Fixing the heater contol valve is very simple, however, what i might say could be totally different than what you need. I have a 1987 Jeep Cherokee Pioneer 4.0 and my heater control valve went bad and started leaking coolant like crazy. This is a very common problem with these older Jeeps. luckily, it's an easy fix. What you have to do is go to your local parts store (Schuck's/Checker/Krager, Napa, Auto Zone, O'Reilly, whatever) and ask for a heater control valve for your application (year, make, model). then it's just a matter of locating the valve (between the coolant reservoir and heater core) undoing a couple hose clamps, taking out the old one and putting in the new one. very simple. I hope this was helpful.
