Question about 1998 Jeep Cherokee
It does not have a problem when it is 40 degrees, but below that it blows mainly cold air. Also the temp gauge does not stay pointing straight up ( in the middle) unless I am at about 3000 RPMs.
Could be; thermostat, plugged heater coil, or maybe you're just low on coolant. If you have enough coolant, then change your thermostat. It costs like 4 bucks and should only take you about 15 minutes. Then, flush your heater core by disconnecting the two hoses and running water through one with a garden hose until water comes out the other, then reverse it after a minute or two. Do this a couple of times. You can also buy some flushing solution to do this with if it looks bad. I had the same problem and it turns out I was just low on coolant. I had a slow leak in my radiator and after I replaced it and had the right level of coolant I had nice toasty heat again.
