Interior problem
2004 Volvo V40 4 cyl Two Wheel Drive Automatic 89012 miles

My drivers side door handle wont open from the outside. I got the part from Volvo, but it is too expensive for them to repair it right now. I was going to try and do it myself. Is there a diagram/instructions available for this? I need to replace the entire door handle for a 2004 S40

THanks
