Question about 2001 Mercury Grand Marquis
Installed a new themastat, flushed heater core.seems like a/c compressor is on when calling for heat, still blowing cold air
Check the both heater hose from the heater core to the block. In one of the hoses you may find a valve either vacuum or electric. Try to check for air bubble. You could check this by taking loose the top radiator hose.
