Is a Muffler Heat Shield needed on a 2000 Jeep Cherokee Sport?

The heat shields on the Cherokee models are needed. The floor pans in the Cherokee models are thin and are penetrated by heat very easily. If you have driven one much, you will notice that the drivers and passengers front floor pans get quite warm from the engine heat. This is true with the muffler also. If it is not shielded the floor will get really hot and penetrate into the cab.

96 grand Cherokee heater work with key off?

The source of heat for the system is water/coolant from the radiator circulating through a heater core under the dash. Without the engine running and water circulating, there won't be any heat in the passenger compartment. There is residual heat after turning the engine off, but that won't last long. If the blower fan does not shut off, the resistor has failed.
