Re: Vehicle heater problem
Check coolant color and condition. Long life OAT coolants turn into mud when neglected and the first sign of this is a heater not working or making gurgling sounds. Thermostat does not control heater as heater water is bypassed around a closed thermostat.
Since the your engine has to be speeded up to gain heat I would guess a plugged up heater core.
