My 1999 GMC yukon has recently blown the fuses that are for the brake lights, the tail lights and turn signal work fine. What could be the problem? Thanks

Does it blow the fuse whether you step on the brake or not? Use a testlite in place of fuse, if testlite comes on, your grounded somewhere. The teslite should control load on the circuit, but, it is still possible to heat up a circuit. Let us know.
