Flush heater core on 2000 grand cherokee - 2000 Jeep Grand Cherokee

SOURCE: 1996 jeep grand cherokee blower works but no heat

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Testimonial: "Thanks!!!"

Yes it's the heater core, It's a complicated diy job and unless you are an experienced mechanic you are going to need a good workshop manual for the job.

Best of luck.
