This is a little off subject because the race car is fine, but my Suburban isn't. Had something short out on my car trailer (probably a bulb) with the right turn signal or brakelight. This did blow a fuse on my fuse panel that powered the turn signals and reverse lights. The brakelight fuse is good however I don't have brakelights or turn signals on the Suburban any longer. All fuses are good and I've tested voltage on the fuse block and it's ok. I've replaced bulbs (3057's) and checked the flasher. It appears to have blown a fusable link somewhere on the vehicle but I'm not sure where it is. This is a '99 Suburban 1/2 ton with the full blown tow package installed. Anyone encounter this problem before and care to share what they did to solve it? I'm just trying to see if I can save myself a little time before I go on an all out scavenger hunt for this blown link. Any help would be appreciated.

Here is somthing you might want to look into, not sure if the chevys are this way but my 99 ford has separate fuses under the hood for the trailer lights. Did you check the manual for another fuse box?

when you look at that diagram see where your grounds are it sounds to me like it could be that if you have juice to the fuses and they are not blown it's not grounding to make the curcit. take a test light and put it in the light socket and ground it to the frame i'm willing to bet it will light if it does you have a ground off somewhere. at my old job we had that happen all the time on the semi trailers

Chevys have a master brake fuse (50 amp) MAXI Fuse under the hood in the fuse panel in front of the brake master. Look in there I believe it's a green fuse.
