Hey guys, I wanted to start putting in led's for night time dash illumination. I think maybe there is something wrong with the wires that lead here because my dash lights don't light up at all. I checked the fuse and that's fine, so I'm not sure what the deal is. Turn signal bulbs work fine as does high beam so it's not the printed circuit board. The light for shifter and light for heater control and wiper controls also won't come on. Has anyone else had this problem?
ground wire maybe.It is easy to check with a volt meter, some of the lites you said lite use the same hot wire but the dash lits use there own ground thru the lite switch and the doom lite door switches,wipper washer switch to ground
^+1 All of the lights you describe are on a dimmable circuit.... Through the light switch. (Unless you happened to install every LED light on that circuit backwards... It's a power or ground problem with that circuit.) You checked the "INST LMP" fuse? (It's the short 3 AMP fuse, IIRC.) Did you just look at it or did you actually check for power to both sides of it with a 12V probe (or multi-meter) with the headlight switch "ON"? That fuse and circuit doesn't get power until the headlight switch is on. My guess.... Headlight switch or one of it's connections. Start with the probe on the fuse.. After that, Move to the headlight switch connections.
