Have 1998 V70 2.5 . 1. When closing the drivers door the lights do not always go out when inserting key. Have to bang the door shut if this occurs. I believe there is a microswitch in the door lock...does it have to be replaced or is there a tweeak I can do? 2. The tickover speed sometimes falls both when the aircon is on and when off. Falls to about 500 - 600rpm from a norm of 900. Car has throttle cable, etc not fly by wire! Is there an simple remedy for this? Many thanks....John Lowe UK
