It has been in an accident with the front end where it became a salvage title, the car was repaired but not to the fullest, the radiator is in working condition and i can hear when the heat kicks on, but it takes a wile for the car to get hot, about 20-30 minutes to get hot, or if i go 60 it will get hot but when i slow down it gets cold, but after i do than it only takes 10 minutes for then heat to maintain its hotnes.

I do not know the history of your 94 civic as far as mileage, how well the car has been maintained or not maintained. Could be a block within one of your heater hoses, the valve that open and closes to allow the radiator fluid through your heater core to recirculate the water, or a block within your heater core from rust deposits and or lack of servicing your radiator fluid could cause a build-up of deposits. You might have an air lock within your cooling system" air pockets". Perhaps you can purge your coolant system to allow any air bubbles or pockets that may have entered the cooling system when adding coolant, replacing a radiator, or simply servicing the coolant system. Make sure you have the proper radiator cap to produce the proper amount of pressure with your cooling system. Check for any fluid leaks in your cooling system as well. This may allow air into your cooling sytem.

Overheating when I sit idle.

Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

Motor engine cooling fan only runs as engine temperature requires additional cooling.

1994 civic always humid inside , also poor defrost

not using the FRESH air vent on,
that is , avoid the RECIRC mode. in the heater.
RECIRC allows humidity to go to 100% (near rain)
or you have water leaks to the cab or both.
if fresh mode fails to happen, that means the heater dampers are stuck
this is covered in the FSM.
seen here.
see HVAC chapters

also check if you get full heat
one reason to not get full heat is the engine thermostat is bad.
180F is normal engine heat, easy to measure; ask.

Why does my 94 civic run for 5 mins and then lose power and die

There's no one answer here. Sounds like a component
failure due to heat or being energized for that 5 minutes.
Heard of cam shaft sensor causing such a problem, but
it will require professional help to located the problem.

The temperature of my 1993 honda civic it''s going up when i am driving it what could the problem be

Typical issue with the 92'-95' Civic. Thermostat is one possibility, yes. Another is that it overheated due to the thermostat or the fact that they have a very small radiator which tends to corrode and become increasingly less efficient, in time causing it to everheat and eventually cracking lengthwise away from the radiator cap along the (plastic) top of the radiator due to steam pressure on the inside of the rad. Inspect the fins on the radiator to ensure they are not turning green and corroding away, this will make a marked difference in your colling capability.

1994 Honda Civic LX\overheating within 2 mile drive

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.
