heating issues

ok I am no mechanic, but I know my way around my honda

here my situation
I have no heat in my car
I checked the wire/cable to the water valve and it snapped
I disconnected the wire from the water valve and tried to set it in "open" still no change
I unhooked the heater control unit ( dash mount )
I changed the water valve ( the original one is working fine )
checked all the hoses - no cracks of leaks and FULL of pressurized hot ass fluids
all my fluids are being heater properly but getting to the firewall then stopping there !!! ??
the rad is fine
full fluids
thermostat is fine

I worked on my ride with my buddy and he told me that on his wagon same situation with no heat but it was the water valve so I bought one and tried it ... not that
on his brother's car it was just the water valve

would it be my heater core acting up ?
how do I test it ?
what can I do to check it ?

I tried removing the whole dash and I can't seem to get to the unit ? do I have to go by the front ?
does the 40 amp fuse under the hood control the the heater core ? cause the fuse looks / seems fine ...

any suggestions ?

thanks for all the answers guys ...
I brought it to Honda Specialist and they found out that it was the trap cable that snapped

there are two cables - one that goes to the water valve ( manually adjustable if broken ) and another on the heater core to the traps to get the heat out and in the air ducts

the pieces were not expensive at all - I changed them both
water valve cable - heater control cable and trap cable were all together less then 15 $$

it was the labour that killed me - 2 hours at 70 $$
anyway I have heat now ...

now can anyone explain this....
i DO have heat.... eventually!!!
it takes prolly 20 minutes of driving and warming up, just to get WARM air. i can't even 'member the last time i had HOT air.

as opposed to my friends '97 'teg, where i'm sweating bullets after 5 minutes.

as cowgod asked...
"would it be my heater core acting up ?

ok check this out dude
manually open up your water valve
located on the firewall - little valve
if you have boiling rad fluid from your radiator all the way to the firewall and through the return piping then it's the internal trap door

I don't know any other way to explain other then the fact that you have something in your dash, that is stuck closed and your heat will NEVER come through until that is opened

I tried finding the unit and I never had success
I tried from the dash - remove the console / steering wheel / clusters / frame / glove box / airbag assembly

could not find the unit and was too pissed off to continue
just bring it to honda and pay the 50$ to inspect and the 50$ + to install a new one like me

it sounds always identical what happened to me - I had warm air for 1-2 months - then it became freezing air

It could also be low fluids. I have been having trouble with it some times getting hot, but not always. it seems that on the high way when Im really moving, that it gets hot, but just around town it doesnt.

How is the heater temp in RELATION to your engine temp. gauge?

If you temp. gauge stays really low on the scale, then the water is not getting hot. But if it is well into the "normal" area, then there is something up with the heating system.

There isn't a good way to check the heater core without blowing air through it. It is basically a second radiator in the dash that the fan pulls the hot air from.

the temp. gauge looks pretty normal. it gets to 1/3, maybe even 1/2 warm
