What do you mean by "doesn't have a heater control valve"?

Most vehicles have coolant running through the heater core constantly, there is no valve. How it usually works is with a door that blocks off the section that the heater core is in so that none of the air that is circulating through the box can come in contact with it.
Perhaps your problem is with the door not moving into the correct position so that the air passes through the A/C section rather than the heat section.

Sounds like the "blend door" is not working as straybullitt mentions. Is it cool when you first start the Jeep in the morning, then turns warm as the engine has been running for a few minutes?

Some vehicles (early Dodge Trucks) have this common problem. What year/model is your Jeep?

Try googling it (i.e. Jeep blows warm air with AC running) to see if it's a common problem, and to point you into a Jeep forum for further answers.
