Answers :

Start your truck and warm it up to normal operating temp. Keep an eye on your temp gauge, when its at normal open the hood and locate the top hose off the radiator. With a rag or gloves grab the hose and squeeze it, your should be able to squeeze it with a lttile effort if not and the hose is real tight chances are your thermostat is sticking in wich case the temp gauge will be way above the norm. What i am thinking is this will not be the case, i think that your knob that regulates your heat has a broken cable. If so its a real pain in the **** to replace what i would do is locate your heater hoses(there will be 2) about 3 quarter,s of an inch round. Follow them to the point were there,s a valve inline with the cable there (by the firewall) attached or maybe broke there. This valve regulates your heat from the knob inside just move it (by hand or with pliers) to open it and you,ll get heat. Now this will have to be closed in the summer of course for the a/c to work. Hope this helps, sucks being cold! To change the thermostat just follow the top main radiator hos and with a half inch socket and ratchet remove the 2 bolts that hold it to the intake manifold pull it up and you,ll see the thermostat pull it out and replace it with a new 1 and a gasket (no permatex) replace the bolts start thr car warm it up and check for leaks.
