Question Jeep not blowing air at all? Checked a few common things. Take a look

So my second problem on my jeep is the fact that the blower does not blow. Not on cold, hot, low or high. I see the most common thing would be the resistor pack. I have a 2003 wrangler 4.0 and after reading some other write ups they stated to take out the battery and computer to get to blower and it wasn't there. I am assuming my blower is at the bottom of the passenger side where there's a switch with a small red tab?

Anyhow all fuses are ok. Here are some fuses I am missing and I don't know if its normal or not. My jeep has a 5 speed manual tranny.

Rad Fan 40a is missing ( i did replace with another 1 to test but didnt work, do i need this fuse?)

abs motor
abs valve
eatx
IOD storage

offroad (i believe for rubicons only)

Eatx Relay
ABS Relay

those things are missing from my jeep. On my interior fuse panel there is nothing missing or blown.

I personally am not too worried about the cold as it was 4 degrees yesterday and I was crusing just fine but I would definately like to fix it since my son likes to ride with me in the Jeep! Thanks in advance!

I checked the switches and they are fine, not melted.

you dont need all these ABS stuff if yours were not equipped with ABS.
also most stock Wranglers have clutch type radatior fan so no electrical system needed.
have you checked the blowermotor itself?

I'd check resistor pack, switch in dash (connections on back of HVAC controls are known to melt and cause issues), then blower motor...you can probably rule out resistor pack since the high setting I believe bypasses the resistor and is wired straight to the battery (well, basically straight to the battery).

Most likely the relay or switch, or possibly both. I'd run hot wire to your blower & verify its good. Here's a pic of the relay behind the glove box. If memory serves me right you should be able to jump the red & green wire to get to work. If it doesn't come on check your switch

Appreciate the help...I was unable to get it to work jumping the green and red wires. How can I check my switch? No connectors are melted...I also can't find a way to remove the blower. Like I said I am not very mechanically savvy but I consider myself a quick learner. I feel like I am so close to the issue but cannot figure it out.What would be the best way to run a hotwire to the blower? Where exactly is it located? Im pretty sure I found it, but it seems like a PITA to work with or remove?

So I finally got the blower off...so simple yet so complicated lol... Anyhow if I connected a positive and negative wire from the battery to the tabs pictured it should have turned on right? Because it didn't do anything. There was some mud stuck to it, so it probably fried?Click image for larger version

So I did buy a new blower installed and and works like a charm..only issue now is that air doesn't come out thru the front vents so I will research that!

Could be a vac leak or a faulty plug.

Hey all, I've been following this post because I have a similar problem (blower stopped working on all settings, 98 TJ) - I haven't had much time to address it yet. Yesterday the sun was shining and there were promises of 40F so I drove the Jeep. I hit a hefty bump and the blower started working on all settings. It worked for one more start up, then, when I left the office at the end of the day it didn't work.

Just curious, does that little hint point more in the direction of blower, switch, or resistor? Thanks! Josh

It sounds to me like a bad connection on one of the switches, fan speed switch or climate control switch. Probably melted. Check those first

not blowing any air

My 01 had the same problem looked at the controls could see nothing wrong so i took them apart and found the climet control switch was burning the contacts cleaned them up with a wire brush sqieezed them togather a little to make the connection tight and it has worked fine ever since

Thanks for all the tips. Took the dash off this weekend and pulled the control unit out. While jostling it the blower turned on and off. It would go off an on as I gently moved the unit around. I unplugged the harness to the blower switch, blew it out (no corrosion or burn) and plugged it back together. Working fine so far...knock on wood.

I just watched this the other day.

This guy does a pretty good job with the camera. It's broken down into three videos. The fan blower speed selector, the vacuum selector switch to change the direction the air flows and the blower motor itself. I pulled my dash off and unscrewed everything to see how easy it is. And, YES, it's super simple. Most of the time its just the fan speed selector. (about $20. I believe). I used to just take it in and pay for someone else to do the work.
It's no-longer under warranty and I get so much pleasure working on it. Therapy!!

Mine is not working on any speed. I jumped a wire from red to green and it blows. When I put relay back in, it dont work, I have tried 2 different relays and it still dont work unless there is a jump wire from green to red. Any reason why the wire works but the relays dont? Thanks.

I've had a similar issue and the control deck itself was the issue. Swapped it out and it worked like a charm. Although it's a $100+ part so I definitely recommend some more testing before jumping the gun on that.

It's also possible the relays have all been bad; it's rare, but it happens. Try swapping the relays with some known-good relays and see if they still operate that circuit normally.

That's for an extra fan on 2.5L

Cause the relays aren't working
