I replaced the water pump last year and I still have no heat. I replaced the thermostat twice. The higher the rpm I get a trace of heat. The temp gauge in the dash barely moves. Tried bleeding air out of system, but do not have any. Heater hoses feel hot to the touch, so I am getting circulation. I thought maybe the heater core is plugged, but the temperature gauge not moving much has me wondering. Thanks for any help

If both heater hoses are hot, then chances are the blend door isn't opening allowing heat to enter the vehicle. However the fact that the temp gauge isn't moving (or getting warm), tells me the thermostat that you replaced is bad.
