Hello All,
Volvo 740 1989 "G" reg.
I've got a problem with my Instrument illumination lights, sometimes they work but more often than not, they don't. Problem has been getting worse over a period of time.
All the other functions within the pack still work fine.
Fuse is ok, if it had been that it would have been consistently off.
Any thoughts?
Cheers, Richard
Try playing with the dimmer knob. Failing that, you can just connect the 2 coloured wires coming out the back of it together to remove the dimmer function and have the instrument lights on full bright all the time.
Have you checked the ground wire for the circuit?

Dimmer switchs, which are effectively a rheostats, go on the blink with age on 740's, intermittantly at first then either lock up at a set brightness level or just stop working altogether. There are occasionally posts on the topic. Mike F's solution is absolutely sensible, wire so on bright all the time. Switch from a breakers is pot luck especially given age and cost of replacement from Volvo?? worth it?
