Hello everybody i have a skoda octavia 2006 1.9 Tdi i have changed my battery as my old one has gone flat and now i have issues with the whole left side of my car on the passenger side front and rear after i changed my battery, the windows dont work the locks dont work and the wing mirror indicator and puddle light dont work but the speakers in the doors do work but this has ALL worked before i changed the battery, the right side drivers side front and rear all work normally only the left side has issues. Any advice would be perfect thank you.
