Temp. Gauge Needle Not Working.

[rajesh ekambaram]

Hi all
I am new to this forum. My 94' 325i temp. gauge needle suddenly does not move beyond the Blue/Cold side, even after I drive the car for 20mins. After driving for 30+mins, it slightly moves out of the Blue side, but for away from the middle. There is no any visible sign of coolant leak or radiator crack. I also felt the upper radiator hose is warmer. I am not sure where the lower radiator hose is. The lower one that connects to one side of the thermostat and the upper hose to the side. I need help/suggestions. The car has 93Kmiles.

Any help is appreciated.

Thanks

The External temp. is in the upper 50's. I am in Nor. California.

K becuase recently when it was around 20-25 degrees my car took forever for the temperature needle to go up. Maybe the sensor for temperature is starting to go, or a loose connection?

I read couple of posts. There are talking about two sensor, one for radiator and one for external temp. Which one you are talking about.

If you turn on the heat in your car does it work? I had the same problem and my thermostat was out. Cost about $35 if i remember correctly. You can change it yourself but it can be a pain to bleed the radiator. I had my mechanic do it since i was having other work done. Now that I got a new thermostat my car heats up fine even when it is below freezing here.

For past two weeks, when i turn on the heater, it will blow extremely hot air even when i set the climate control to 64 deg. Now after this problem, it will blow air which is warm not hot, even when i set the temp to 80 deg.
