A/C blower issue

My 04 Rubicon a couple months ago would not blow air at the second fan selection, but did work on all the others. Than last week the third selection stopped working and all I have is high (the lowest is so low its hard to tell if anything is happening) which is fine in the south Louisiana summer, but i would like to fix it. I was talking to a dealer mechanic and he said that it could be a dozen issues. Really? What do you guys think?

ac issue

I was hardly getting any air out of any of the vents. it was all coming out of the top defrost vents. The vaccum hose had come of the motor, I popped the hose back on and everything was fine. If it is the vac hose you will here a whistling noise from the engine.

It's your resistor pack, it is behind glove box.

I had the problem with the vacuum hose coming off after I stripped the inside of the Jeep to apply "Second Skin" (similar to "Dyna Mat"). I must of knocked it loose. But, now its the blower speed that is the problem. It seems like I am loosing all control except high speed. Funny thing is that this was happening one speed at a time... I will check into the resistor pack as a problem child. Is there a way to check it other than replacing the item?

Picked up the part from the local Jeep dealer for $20. The top tech guy and parts man said this is the part that usually causes the symptoms I have. Will install this weekend and let yall know. Thanks again for the help.

I changed the resistor pack and that was indeed the problem. Thank for the answer to my problem.

I just went through the same thing last week and I swapped out all the fuses having to do with the AC/Heat system as well as the blower motor resistor too. FYI and For later on down the line Wranglers are prone to have the blower motor switch over heat and Melt into position.

I just picked this up in January of this year so I really can't answer that question. It just "seems" weak and I know that is a relative comparison. I'd like to improve the flow somehow.

Pull the blower motor out and see if it has anything built up on the blades. Check your ducts for blockage.
