Suggest that you disconnect power to the car for several minutes. Reconnect the battery. The object is to reset the body electronics module.

If the computers in the modules get a glitch they can cause a drain. By cycling the power, disconnecting battery, they will reset to factory settings. Reported it can take up to 20 minutes for the circuits to drain before you can reset!.

the following web site does a great job of explaining all that is going on. What appears to be simple to troubleshoot is not so easy. He comments about delay before sleep are important. Testing after overnight may result in a different drain rate. Make sure that your battery meets specifications. In 2000 the drain rate may be relatively high and the reserve capacity of your battery low.

Hose is bad and probably leaked some fluid while driving. Low fluid level will explain loss of heat. Hose has fiber reinforcement, if bulging it is bad. Look close you will find a hole, maybe pin sized. Replace hose, refill system, bleed out air by ... run engine till warm with rad cap off, turn heat on high & gently to med rev engine while topping off fluid.

If you have the 4.0 engine, it is bolted to the right of the engine and under the power steering pump.

More than likely you probably have a faulty relay switch. Under the hood you will find a relay box with a removable top. Check the relay that runs the ignition fuel pump. It heats up and then breaks the electrical current and disables the vehicles ignition or fuel system and the vehicle shuts down until the relay cools and reengages.

Down under glove box. When it doesnt blow, rap on the motor with a wrench or hammer. if it tries to blow, or comes on, the blower is bad, replace it.

I had similar problem with my suzuki. It turned out to be a short in my wiring under hood. I found the short finally after having to replace the main computer (the short finally fried that). But with new computer it ran fine for awhile then when it shorted out again started smoking at the short

The likely culprit is your heater core. Simple test: Let you car warm up to Operating Temp. Run the heater. Under the hood on the fire wall you will see 2 black hoses conected to 2 aluminum lines about a 1/4 inch in size, feel both of these if they are not the same temp than you have a clog in the core and as a result no heat in car.

I had a similar problem. After changing just about every sensor under the hood, I finally fixed it by replacing the CCV valve and the vaccuum hose harness and all the hoses: http://jeep.off-road.com/jeep/article/articleDetail.jsp?id=257985 . It ran a little better and then I tightened down the throttlebody. That did the final trick. To be safe, I ended up changing the TB gasket. All cheap fixes after spending a few hundred dollars listening to Mighty Mopar Men.
