My heater core needs to be replaced in my 94 honda accord..I took my whole dash off except for the entire top piece..how do i get that off?

SOURCE: dash lights

possibility of a dimmer switch malfunction, did you check all the fuses under the dash and also under the hood. check thuroughly because you might have missed one.

And where your dimmer switch is, us a stanely knife on the corner and it should pop out.. peice of cake, the dimmer has 2 wires in it so you can take a volts tester to see if it gets current when your head lights are on. Alos if it is getting current only on 1 side you can bypass it for another test by just running a wire from both points.

Does your other dash peices light up like your ac controlls and your clock?
if so it might be part of the dash cluster has just burnt out, bulb wise and 3-4 screws around the cluster and it pulls out also. All hondas are like legos and they come apart Very simpley.

If it isnt either of those, then you might have a bad MFS witch is shot for multi function switch and it is the lever that controlls your lights. Its expensive to replace though and is a hastle to remove from the steering coloum to test.

Get yourself a volts, oms tester and check the dimmer switch 1st.
if thats alright then test with the wire.
if thats alright then check the back lights behind your cluster for burtn out bulbs,
and if all that looks good your down to the fuses might just look good, and the MFS

hope that narrows it down for you

Good Luck!

It's probably the valve in the cooling hose that lets coolant flow into your heater core. This is up against the firewall about 3/4 of the way down on the passenger side. When you switch the knob from warm to cool, you should be able to see the little "arm" on the hose move back and forth. You may need someone else to watch as you move the temperature knob back and forth.

Also, watch out for over heating (not due to the valve), because it could mean that you could need to replace your water pump and/or thermostat in the near future. If you haven't replaced your timing belt recently (or if you have) and didn't change the water pump at the same time (Honda recommended) Your water pump could be failing.

Odds are pretty good though that it's just where the cable connects to the valve. It may have rusted over time and stuck, or broke the end of the cable, or just need lubricating/bending back into place.

If this is not the case, then you may just have a clogged heater core and should have your coolant system thoroughally flushed in the near future. If none of these work, you may need to replace your heater core.

Drop me a line when you check these over and I'll see what I can come up with.

SOURCE: heating in my 95 honda accord

Here's my list! 1st-check coolant level, if it's low, u won't get heat. 2nd Is engine reaching operating temp within about 5 minutes or a little more? If it is running below the normal level, the thermostat may be stuck open, not allowing the car to reach operating temp, again, no heat. 3rd dash control not working to turn on heat. The heat control is vacuum operated, so if there is a leak or kink in the vac line, it won't work. (not too common). Many cars (I'll have to check on the 95 accord) have a heater control valve in the heater hose line under the hood near the firewall. Sometimes the valve just gets stuck in the closed position, so again, no heat as the hot coolant can't circulate into the heater core.4th plugged heater core. Corrosion, rust plugs up the heater core, coolant can't circulate, no heat.
Start w/ the easy cheap fixes, work your way down, let me know if u need more info. and how u make out.

If all the connection and power supplies to instrument cluster are ok,I suspect that the speedometer or instrument cluster is faulty but before you replace it, make sure the gear inside the transmission that drives the VSS is in good.

Yes clogged heater core may be the answer in your case .
