'03 Wrangler Blower Motor Resistor Help

Does anyone have a diagram or picture of where the blower motor resistor is exactly located behind the glove box of a Wrangler? For the life of me I can't seem to locate it. Is is up under the glovebox? Thanks.

Greg

FSM for 03:

The blower motor resistor is mounted to the bottom of the heater-AC housing on the passenger side of the vehicle under the instrument panel. It can be accessed for service by removing the instrument panel glovebox.

It also says it can't be serviced - must be replaced

The glove box has to come out.
If you have the factory under dash lights, remove the light under the glove box.
Two hex head screws hold the resistor assembly in place.
One of them is hard to reach.
Do not try to unplug the old resistor until you remove it.
Plug in the new resistor before installing it.
I have found it much easier to replace the resistor by removing the passenger door or at least unhooking the door strap and holding the door out of the way somehow.
Thanks.

Help!

How the heck do you pull the harness plug out from the resistor after unlocking the red tab?

I've tried to wiglle this thing free and it doesn't seem to budge. Any tips/pointers to help me pry this thing out before I totally lose my mind?

Thanks in advance.

should be the red clip which you have to pop backwards to unlock the red tab....then there should be a push in style disconnect that you have to push in and wiggle at the same time.

Thanks man. I'll look for the 'push-in' part of the disconnect.

Boy, it's tight in there. By the time I get this done it'll be spring and I won't need that darn blower.

Digging up an old thread here, but thanks for the info. My 1 and 2 speeds on the fan had stopped working. Did a little it of searching, found this thread... got a blower resistor for $17.99 +tax from Napa and not have 4 speeds on my blower again. I'm sure the stealership would have charged me $100+ for this easy fix. Well.. pretty easy... that thing is a pain in the *** to get to.

Anyways, thanks for the info!

On my 99 Wrangler. Knob position # 3 won't work . Put in new resistor with no results . Position 3 is my favorite , sometimes 2 isn't enough & 4 is to much . Anyone been thru this before have answers or help ? Hate to start tearing the dash apart ( again ) to check the switch itself but might be the problem . Is there relays involved that need to be checked ? Thanks from Canton Ohio .

There is a relay but it's for all 1,2,3, and 4 postions 1,2,3 are on the resistor speed pak while 4 is bypassed (high) if three is dead your switch is either melted due to the blower fan drawing too many amps, pull off center panel and pull out a/c control panel look at switch on back. If any wires or harness or metal tabs looks heated or melted, replace the cheap switch and go by a new blower fan motor. If you just replace the switch you will be doing this again and again until you replace the blower motor fan.
