No Heat in 1990 Jeep Cherokee

Any Ideas, I get air flow when the fan is on! The heat works, but barely! It is a 1990 jeep cherokee 4x4 4.0

    I have no air flow inside the cab from the heater on my 1983 jeep j-10. I have replaced the blower motor and the resistor,but still have no air flow. The door in the heater core box is in the correct position for heat and not cool air. If I open the door that is vacuum controlled on the passenger side duct work inside the cab I get airflow. I have no vacuum going to the selector switch on the dash. What do I need to do to fix the problem?

Well the first thing i would suggest is you take a look at its thermostat that could be over regulating hot air from flowing tothe heater if thats not got any major effect then have you been using an anti freeze formula for your engin coolant , because if not then it means the hot water pipes to your heater are blocked thank you.... if this was to benefit to you pease return the favour with a posetive rating

REPLACED BLOWER MOTOR CONTROL MODULE...Now blower is working but not very much air flowing out of vents! Fan speed is working...it heat and cools. but still not adequate air flow from the vents ..2000...

check your blower hoses to see if one or more have come loose or got redirected or the selector switch isn't functioning properly (is it blowing better on defrost as opposed to floor vents, or forward vents, etc.)
Good luck

Heater on 2000 jeep

most likely there is a door in the dash somewhere that controls the flow of the air. the actuator that controls the door for that side might be bad

I have a 89 jeep cherokee pioner, no heat!!

if the blower motor isnt working you would have no air flow till driveing,easy way to check it is to remove it connect the wires back and turn it on,but be carefull and hold on to it tight,as for removal its not to hard just need time.as to the location its on the passenger side firewall.

Everything in the center console not working! 1995 grand cheroke

Start by checking the fuses under the dash and under the hood. Could be a relay or a broken ground.
