I had all my analog instrument panel gauges stop working after they did the state emissions test. I found the proper fuse in the fuse block located under the hood. Simply unplugged the fuse, noticed it was still good, and plugged the same fuse (10A) back in and all the gauges started working again. Guess it needed a reset atfer they plugged in for the emissions.

The Park Lamps and Instrument Panel illumination lamps are controlled by the lighting control module. The problem could be either the headlamp switch or the Lighting control module. Most likely, the head lamp switch.
The most likely cause of the brake lamps not working would be a failed Brake Pedal Position (BPP) switch. It could also be caused by the multifunction switch. To find out if it is the BPP, check for power at the BPP switch. One terminal has a Light Green and Red (LG/R) wire and the other has a Plain Light Green (LT GN) wire. The LG/R wire should be hot at all times. The LT GN wire should be hot only when the pedal is pressed down.
If there is no power at all, there is probably a blown fuse at fuse #10 (20 Amp) in the Central Junction Box (CJB) located uder the left side of the dash. If this fuse is blown, you have a short circuit between the CJB and the BPP switch.
If there is power only on the LG/R wire even with the pedal pressed, then replace the BPP switch.
If there is power on both sides of the BPP then check fuses #20 (7.5 Amp) and #22 (20 Amp) also locatedin the CJB.
If fuse #20 is blown, you have a short between the BPP and the Lighting Control Module. If fuse #22 is blown, you could have a short anywhere from the BPP through the Multifunction Switch all the way back to the brake lamps themselves.
The Brake lamps, Turn Signals, and Park Lamps all share the same ground, so if the Turn Signals are working, it is not likely a ground problem.

I had the same problem on my 2003 V70 with 138K miles. It is an easy fix. Simply remove your DIM by pulling the steering wheel all the way out and down (make sure you remove the key for all the next steps), remove trim around the cluster by pulling gently from the top and once the clips release, pull out the bottom. Next remove the top of the cover directly behind the steering wheel. Once you get those pieces off you will see (4) torx 25 screws on the four corners of the speedo. Remove screws and gently pull top of speedo towards you. Unplug the green connector on the top center of the speedo. I sent my speedo to Powls Speedo repair in Lancaster, PA. There are others such as BBA reman. Powls can either repair your speedo or as happened in my case, I had to get a "donor" speedo from eBay for $75. It was an 2002 S70 and I had it sent directly to Powls. They transfered the mileage info/programming stuff over to the "donor" speedo an sent both back to me. I went to the dealership and had them reprogram in my "donor" speedo uisng vadis. Install opposite of removal. Total costs with shipping, donor speedo and programming was just over $300. Good Luck!!
