The problems
1. - My '96 XJ doesnt heat up correctly. It sits at 105 degrees or fluctuates to the halfway point between that and 210 degrees. Most of the time it sits at 105 degrees.
2. - It doesnt blow hot air.
What Ive tried.
1. - I have replaced the thermostat which I verified as opening correctly by dropping it into a pot of boiling water.
2. - I replaced the heater control valve. When switching the HVAC controls I verified the diaphragm is opening and closing.
3. - I flushed the heater core with a garden hose both ways. After the coolant came out there was brown water for under 5 seconds. I flushed both ways.
4. - I verified the blend door is opening and closing fully with the cable as I move the HVAC from hot to cold and vice versa.
What Im trying tomorrow.
Replacing the fan clutch. I was told that if my fan clutch is bad that it would not let the motor fully warm up since the fan would be constantly spinning and that would result in my loss of heat as well.
Ideas? Opinions?
