Cherokee ac blower fuse


Its not the fan motor. That would blow a different fuse. IT could be the compressor clutch that is shorting out.

If you can hear the fan motor increasing in speed but not flow then clean or replace the cabin air filter. instructions are in your owners manual

The fan works but my 2002 jeep grand cherokee wont blow heat what is wrong


It could be the thermostat or a plugged heater core. Check hoses going in to firewall after the vehicle has reached operating temperature for a drastic change in temperature if one hose is hot and the other cold or just warm your heater core could be plugged and would need to be flushed.

Fan motor blows air toward the grill


The rad fan should **** the air through the grill from front to back. Best of luck.
