2003 Suburban.
I’m curious what the function of the smaller plug labeled “gray” on the back of the HVAC climate control does? My suburban was stolen and the wiring harness for this plug was cut. I have illumination and all the dials work but the blower doesn’t work. My assumption is this is for the blower? I will solder it up and check it, but won’t get to it for a few days. So I’m curious.
