Rep Power: 0

Hello. My grandmother just gave me her 2000 Honda Civic LX. The driver side window and side mirror do not work as well as the driver side speakers. Also, the power locks will unlock as I am driving down the road. I have a remote to lock the car. I lock it every time I get out of the car. Sometimes when I come back to my car, I notice that the locks are unlocked. I did check the fuses in the fuse box. None of the fuses are blown. Does anyone have any suggestions as to what I should do? Thank you so much!
