The fan stop blowing air in the cab. - 1998 Jeep Grand Cherokee

sounds like the evap core id freezing up are you leaving it on recuit position to long?

there should be a filter under the panel where the wipers are, also is all of your fan switch setting working?

squirrel cage (from what i understand is the name) could be bad. its essentially the fan type blade looks kind of like a hamster wheel could have stopped rotating and isnt blowing the air into the cab. also could be your water pump. if the blade on the pump is bad then it could be circulating enough water to keep the truck cool but not enough pressure to send it to the heater core to generate the heat needed.

there is a cab air filter located under your hood, pass. side under the wiper area, but this should not be the problem if your loosing coolant, check your heater core, if your fan only works on low. check your blower resistor you can pick em up new for around 20 bucks. hope this helps and god bless.

Hello. I can assist you. The component that is failing you is the heater relay. You can change this yourself. Look in the manual for the fuse panel and in that diagram you will see the relay. Pull out the old one and replace it with a new one that is exactly the same, available at most any auto parts shop.

Blower motor resistor is most common ($20-$70) it controls the blower motor fan and speeds or fan relay fuse (usually under the hood) If it's not either then the blower itself is bad. You can pull the motor and apply 12volts to it to test, if it spins then the resistor.

Check the connector to the blower resistor, they tend to burn and destroy the resistor and the connector. Its located near the blower motor on the passenger side footwell.

check your blower motor

add some antifreeze to the radiator its low

TRY TAKING OUT A 1/4 POUND BUT FIRST MAKE SURE THE CONDENSER IS CLEAN USE SPRAY 9 OR A SPRAY CLEANER ON THE CON AND RAD AFTER CLEANER SITS FOR 5 MIN FLUSH WITH A GARDEN HOSE AND TRY THE AC IF STILL NOT RIGHT LET OUT A 1/4 POUND
