only have air coming fro the defroster...nothing from the panel or floor on 1999 Jeep Grand Cherokee

the heat blend door works. the fan speeds work. I am looking to get air once again from any vent i put the selector knob to..no dual air controls...just a three knob manual in a 1999 jeep grand cherokee.
