jalexquijano Posted April 29 Share #1 Posted April 29 The low and hi headlights do work on my 72 240z however the blue light in my speedo is not working. Should i attempt to remove the speedo to change such blue led or should i check anything before? I already pulled both turn signal and combo switches cleaned all there connectors and still no blue light. Link to comment Share on other sites More sharing options...
Yarb Posted April 29 Share #2 Posted April 29 Did you happen to follow my suggestion on checking the harness with a meter along with the schematic? 2 Link to comment Share on other sites More sharing options...
jalexquijano Posted April 29 Author Share #3 Posted April 29 The schematic is very small and hard to read. Link to comment Share on other sites More sharing options...
Yarb Posted April 29 Share #4 Posted April 29 There are posts available here on the forum that are larger. Hopefully someone will chime in and point you in that direction. There is no easy fix if you can’t bug it out with a meter. 1 Link to comment Share on other sites More sharing options...
jalexquijano Posted April 29 Author Share #5 Posted April 29 Thanks Yarb. Its really hard to get inside that hole and replace the led. Link to comment Share on other sites More sharing options...
jalexquijano Posted April 30 Author Share #6 Posted April 30 whats the easiest way to get inside that speedometer and change that blue led? Link to comment Share on other sites More sharing options...
Yarb Posted April 30 Share #7 Posted April 30 Remove the tach pull it out and reach through the whole. A lot of work without testing the harness wiring IMO. 1 Link to comment Share on other sites More sharing options...
dutchzcarguy Posted April 30 Share #8 Posted April 30 Who told you it's a LED? If it was it would probably work.. as LED's (I'm talking about the good old led's that where around 40-50 years ago..) have a long lifespan. Normally there are candescent little lightbulbs in there. Someone with small hands and Patience can change them. maybe lying up side down in the car but it's in the blind doable. Link to comment Share on other sites More sharing options...

dutchzcarguy Posted May 1 Share #10 Posted May 1 Hihi.. yeah that's a L.E.D. (Light emiting diode) as it probably chinese junk, they die.. I got a bulb in my car and after 53 years it still works.. put the standard bulb inthere it will work for many many years.. I;m not against led's but just against cheap junk led's.. 😉 1 Link to comment Share on other sites More sharing options...
