Volvo C70 - The drivers door window is not operating up or down though you can hear a brief noise as though something is happening. It will also not go down when using the all windows switch or when roof goes down either, the drivers side rear window will work fine with its own switch, but not when utilising the all windows switch.

I have replaced many of these, and it is a very difficult job. There are many steps you need to take as you are removing and re-installing the new window regulator that are crucial for a properly adjusted and operable window. Find someone who has experience replacing these or you will have wind and water leaks, and the door will not open or close like it should. Sorry to be a downer, but this is the reality of your situation.

Check to see if you have child protection locks on them if that is the case turn them off? Please rate my response Thank you very much

sounds like a missing tooth or stripped gear on the motor or moon gear on the regulator, the door will have to be taken apart and the regulator or motor replaced. If you can grab the top of the glass with your fingers GENTLY pull up while pressing the switch. it may catch another tooth and go up. (**Do not use pliers or any other tool to grab the glass**)

Hope this helps
