My equipment cluster lights in the dash don't work. These are the background ones that everyone seems to have changed to red (in the process, I have put in new 194B bulbs to change mine to blue to match the interior).
Everything else works--the aftermarket radio that the previous owner put in, the gauges, the headlights, tail lights, license plate lights, dome light, door buzzer, everything.
However, I don't have any lights so I can my speedometer at night.
I think my rheostat (dimmer) is dead. I'd love to bypass this, but every attempt has blown my tail light fuse. I've tried this about a dozen times, and have run out of fuses. Having the lights on constantly is no big thing. Or, having them controlled by a rocker switch would work too. I bought one, and can not wire it up without blowing the fuse.
There has to be a defective ground or a short, but all the wires leave the rehostat and duck into the dash, coming out at pin D of the equipment cluster.
I'm obviously an electricity noob. Please help me, in the most simple terms possible.
I'm planning on going to a junk yard this weekend to get a new rheostat, but something killed my old one (aftermarket stereo?) before I bought the truck, so I don't want to kill this one too.
If the rehostat is the issue, why can't I bypass with this a rocker switch without having it blow the fuse immediately?
