Your problem is the air temp control blend door actuator is defective and not controlling temp u set. to change/access this part the dash assembly must be removed from the car.

SOURCE: heater /ac

i had this exact same problem with my 98 explorer. your blend actuator (blend doors) are not morking. these are on the passenger side under the dash. getting to them will be dificult, but it can be done. you will need to take apart the heater box, to fix them. (the big black box under the dash).

SOURCE: When driving, heater blows warm air. When idling, cold air.

It sounds to me like you have a plugged heater core, or one that is beginning to plug. With the engine running, carefully feel the two hoses that lead from the engine into the heater core in the firewall. If one of those hoses is colder than the other one then you heater core needs to be replaced. This involves removing a bunch of stuff under the dash. Sometimes it's pretty easy and sometimes not. Start by removing the glove box and you should be able to see the plastic housing for the heater core.
