heat issues

I have a 2002 tj that the blower only runs on high and the vent only goes to defrost.

Replace the fan's resistor pack which is a small module that gives all of the fan's lower speeds. It is bypassed for the fan's highest speed.

Poke your head under the driver side of the dash with a flash light look to the right and work the leaver for the vent and see if the vacuum controls are working

There's plastic levers that the vacuum actuators attach to that open and close the vent doors. These tend to break off, which would explain the vents not working. You can order new ones at Midwest Jeep Willys or something like that.

There is a tempature fuse that opens in the blower speed control (resistor pack). The tempature fuses are not easily replaced.

The speed controls are available at most every parts house, about $45
