    Is there a mixture control or water cutoff like in late model cars used to cut waterflow to the core when heater was off?

Heater in my 2002 jeep wont get hot unless going down the road and I have water in the floor on the pasenger side.

Sounds like you have a leak at the heater core and lack of heat usually means low water level in radiator. When engine is cold ,add some radiator "stop leak" top up the radiator, start the jeep but leave the cap off until the water is hot and you are sure radiator is full. Then tighten cap and drive or idle for about half hour or more. When you can afford it change out the heater core.

Car interior heater does not work when turned on to heat

You may find that the thermostat at the outlet of the radiator, input to the engine block, has failed open or has been removed. Some people remove the thermostat to stop the car from overheating.

With the thermostat removed, the engine will run cooler and there will be no heat available for the blower as the water used in the system bypasses the engine block where it would be normally heated.

Hope this helps?

do you have a "check engine" light on? A bad temp sensor would give a wrong reading. Do you get heat from your heater core? Also make sure you are getting a good flow from catalytic converter and muffler so you know they aren't plugged heating up engine temp. Also make sure all your heat shields are in tact. Are you using 50/50 mix or mostly water? Though in cold temps you normally want to use more antifreeze less water, I would try more water, less antifrezze.

2002 jeep wrangler OVER HEATING

Run it for a while and check the two heater hoses to the fire wall for the heater core. Turn the heat inside on low and floor. The hoses (when the jeep is hot) should be about the same temp. One will be slightly cooler than the other one. If this is not the case and one is much colder than the other you have a plugged heater core. Mark the cool hose let the jeep completely cool remove the cold hose and the hot hose use a garden hose to flush the core in direction of the cold side to hot side. If this is not it you have a air pocket in the system or your blend doors in the air box under your dash are broke.
