Temperature guage running too cold

I have a '97 CRV (110 K miles) and recently noticed the temperature guage was running very low. After about a week, the guage never picks up off of the floor.

Coolant level is fine, however heat doesn't seem to be working to well, sometimes feel like it doesn't work at all (living in CT where temps are pretty low).

Is this just a case of me needing to change the thermostat? If so, can someone who's handy and willing to try it but not experience with working on cars do, or should I have a mechanic (or dealership) perform this?

Any help would be greatly appreciated!

Yes the problem is your thermostat. If you are not comfortable working on the car then take it to a shop. ;)

Thanks for confirming my diagnosis. Greatly appreciated!

sounds like the thermostat is stuck open... its an easy fix but id take it to a shop if your not sure about doing it..
