heater doesnt work, halp!

[UnderPaidSlave]

im guessing the heater core is clogged, i hope not since its in the dash somewhere..... any insight on anything else that could cause this, car runs at normal temp's.. heater kinda works but not like it should.. anyone changed a heater core? was it hard?

check your thermostat first, second your heater control valve cable to make sure its opening the valve.

how do I manipulate the cable?

I know the thermostat is good, guess I figure out the control valve thing..

I've changed a heater core on a 94 Cutlass, yesterday I completely rebuilt a front end for a 92 Accord. Guess which I'd rather do again? (Hint: Accord)

Did you put any "stop leak" crap in your radiator? If so, then that would be what clogged your heater core (if that's the issue.) Very often, that's the cause of a clogged heater core. Another cause would be extended use of unpurified tap water as coolant (deposits build up and cause clogs... straight water should never be run as coolant, and only filtered water should ever be used if mixed with a concentrated antifreeze coolant.)

do the fans come on when you turn the knob ? if so , i'd say the heater core is shot . i have seen cases were the core was bad but not leaking.( stopped up ) . if its stopped up it will run hot because its not flowing properly. drain and reflush the system .

As stated above, check the heater control valve, I think it should be turned toward the firewall.

are you talking about the fans that blow the hot air? yeah. or cool air i guess.. um whats the best way to flush out your coolant system?

[stretch JDM]

you can buy a flush kit from most part stores. then drain the radiator , it has a plug on the bottom .

Don't forget to try swapping out your main control unit on your dash with all the temperature knobs AC etc, that ended up being my issue. the board that controlled whether or not to send hot air was fried

im having the same problem exept mine blows regular air, not warm not hot.. they told me it could be a fuse "12"

So, my headlight lens was broken sometime lastnight, how the hell do I remove the headlight housing?

if you were to create a new thread for yourself you would get a lot of more replies, but to answer your question is easier to get another headlight than changing your lense....
