Heat not hot,ive tried everything!
Alright so i have been trying to figure out why the heat in my 96 cherokee isnt hot.I have flushed the heater core,tried replacing the heater control valve and it still wont get hot.I did notice though that the vacuum line that goes onto the heater valve has no vacuum to it.I disconnected the line from the vacuum canister and hooked it to the heater valve,which immediately opened,but the heat still didnt get any hotter with the valve working.I tried to find out where the little gray vacuum line goes,but it just enters the firewall.I figure the gray line goes to the heater core and has to attach to the valve since they work together.So i cant seem to figure out what is going on.Where does the line go? How do i get at it? Is the heater core bad? The thermostat? (runs at correct temp now though).Please help!

i took the heater control out and tried tracing the line,but i think i just saw wires behind it(was one gray wire/line).When u switch the heater control u can hear a little woosh of air,so i am guessing its still connected???
