I just recently bought a 1998 V70 T5, very low miles (57,000). I can lock and unlock the divers and sometimes the front passenger door by using the key. To unlock the back doors I have to reach back and unlock them by hand. I can't unlock the back door by either front door switch or with key. I can roll up and down all windows from the driver's door switch with the exception of the front passenger window. I can roll down the front passenger window from the driver's door switch but I can not roll it back up. I can only roll up the front passenger window from the front passenger door switch.

Any help will be greatly appreciated. I'm sure I will have many more questions in the future.

Thanks
