Planning on removing dash tomorrow to try and repair the speedometer with a replacement circuit board. Noticed the fan speed switch does not light at night but the temp switch does. What may the problem.......does it have a separate bulb and maybe a fiber optic line has fallen loose.......not sure what to look for .......any heads up.....

 

I bet it has another little bulb back there. Not sure though, probably can find out with an electrical Wiring Diagram :-)

 

I think my 94 Accord has a separate bulb. Dont quote me on this, because its been a while since I have pulled off my dash board.

 

Pulled the dash bezel out today and found the two switches and push button air functions unit one peice. On the back, right in the middle of the temp and speed switches , was a small bulb. I changed it out......but not sure it was bad......because I had light at the temp switch. Will check it and see if I made any improvement asap......
