There are two star-drive screws on each end of the resistor that need to be removed and the resistor will come out. There is a connector that has to be undone also. FYI - resistor is located underneath the glovebox near the firewall. If you purchase a $20 repair book at local parts store, it explains in detail. Pretty simple process unless...you have a short that causes the wiring and connector to overheat and ultimately melt. If this is the case you will have to replace the connector. The connector is part of a wiring harness that is available through a Jeep dealership only (resistor only available at dealership too). To replace the entire wire harness would take a trained mechanic several hours (VERY LABOR INTENSIVE). Pretty much impossible for anyone else - the wiring harness connects MULTIPLE devises and is intertwined throught the dash. I have never asked what it would cost for the dealership to do this but I bet you would be shocked. I'm guessing $600-1000 (or more). The wiring harness and the resistor are around $250 (if I remember correctly) just for the parts. This problem occurs for me once a year. I just splice the connector without replacing the entire wiring harness and everything works fine for about 1 year. I have been lucky enough to find the parts at junkyards - most it costs is $10-25 - although I have to frequently call or physically check for them. If anyone knows about a common problem that would cause the short in the first place, I would appreciate hearing about it!!! Good luck - It's a jeep thing...I don't understand. I hope you never have to replace the radiator...ridiculous. :)
Blower resistor pack broken?
The blower motor is failing and drawing too many amps.
it is under the clove box behind the blower motor you will see it if you look its a black box
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.
Blown fuse? Bad switch Bad fan motor? Bad fan relay?
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.
sometimes this is caused by the blower resistor heating up and shutting the circuit down, or it could be in the blower itself heating up and shutting down.
