I HAVE A 1994. THE HEATER DOES NOT WORK BELOW 3000 RPMS. THE FAN WORKS FINE BUT BELOW THAT BENCHMARK IT BLOWS COLD AIR. WHATS WRONG?

1993 Toyota Previa • 15,000 miles

The heater works fine on the highway. If I drive above 3000 rpms it works fine. Around town it obviously does not work well. Does OK in first and second gear if I keep the rpms up.

Check the coolant level first. If it's low it won't heat. Then check to see if cablesare opening doors and for a faulty water pump.
