If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired. Heater Housing
The heater housing is usually under the dash and must be removed to gain access to the heater core.
Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
The heater housing is disassembled to get to the heater core.
Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
Remove the heater coolant hoses.
Remove the cable and/or vacuum control lines (if equipped).
Remove the heater core securing brackets and/or clamps.
Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.

When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.
Could be a heater core plugged or improper adjustment on the heat exchanger cable. Turn your heater on high and go under the hood and feel the two hoses on the passenger side coming out of the firewall. See if both hoses are hot when the engine is at operating temperature. If they are both hot then there is probably a problem with the cable adjustment or heat exchanger door not functioning right. If only one hose it hot then your heater core is plugged which means changing the heater core or you can take it to a radiator repair facility and they can hook up to your vehicle and can sometimes clean your heater core. We have had success at doing a bunch of plugged heater cores this way. Worked in most all cases.
Your blower resistor may be wearing out or corrosion setting in. The part is cheap and you can probably replace it. This link shows where an 01 is located. Yours may be in the same spot on on the engine bay side of the passenger firewall. Check with your auto parts store also for location.
It's coinsidental.You have a bad motor on the heater box,very common.You can't replace it yourself either. The motor has to be programmed in the body computer. Physically you can replace it but you need to get it calibrated & programmed.
The problem that has caused this cold air only issue is the Air Temerture Control Blend Door Actuator Motor, this motor is on the ouside of the air duct about center of the dash, in order to access and replace it u must remove the entire dash assembly. this is about a 12-15 hour job.
First check fuse panel for burned fuse, if all o.k., Take a look up under passenger side dash, it's usually a common spot.When you find it, locate wires going into it & probe with 12vdc test light for power with key on & fan in run position. If light comes on by probing one of the wires, your fan motor is shot, if nothing at either wire, start back tracking for relay & switch malfunction.
