My '96 Contour temp gauge doesn't move. I know I've seen this posted two other times with everyone saying its the sender. However, in my case, it does move. Every few weeks I will notice it about 1/4 the way up for a while. Also turning on the heater and setting it to the panel when first starting the car I notice the gradual increase in temp as it warms up, not the sudden change as a thermostat opens up. So I'm thinking I need a new thermostat instead of a sender. Comments please.

Air conditioner controls should not have any noticeable affect on normal operating temp.

Your symptoms indicate a thermostat that has failed in the open position.

Steve - Didn't use the air. I turned on the heat through the panel vents before the car was warm. I think you're right about the "failed in the open position" for the thrmostat though.

SO go ahead and replace the thermostat. They are wicked cheap. Just be sure to get the gasket at the same time.
