I recently had to replace the fusebox in my 04 trailblazer due to the 46 hdm relay shorting and completely burning through the old box. Everything now works except the low beams. All relays and fuses work, connections are good, new bulbs, even tried a new bcm, and nothing. On a whim i touched the #5 pin on the hdm relay with a 12 volt test light while it was slightly lifted out of the fuse box, and the lights came on, and turned off andon with the switch. Any ideas where i go from here?
