Climate control speed knob

Hey guys, looking for some advise. The speed knob for the climate control has been giving me some troubles. It works on low, and one up from low, but the two fastest settings do nothing. If I move the knob slowly, in between the settings it finds the speed, but I have to hold it. My dad told me that the knob was not making a connection in back.

What do I need to fix this problem? Is it somewhat easy to install the new part? Is this something a somewhat novice could accomplish?

If so, what part do I need? What tools do I need? Any guidence is greatly appreciated. :thankyou:

I'm guessing you are talking about the fan speed control knob?

If so, there's two things you can do:
1) take the knob off (just pull...it slides off) and swap it for one the other two. The knob is plastic and is prone to breaking. Swapping it for one of the others will show if it is cracked and not able to move the fan speed controller. If this is not the case, try

2) Stop by your dealer and pick up a fan speed controller (should run about $21). Just by chance I replaced mine about 6 days ago. Its easy to do: 2 screws (phillips) to take the center console front off, 2 screws (phillips) to take the AC controller frame mount off, and 1 screw (8mm) on the back to take the controller off. Once you take the first two sets of screws off, pull the plug off the back of the controller, pull the three knobs off, take the front labeled bezel (that labels all the controls) off (be careful, mine was tight and wanted to break), remove the screw from the back, and slip the controller out. Once out, just reverse the process to put it back together with the new part.

In all if it is #1, it'll take about 37.5 seconds. If #2 it'll take maybe 10 mins.

Smile check the blower motor resistor

hey i have an 02 sahara. bought it used and only the lowest and highest setting worked on the fan speed controller. you might want to check the blower motor resistor. it cost me 26 beans at the dealer. it's located behind the glove box. now all four settings work.

mine wouldn't work on the lowest setting - dropped it by the dealer (was just under 36k at the time) and they swapped out the whole climate control panel.

My climate control panel went out as well. I only had the high setting for quite a while, but eventually it all went out this summer. Of course on the way to a wedding 4 hours away in 102+ degree heat!! I switched the panel out in about 10 minutes. The dealer had it in stock because "its a common problem with TJs" and it was less than 100 bucks including tax. Good luck!

I hope this is an active thread. I have a similar issue:

the first two fan settings don't work, and

the air deflector doesn't seem to work (i.e. only get air out of windsheild vent)

...are the two problems related, or two separate issues? If I bought an entire cc panel, would it fix both issues? Thoughts?

Oh yeah...is there a pdf illustration of how to disassemble the center dash panel?

screw behind ash tray. 2 screws up top (the windshield vent cover pops off with clips...under it there are 2 screws which hold the radio/CC surround on.)

remove those screws, and pull straight out on the surround.

Then the Climate control section will have a few small bolts holding it on to the dash.

switched and fused wire from the battery. simple, effective, tough. done and no more worrying about the resistor or the factory switch, tho you only have high speed. mines been like that for a long time.

Hey...glad to hear from you! I can get the two at the top, but my wife's seems to have a smoker delete package... there is no ashtray.... just a box or cover where the ashtray would normally go. Does it just pop out???

Hrmm...I wish I knew...mine has neither...P.O. threw the ashtray out.

but I wouldn't mind a cover for that area.

take a pic and post it on here if u can.

I'd probably try a flat blade between one of the edges and the surround...see what happens.

Hey, Mr.Car.... I got it. Seems there are only two at the top... the rest was held in place with clips. The third behind the ashtray is non-existent.

I ordered a new cc panel from the dealer... bout 100 bones. I am kinda throwing money at it, but my gut says to replace the whole panel. the blower motor switch is not working for the two lower settings... and... the air diverter is not changing position with the switch. I seems these are two entirely unrelated things... the only thing I think is in common is the panel itself. I guess we'll see. Thanx for the input... if you have any suggestions, they would be appreciated.

UPDATE: Well... got one of the two issues fixed. Apparently, the cc panel was not the problem. The fan selector didn't work on the two lowest settings... replaced the resistor... bam... all four settings work now.

The vent selector is still not working. I layed upside down and visually looked at what I am certain is the correct actuator... and it didn't move whilst I changed the switch. I moved it manually, and it pulled back to its orignal spot. I'm guessing its the actuator. Thoughts????

ps... I have a cc panel for sale =)

I am having similar problems with my blower motor .. ( I only have the high speed, nothing else) my dash and panel are out ( due to my "dead gauges" problem....which is now solved ) So i tested through a multi meter (continuity test) I guestmated that it wasn't the switch. What should I test for ...the blower motor, resistor? or what? Does anybody know if its possible it still could be the switch?

I would replace the resistor first... its cheap.... around $20... and can be replaced relatively easily. This fixed my blower problem. The blower itself, the resistor... just about all the cc parts are behind the glovebox/airbag on pass side

Now, if I could get the air diversion issue taken care of

MTabor-What year is your Jeep, and do you have a part number for the resistor? My 05 is having the same problem you had, just have the two highest fan speed settings. I was just about to buy the control panel too.

If it is just blowing out of the defrost vents....
Check your vacume lines going to the intake and manifold....Just blowing out of the defrost is the de-falt setting for the blower...almost always cause by a vacume leak.

Just stop by any jeep/dodge/chysler dealer....they keep them in stock VERY common issue. Should run you $18 to $22 for the resistor.

+1 any local dealership will have the parts.

If just high works think resistor.

if they randomly work, or you can push, pull pry the switch to make different speeds work its likely the switch.

Even if you buy both you'll be out 40 bucks.

The blower motor resistor SHOULD be behind the glovebox. You may need to remove the kick plate on the passenger side to access it. I have been working on my 2000 Wrangler the last couple days. Had to replace Radiator, Thermostat, Water Pump... Next I am replacing my blower motor resistor as well.

It's not behind it, it's really under it. Pull the glove box out and look straight down in the gap just below the glove box opening in the dash. You will see the connectou and the two bolts.

Speed 1...3 work, speed 4 does not?

What is the cause of blower speed 1....3 working and 4 not working. I think I bought a resistor prematurely.

I bought my 02 used. Only the 2 highest speeds worked until I got frustrated enough. Picked up the blower resistor at the stealership for 24 smackers. Works like a charm now. just in time for the cold weather to come!

Took apart the switch and there was melting around green wire. Wiggled and plugged back in and it now works... If it goes out again I will replace. This was a helpful link with pictures.
