it is under the clove box behind the blower motor you will see it if you look its a black box
Blown fuse? Bad switch Bad fan motor? Bad fan relay?
Look in the fuse box below the glove box on the passenger side in the door pillar. You will find a fuse and a relay there. If that does not fix the blower fan issue, check the post in fixing the blower motor and resistor module.
Blower resistor pack broken?
The blower motor is failing and drawing too many amps.
easiest to pull blower motor then you can get at resistor, best to have a flexible extension (not a swivel) and you can access the bolts easier
I mean how do you disassemble the fan blower in a 1998 Jeep Grand Cherokee Laredo. how do you remove the blower fan from the car in the Grand Jeep Cherokee Laredo.
Replace the blower motor resistor block. It is located under the dash on the passenger side.
Bad Blower motor fuse Bad blower motor resistor Bad blower motor Bad switch Evaporator plugged- not allowing air flow
This happened on my wife's 2005 Jeep Grand Cherokee. She took it in to Chrysler for diagnostics and they found the blower motor resistor was bad and replaced it. part no# 5143127-AA Resistor Blower - 803502 $11.12 Electrical System Tech labor $149.21 It worked.
most grands with auto temp have a transistor style blower resistor. that resistor is known for sticking on when it fails. it is located under the passenger side of the dash, and is about the size of a deck of cards.
Resistor is located behind the blower motor assembly.
Running the blower on high for extended periods of time. The factory should do a recall do to faulty engineering.
