My temperature gauge is floating and it is causing for the light to come on on 2008 Dodge Avenger

Could this be a thermostat problem if so how much will it cost to get fixed.

Your thermostat if bad will either stay stuck open or closed. If it has been awhile since you changed your thermostat it would be advisable to do it anyway.
