Question1999 Jeep Wrangler 4.0 The temperature selector knob rotates from cold to hot but the air temperature does not warm or change to hot when the heater is selected. I have verified that the AC compressor is disengaged when moving from AC to heater. I cannot seem to regulate the temperature, everything else selected works. Thank you.
