Question about Cars & Trucks
The yellowish lights are to the left of the temp readouts, they go up and down. Turning it off does nothing. They just come back on. It's set for 68F, but it's running 76! Is this a purge of some sort? It's a rebuild, installed less than six months. All new guts, including 'mother board' and thermostat cause it kept blowing too hot, or not hot enough. Thought it was just the thermostat but my heater guy just replaced that whole board AND the thermostat! Was running like a top!

the problem is caused by the motor that operates the air temp blend door motor in the heating ducts, it blends air between AC and heater core tro give desired outlet temp.

you should have hot water on all rad. hoses when the motor is running at a norm. temp. the water is not going through the heater core like it should. you have cutoff valve bad low water are a stopped heater.try a hoter thermostat if none of the above are true.

dear friend-there is a couple of things you can do to find the problem,when the engine is cold remove the radiator cap start the engine then look inside to see if the water is circulating,all so look for bubbles in the water,if there is bubbles,you might have a blown head gasket,if there is circulation the water pump is ok,then get the engine up to working temp,then feel both the top and bottom radiator they should be the same temp,if not then the termostat is at fault

SOURCE: I have a 1993 Acura Ledgend.
first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure
