Question
My defrost works, but my heater doesn't, blower motor working,but no heat coming from the front vents, also i can smell antifreeze in the cab.
 New water pump and thermostat, radiator flushed about 3 month ago.

Answer
HEY GILBERT,DOES THE DEFROST HAVE HEAT? IF IT DOES THEN YOUR CONTROL FOR YOUR VENTS HAS A VACUUM LEAK INSIDE OR OUTSIDE THE TRUCK. IF YOU HAVE NO HEAT AT ALL CHECK THE HEATER HOSES BEFORE THEY GO INSIDE THE TRUCK WHEN ITS WARMED UP. IF THEY ARE BOTH HOT THE HEATER CORE SHOULD GIVE OFF HEAT. IF ONE IS HOT AND ONE IS COLDER THEN IT MAY BE RESTRICTED. IF THE CORE IS HOT AND YOU HAVE A BLOWER,THEN IT HAS NO CHOICE BUT TO GIVE YOU HEAT. IF THE SYSTEM HAS AN AIR POCKET THEN IT USUALLY GOES TO THE HIGHEST POINT OF THE SYSTEM WHICH IS THE HEATER CORE. A BAD HEAD GASKET LEAKING COMPRESSION INTO THE SYSTEM CAN CAUSE THE AIR POCKET. THEY CAN TEST YOUR ANTIFREEZE FOR HYDROCARBONS AND LET YOU KNOW.I HOPE THIS HELPS,TIM.
