Well the two circuits are not connected.
Are you getting power and a ground from the horn pad at the horn relay ?

Well the first question would be what does the temp gauge on the dash show after you have run the engine for 5 or 10 min ?
If the gauge is in the middle of the temp range the engine is getting hot and either the heater core is stopped up or you have a problem with the blend door under the dash.
If the temp gauge is staying around the cold mark the thermostat is not closing to warm up the engine.
I am assuming the radiator is full of coolant.

Your heater core is getting bad. It will gargle also when it gets air locked. Is your heater working fine? Check fluid level. When the heater core goes, you may slowly get wet feet. Hope this is helpful

Pull the heater control panel out of the dash and inspect the blower speed control switch, look for signs of a burnt connector to the switch, it will be discolored looking, if this is the case replace the switch and install a repair connector

your heater doesn't work any more

does the car over heat if it does it is a thermostat bad if not check your heater control valve if thats ood your heater core is bad

if you are getting power at the fan plug, it is possible that the recycled motor is bad.
