Next morning, hook it back up and see if the various functions have returned. Disconnecting the battery will sometimes force a reset to the factory settings and will return the body computer to normal service. It’s not a guarantee, but definitely worth a shot since it costs nothing to do.
