No Heat? What gives?

In my 03 Rubicon (5 speed) I went to turn on the heat last night and found out it wouldn't blow out and hot air!
I tried switching both knobs to various locations but couldn't seem to even get warm air to come out, all Cold A/c. Anyone ever had similar issues like this? Any help is appreciated!

sounds like a vaccum leak with the hoses that control where the air is comming from [hot/cold] and how fast.

Was it blowing out the defroster when you would turn the switch on? If so it's a vacuum problem as the previous poster commented.

Hey guys, thanks for your replies. I've been out of town and away from my baby for a while. Now I'm back and ready to start working on her.
I got in it today and it is only blowing air on the high setting. The first three settings don't work at all, no air, no nothing.
As for the original heat problem, there's no heat at all. Not on defrost or anything.
I've never had any similar problem so I'm open to any suggestions to what I can do to fix it.
Thanks guys

No fan speed issues is most likely a bad blower resistor. As far as the no heat, i would pull out your blend door actuator to make sure it's functioning ok.(located under dash passenger side). Pull it out and switch the temp control to see if it's working.

Yes bad blower resistor means only high speed fan.

If I can swap a blower motor resistor anyone can. I suggest removing the passenger side speaker so you can see better
