Chevrolet Vectra 2007 99000 miles
Hi, ten days ago, I bought a Vectra CD 2.4 sedan 2007. Only some days after changing the oil and filters, it started happening that, when opening the front door, the window is lowered; but, when closing it, it does not raise to its closed position. The interior light remains turned on, as if there was an opened door. This is solved by pressing the central locking button from the inside. But it is evident that something is failing and I do not know what to do. I would appreciate your help because I do not even know whether to take it to the mechanic or the electrician. Thanks.
