My dashboard lights will not work and I don't know if its the dimmer switch or just a fuse because the turn signals work and all the other lights come on but the actual light so you can see how fast your going and etc. are not turning on. Help????

If its just the light for the speedo and tach then its probably a bad bulb, if none of the lights come on in the dash, ie fuel, boost, temp then you should look into the rheostat (dimmer switch).

if non of the cluster lights and the corner lights on the bumper dont work but you headlights does , verify the light relay on the engine bay. good luck . Q
