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.
