Heater problem 1999 Mazda 626

Have checked the coolant. I have changed the thermostate. The radiator cap seems to be working properly. Both of the hoses exiting the fire wall are hot. I have seperated the AC coil duct enough to look up in to see if any thing is blocking the air flow. All looked clear from what I could see. The heater still blows cool air. I have read about a blend door that could be affecting the tempature. Any help would be fantastic

Under the dash board on the passenger side is where the heater core is located anything associated with the blend doorwould also be located there as well.

1996 mazda 626 overheats after shur off and sometimes driving. no smoke


sounds like a restricted radiator.. the thermostat has 2 x jobs to maintain the temperature and to restrict the flow-so by removing the thermostat you actually went backwards- meaning the coolant will flow to fast thru the radiator and will not have time to be cooled down prior to returning to the engine block. since your heater helps to cool it down my guess(educated) would be a restricted radiator..

Physically look in the radiator under the cap for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, have it boiled out, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Overheating


The first thing to check would be the coolant level, do this when engine is cool, if its full of coolant then my next step would be to make sure the fans are turning on, the most common thing would be a thermostant, you may want to start there and then see if it still overheats, if it does then take alook at the electric fans, if they are not turning on you may have a bad sensor that controls the fans to turn on at a certain temp,that part would be the coolant temp sensor, but start with the thermostant and checking the coolant level.

have you checked your

Check your coolant. If the coolant is low, you won't get heat in the cabin. Make sure that the fan is turning on as well. Check coolant sensors also. Good luck!
