2000 Jeep Cherokee mileage: 90,000. I had a problem with the heater, it was only luke warm at best. I replaced the thermostat and still have the same problem. My temperature gauge also confirms that I am running much cooler than the 195 degree thermostat setting. I also partially blocked the radiator to see if I could get the temperature up, but that did nothing as well. Could it be a faulty thermostat or should I look elsewhere?

You may have a faulty thermostat or possibly incorrect gauge readings. Remove the thermostat and check it when it is cold to see that it is closed. Put the thermostat in a pan of hot water on a stove. The thermostat should be open when the water is near boiling. If the thermostat is okay, the temperature sensor may be your problem.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
