There is three things that could be going on here, first the controls could be bad, secound it could be heater blend door acturator, and third it could be heater resister. i am thinking its the controls because you say it displays ER. on air controls witch i'am sure means error, if thats the case its not sending a signal to acturator to move the doors in the heater box, witch in turn will not let heat flow out into car. now i don't think its resister, witch only controls speeds of fan, sense you did not mention that in your question. it could be the acturator its a little electric motor on heater box that moves the doors in heater box, but it gets its signal from the controls on the dash. MONEY, acturator around $45.00, heater controls 150.00 to 200.00 resister around 20.00, and thats just parts this is just a guesstament just giving you an idea of the cost, thats if all three are bad witch i dought they are.

not sure on your cherokee but often there is a valve in the heater hose line just as the water enter the heater core .. the valve is controled by the the selection of heat or cool .. those valves frequently clog up and need replaced ... you might also have an air lock in your heater core .. if air is trapped in there then it doesnt want to come out and it occupies a portion of the heating surface .. you can take the top heater hose loose with the engine running but not hot .. that will blead off any air in the core .. it will also show you if you have a clog .. you should have lot of water flow thru there with the engine running .. you may also have a bad thermostat .. if that the case then the engine wont get up to temperature preventing the heater from working properly ..

Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)
