126 420 Sel 1986 Cold Feet
No heat driver's seat on floor...works perfectly passenger side
My wife feet keep warm and toasty...I get cold feet after an hour or so rolling

Is vent/duct possibly stuck? Or is vacuum controller that operates vent need replacement

all heat ac adjuctments work fine on car...temp adjust perfect

replaced mono valve last fall...much better heat now

I've seen heater unit outside of dash at parts supplier and understand how it works

any comments please????

thanks
