My 1991 Previa has a ground short in the right rear brake light which caused "wig wag", I soldered the culprit ground wire to the bulb socket ground and this finally solved the problem of the brake light on the back rear not working when you step on the brake.
However now all the Dashboard illumination is totally gone, all the other instrument panel lights are fine and come on when you turn the key, but the Dash illumination is gone.
Might I have blown the dimmer wheel/switch? I have read here on the forum about Toyota "rheostats", does this refer to the dimmer wheel? When I had a problem with wig wag before I also had a problem with the cruise control not functioning, I guess I need to check if that's happening again.
Anyone ever have all their Previa dash lights fail when dealing with other electrical issues?
Thanks
Will
