if norm.on the guage, its not the stat, check heater hoses for hot in and hot out under hood, if hot then heat is going threw heat core, and a vacuum controlled diverter is not moving under dash to flow air over hot core

Thank you, the diverter was indeed the problem. although the stat was sticking also. I replaced both and have great heat. Once again thank you!!
