MAYBE THE HEATER CORE IS STOPPED UP?

IF THE HEATER CORE ***IS NOT*** THE ISSUE, WHEN AT OPERATING TEMPERATURE, BOTH HEATER HOSES WILL PROBABLY BE PRETTY DARN HOT!

NOT FAMILIAR WITH YOUR CAR/ I CANNOT ACCESS ANY INFO EITHER

CAN YOU TAKE THE HEATER HOSES LOOSE ON THE ENGINE SIDE AND SHOOT GARDEN HOSE WATER THRU THEM (ALTERNATING HOSES) TO CLEAN OUT THE HEATER CORE?

IS THERE A VALVE IN THE HEATER HOSE LINE, WHICH OPENS WHEN HEAT IS DESIRED, CLOSES WHEN IT'S NOT? IF SO, MAYBE IT'S NOT WORKING

AS FAR AS THE "GATES" (BLEND DOORS) MAYBE THE IS ONE YOU DON'T KNOW ABOUT, MAYBE IT'S JUST PLAIN STUCK/ ACTUATOR MOTOR INOPERABLE/ IF IT'S VACUUM ACTUATED, MAYBE A VACUUM LINE IS CRACKED/ LOOSE.

CAN YOU GET A DIAGRAM FROM A REPAIR MANUAL/ ONLINE (MAYBE A FORUM DEALING SPECIFICALLY WITH YOUR VEHICLE) OR EVEN "YOU TUBE", ANYTHING THAT MIGHT SHOW YOU AN EXPLODED VIEW OF YOUR HVAC SYSTEM THAT MIGHT GUIDE YOU TO A SOLUTION

SORRY, THAT I COULD NOT HELP MORE

I HOPE THIS DOES HELPS YOU SOMEHOW

LEMME KNOW HOW THINGS TURN OUT!
