DID YOU RECHECK LEVEL IN RADIATOR AGAIN?

USE CAUTION--REALLY HOT STUFF IS FOUND IN 'EM!

SOMETIMES YOU THINK IT'S FULL, THEN THE THERMOSTAT GETS TO TEMP AND OPENS, LETS THE AIR OUT OF THE ENGINE AND SUDDENLY THE RADIATOR IS LOW AGAIN

EXPLAIN THE "THERMOSTAT IS READING" THING?

ALSO FEEL THE HEATER HOSES AT THE FIREWALL---CAN YOU HOLD THEM OR IS IT REALLY UNCOMFORTABLE (HOT)?

YOUR TURN

Everything is full to where it needs to be. The thermostat is reading the temp inside the car as in its reading about 160-180 degrees, I just have no heat coming through my vents.

THE TEMPERATURE GAUGE IS SHOWING NORMAL.

WHAT ABOUT THEM 2 HOSES UNDER THE HOOD THAT ENTER THE FIREWALL SORTA IN FRONT OF THE HEATER BOX?

"ALSO FEEL THE HEATER HOSES AT THE FIREWALL---CAN YOU HOLD THEM OR IS IT REALLY UNCOMFORTABLE (HOT)?"

I CAN'T TELL FROM HERE.

IF BOTH HOSES ARE HOT--REAL HOT--CHANCES ARE THE RADIATOR JUICE IS CIRCULATING THRU IT JUST FINE

I KNOW LITTLE ABOUT YOUR CARS HVAC

I FEEL THAT YOU HAVE A DOOR INSIDE THE HEATER BOX THAT IS NOT MOVING TO ITS DESIRED POSITION (FOR SOME REASON)---THESE DOORS CAN BE MANUAL (CABLES), VACUUM OPERATED, OR ELECTRIC----THE LATER 2 USING SOME SORT OF MOTOR

DOES THE BLOWER RUN? CAN YOU HEAR IT? IF NOT, MAYBE YOU NEED TO INVESTIGATE IT 1ST

SO, A NO BRAINIER MIGHT BE LOOKING AT HVAC RELATED FUSES

LET ME KNOW HOW IT GOES
