The heater only blows cold air, thermostat is new, the control valve, that allow hot water to heater core is ok (both upper and lower) lines from heater core, inside engine comparment are hot to the touch, but no hot air coming from vents
ARE BOTH HEATER CORE HOSES THE SAME TEMP?
ARE THEY (BOTH OR JUST ONE) HOT OR JUST WARM? CAN YOU FEEL AIR FROM ALL VENT POSITIONS, DASH, DEFROSTER AND FLOOR?

IS YOUR FRESH AIR DOOR OPEN?
IF IT IS OPEN, NOT ON RECIRULATE AND BOTH HEATER HOSES AT THE HEATER CORE ARE HOT, THEN I WOULD RECHECK AND MAKE SURE THE CONTROL VALVE IS OPENING AL THE WAY ALLOWING THE HOT WATER THROUGH THE HEATER CORE.
