1993 Jeep Cherokee blower/Heater Issue

When I turn the heat on it will sometimes start to blow but it almost sounds like the blower is clogged, it blows some air out and then gets louder and then the spinning stops and theres no more noise or hot air. The blower will sometimes put out a very small amount of hot air when on high. Usually after it will blow for a few seconds after sitting for a day and sometimes you can hear it starting up when you hit a bump. I checked the fuses and they are fine, could this be a short, or can the blower get clogged? What could this be, its cold in NJ and i need my heat! thanks for any help

Your blower motor could be "clogged" but I never saw one with enough debris in there to actually make one stop/ The cure for both is to remove the blower motor from the air box. if you find tons of leaves in there, clean them out. If the shaft on the motor has lots of side play, or will not run when connected hot to battery, replace it.

    Air box does not need to be removed to take out blower motor. Motor is in the engine bay on the firewall, passenger side. Sometimes there is a bunch of stuff you need to remove to get to it, but it's there! Its usually held on by 4 or 5 small (I think 5/16 screws) Once off, you can clean out the area inside (carefully... the a/c evaporator & heater core are in there. if you damage either one you will be removing heater box!!!)

Evaporator core is located behind the dash board, passenger side, inside heater box along with heater core and blower motor. It is basically a mini radiator that carries your Freon from your a.c. and your blower blows air across it, which is where your cold air conditioning comes through. Hope that helps explain a little.

My 1993 jeep Cherokee heater is not working right. While driving, it gets sort of warm but not hot and it doesn't blow the heat, it just gets warm. The blower doesn't work at all. Not with heat or on A/C....

It sounds like you have 2 separate problems. The lack of heat could be it needs a new thermostat. The blower problem is that either the blower switch is bad or there's a short somewhere in the wiring.

not sure on your cherokee but often there is a valve in the heater hose line just as the water enter the heater core .. the valve is controled by the the selection of heat or cool .. those valves frequently clog up and need replaced ... you might also have an air lock in your heater core .. if air is trapped in there then it doesnt want to come out and it occupies a portion of the heating surface .. you can take the top heater hose loose with the engine running but not hot .. that will blead off any air in the core .. it will also show you if you have a clog .. you should have lot of water flow thru there with the engine running .. you may also have a bad thermostat .. if that the case then the engine wont get up to temperature preventing the heater from working properly ..

Need to know location of heater blower in my 2000 jeep cherokee sport my heat gets warm but the fans not blowing

Down under glove box. When it doesnt blow, rap on the motor with a wrench or hammer. if it tries to blow, or comes on, the blower is bad, replace it.

1999 Jeep Grand Cherokee the heat is not working or blowing?

2 problems?
No blower motor: Blower motor resistor very common or motor itself or heater controls.
No heat: Start simple with check antifreeze level after vehicle has sat for a few hours. If that's OK then it could be thermostat, heater controls, blend doors, water pump, restriction in cooling system

Driving down the road and heater guit blowing out heat

Pretty sure I have answered this about a million times. Blower motor is on engine side of firewall on passenger side. You can run a hot lead to it to check if it's working! You did check fuse... Right?
