2001 blazer heater core
looks like the plug that goes on top of your heater core box, controls the motor for the vents.

So I dont know what those connectors do but they're not connected, dash is all buttoned up and everything seems to be working fine, if anyone has any info at some point please chime in, thanks for your help earlier on too....
Ya I dont really remember unused connectors when I disassembled it all, know of anyone currently doing a core change? Maybe they could help, those connectors look pretty important to not be used.... I do have an aftermarket stereo that the truck came with, wonder if the one near the stereo was for the stock unit?
