SOURCE: blowing cold air
I had the same problem that I just fix by flushing the heater core out with a hose. take the two hoses off the fire wall and put the water to it and let flush. my heater is putting out 150 dg. F of hot air. I'm so excited! i will stay warm now.

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.

it may not be the blower motor. it may be the blower motor control module which use to be the resistor. it's located under the pas. side. remove the black coyer , 2 scaews above the pas. foot area. then remove the blach unit that has a purple wire going to the back of the motor on the right. price about 140 dollar with tax.
