Heater not working - help

[wills_accord]

There are two cables that actually control heat/cooling, one runs from the console mix knob to the blower box and blocks or lets through air from the heater core. Then there is another that runs from the blower box out to a valve on the heater hose in the engine bay (it's down to the right of the fuel filter area, you will see the cable coming out of the firewall. Check and make sure that one isn't jammed shut, move it back and forth and maybe spray it down if its kinda stiff...I think thats the cable wills_accord is talking about also

I replaced both cables already. I opened the firewall valve manually and the blower box manually also but nothing. Just the same slightly warmer than outside temp air.

Can you tell if the heater core even heats up (is it even getting coolant flowing through)?

Good question . I dont hear it flowing, But opened the valve manually.

hmm, might have to pull the glove box and plastic cover off and feel it to see if it gets warm, i'm almost wondering if the hose is actually plugged up or if the heater core has some kind of deposit or something in there...

[Chaos325]

thats what its coming down to by elimanation. Either the core is clogged or that valve on the firewall. I'm getting tried of driving with the a/c on during rain and buying antifreeze figuring it out. Damn antifreeze is $8XX plus tax around here!

dealer found out that the core is clogged...looks like they gonna rape me on labor...

what could it be clogged with?

(i wish the heater in the house would work... i'm freezing here.)

[Chaos325]

pepper. damn autobody guy put it in there to stop leaking antifreeze

Look under the glovebox near the console there is a a lever with a cable connected to it when you turn your knob make sure it is opening and closing.

I have a similiar problem where the knob turns but it does not open the vent to change from hot to cold. I do it manually under the glovebox.

Also, check from under the hood...there's a latch that opens a door to let coolant through the heater core I'm guessing. Somehow mine got detatched and I didn't have heat either. I reconnected it and now my life is warm and toasty.

Okay, I have the heater core flushed today. Works like a jet engine!!!
