Heat in my 92 cx is not working. Fluids are fine, but I am getting a code 10 & 14 which I haven't been able to fix. Need help soon. It's cold.
thanks

 

code 10 is IAT sensor - intake air temp
code 14 is IAC valve - idle air control valve

Niether of these should be causing your heat not to work. I would have a look at the heater core, and make sure everything is working ok. YOu also may want to have a look at the blower to see if its doing its job, and also check the little flap door that exposes the core to the passenger compartment. hope this helps

when you say it isnt working....does it not blow air? or does it blow, but blow cold air?

 

blows cold air
At first it's warm then its warm, then it gets cold.

check the heat coil

 

Where's that?

 

its not his thermostat, is it? that just came to mind but i dont remember how it works maybe someone can back me up or correct me on that. just a thought though

 

If it was the thermostat I think that one of the return hoses would not get warm, but they do. Very cold and I gotta turn on the ac to defrost. It sucks, help you guys...

It is the thermostat- replace that and you should be good to go.

 

The way you desribe it, in order for it to be a thermostat problem the thermostat would have to be stuck open. In that case the engine temp would drop dramatically when the car starts moving. My guess is that one of the cables that opens the doors in the heater case is broken or the valve that lets hot coolant into the heater core is not opening.

 

play with the temperature control and have someone look to make sure that valve is opening and closing.

 

ok I'll check all those things thanks

 

I have simular problem, however I DO NOT throw a code(s). My stock temp. gauge rarely works, after a long *** drive it will onyl go up 1/10 of the gauge, could I just have a faultly thermo? Please help, since were on the subject, thanks!

 

I think that is a faulty thermostat. It does that when it is stuck open.

 

Check on the firewall where the heater hoses run in to the heater core in the engine compartment. There is a cable that opens and closes a valve for the hot water to flow into the heater core. When you move the dash selector from cold to hot you should be able to see the cable opening and closing. You will probably need a friend to move the selector while you watch the cable.

 

Good info, thanks guys.
