Default '96 Cherokee Blower Switch Wiring

The harness on my heater/AC blower switch got fried. I'm replacing it with individual wiring sections with 1/4" slide-on connectors.

The problem is: since the harness fried and fell apart, I have no clue which wire goes where.

Does anyone have a wiring schematic, or could look at their jeep and tell me?

The two columns are:
B
L
M
H
AC
I just don't know what the colors should be.

Thanks!

Looki There is a yellow/brown that goes to the resistor and blower switch. tan goes from resistor to blower switch, light blue blower switch to resistor, dark green blower switch to resistor, dark green from blower motor to resistor.

Thats probably doesn't help. I will look under the lower dash. I am guessing those letters are marked on the pigtail or something ???

Haha, yeah, doesn't quite make sense to me, but I appreciate it.

The letter markings are actually on the back of the switch itself (the rocker on the heat/AC panel), and would correspond to the slots in the harness.

The view in the bottom right of this picture is what corresponds to my letters above.

Awesome. Thanks for your help!

Any vehicle without heat in Iowa is useless in the winter.

I was looking at something different but this is what I see.

On the pigtail going in the box where the resistor is it looks like this.....


top left is light blue
upper middle is tan or brown
upper right is yellow black
lower is green.


LOL oh **** you need the wires behind the fan controls then huh ? Let me know before I start pulling my dash apart.

Haha, yeah, actually just behind the fan control switch. There are 5 contacts on the switch (I think there are actually only 4 wires there, though).

Yeah, no need to tear the dash apart.

Here is what I found on the diagrams. This is what it looks like with an educated guess

B-blower motor and dark green
L-low fan yellow brown
M-NO IDEA
H-heat black tan
AC-light green white

Thats what it looks like on the diagrams, It doesnt exactly say BLMHAC anywhere on them.

I was looking at the wire colors you gave and I didn't find exact matches, then I realized we might be talking about different wiring harnesses, lol.

The wire matchup I'm trying to find is right behind the switch. I've circled the spot in the attached picture. Sorry for not being more clear before.

Hello,

First post here, but I've been searching all over the 'net for the answer to this exact question. Were these the right connections? I have a '96 also, but I don't think my wire colors matched up quite the same as the ones posted here. Any help is GREATLY appreciated!!

Nope, it didn't work quite right. It powers it, but I'm pretty sure the voltages are not the correct ones.

Have you already replaced your blower motor resistor, down in the passenger footwell?
