93 22re Temp problem

[TotalChaosYota]

My '93 22re pickup is experiencing a problem with the temp gauge where it will not go past 1/4 from Cold when my engine is at normal operating temperature. At first I thought it was just an open thermostat; however, i replaced my thermostat and the problem persisted. I've heard the temp sensor can go bad, showing a low reading, but I discovered my temp gauge WILL show the correct reading (in the middle of the gauge) but this happens only when my heater is on? I thought I was on the right track on hunting this problem down, but this has kinda stumped me. Anyone else experiencing this same thing?

Thanks for any help.
