Hello,
Heater is not putting out satisfactory heat. I hear gurgling noises under the dash on the passiger side. The thermastat is working fine.

Thank You,
Steve

If you hear that noise, chances are you are low on coolant and you hear the coolant entering the heater core when you accelerate.

Check the level and let me know what you find.
