Why is my dash not lighting up?
If the dashboard isn’t lighting up at all, your car might have blown a fuse. Removing the old fuse and replacing it should get the lights working again. While the new fuse may do the trick, it could also indicate a deeper electrical problem.
Why do my dashboard lights dim when I turn on my headlights?
When dashboard lights go dim when the headlights are turned on, it’s usually because modern vehicles automatically adjust the dashboard brightness because of the current time of the day. Try adjusting your vehicle’s dimmer switch to restore the light levels to your desired brightness.
What causes the dashboard to go out?
A wiring short or malfunctioning accessory could cause such a surge. When too much current travels through a circuit, the fuse will blow, interrupting the connection before damage can occur. If your dashboard lights aren’t working, find the fuse associated with your dashboard lights and check inside.
What does it mean when dashboard lights dim?
The Cause. The most common cause of this problem is the dimmer switch. This switch or set of buttons allows you to make your dash lights dimmer or brighter to match your needs. The switch or buttons can sometimes be bumped, causing them to lower the brightness of the dash lights beyond what is comfortable.

What kind of instrument cluster does a Volvo 240 use?

Some of the pins in these images are noted with “Pos” or “Neg.” These notations refer to the circuit polarity going to the lamps related to those circuits.
When did Volvo stop using the M46 OD light?
The M46 was obsolete in all cars by 1991. If an M46 OD light is needed on this cluster, you may rework the OD arrow lamp in this cluster. Otherwise some custom work would need to be done to add a traditional OD lamp.
Which is a positive signal on a Volvo 240?
This signal is POSITIVE (12v), which completes the circuit for that bulb, since it already has a GROUND supplied by the circuit board, supplied through Pin 32/A. <<< Here’s PAGE 2 of the R-Sport cluster diagram.
