    OK, guys, its hot in NC and I need the rear AC...It was intermitten for awhile then just died in winter. OK, I am no rookie...I have restored many cars in my day from VW to old Caddys. The mystery is, where is the relay that powers the blower in the rear of a Suburban? There is power to the relays and they engage, you can hear them click with the knob, just no power to feed them or the blower. A friend has told me it is the high speed power relay...I have no idea as to where that is. There is no power on the rear power wire so a relay is somewhere to power it. Its not any relay in back, those merely activate the power that is not there for the blower. Any thoughts to where? My dog thanks you if you know where....Russ
