i copied this off a volvo site Hope this helps

Check the wiring to the rear hatch. The cables break and cause a variety fo problems like yours. You will have to take the plastic cover off and expose the cables.

I have a 2001 volvo v70 wagon. My lower brake lights are not working but my 3rd (top) brake light works fine. I replaced the bulbs checked my brake light relay checked all fuses and ground wire and all seems to be fine, but the lower brake lights still doesn't work. I need Help!

It may have a seperate reservoir for the back wipers

I had a similar issue and started to notice other electrical failures along with the gas gauge. My rear doors would not lock and my rear wiper stopped working. I started pulling fuses and relays to see if this would reset, no go. But then I hit the jackjpot. In the rear electrical panel, below all the fuses and relays is a 2" x 2" black plastic square with a big screw in it.

Remove the screw and pull evenly on the black square. This seems to be a major electrical hub for the car. I reconnected and all 3 of my issues disappeared...I read somewhere that a fix might be to disconnect the battery for a few minutes, which I guess re-sets some relays and circuits, but I guess this did the same thing. Good luck.

Well, have you checked the fuse? Maybe stick another one (of the same size) in there anyway. If that's ok, then check the stop light switch. It'll be somewhere along the brake pedal linkage/ arm under the dash or under the hood around the linkage or master cylinder. Look around. You can short across the wires temporarily to see if they light up and then you'll know if that's it.

Fuel pump relay for V70 is behind the upper fuse box panel inside the engine compartment. Remove 4 Torx screws in fuse box housing, remove the panel, and voila, relays. Fuel pump relay is red and numbered 103
