Question about 1998 Jeep Cherokee
I have a 1998 Jeep cherokee I6 motor. My problem is its winter here in Wisconsin. My heater only blows warm air.No hot air. Things I replaced and done. I have flushed radiator and heater core, replaced thermostat. Both hoses coming from core are warm to the touch. I get warm air from every position on the heater dial. I have read that there are some that get great heat and others only get warm heat. need advice on what to do next.
Pretty cold in Wisconsin. Bye the way its 18 degree out right now. WELLZE
The hoses from your heater core should be very hot to the touch. Check the hoses going to the core from the water pump. It should be very hot. The return hose should also be very hot. Now check the hoses going to the core. If they are not the same temp, then your heater control valve is not working correctly or the vacuum is not working. At any rate, locate the vacuum line going to the heater valve. Remove the silver bar on the valve from the plastic plunger arm. You will have heat all the time now if it was only a vacuum problem. You can fix it later when it's warmer out. BTW a 200* thermostat will make your heater even hotter.
