I just got a call from a buddy who has a 99 trailblazer and replaced the heater core, to do this you have to remove dast (stupidst thing ever)
but when he was all done there is a plug coming off the main box that has 4 wires on it brown blue orance and black, and says they are fairly thick wires. he said the rig runs and drives but it has no heater controls and no speedo a few other misc things not working, he canno9t find where it goes and does not remember unpluging it, now in this weather his wife and kid have no heat, anyone who knows these rigs know?
