No heat

Let me start off by saying I love my Jeep. Now, let me say that I don't love how much I have to repair it. Here's a rundown of the last three years since I've purchased my dream Jeep;

It's a 2000 Jeep Wrangler Sport 6cyl 4.0lit
No packages.
Stock Parts.

Repairs:
Exhaust (The entire exhaust)
Pumpkin seal
Ignition (Entire ignition)
Front and Rear Brakes
Power-steering case and lines (It cracked.)
Tires
Gas Tank
Entire front axle (oh yeah that was a whopping $2200)
Catalytic Converter (Another $1000 because its california emissions.)
Plus the 1-4 0-2 sensors
Driver side exterior door handle
front u-joints

. . . and now the heat/defrost doesn't work at all. At first it was that it would only work on high, but now it doesn't work at all. However, when I turn it to off, I do still here that small whistle (it sounds like someone is letting air out of a balloon. Its done that since I bought it.)

So, if anyone else has had this issue with their heat, or if you have an idea with what could be wrong, please help me!

Thanks so much!

*ps. I know it sounds like I'm resentful towards my jeep, but it is my dream truck. I wanted it since I was like five and while it's cost me more in repairs than what it is worth, I still love it. It's my baby and I will keep shelling out whatever it takes to keep it on the road. =D

I had that happen to me on an XJ I had. Very well could be the blower resistor. Only worked on high for a while then quit working completely, good news is it's a cheap fix if that's what it is.

Not working on any speed but High is almost certainly a blower resistor. If you have A/C it is located behind the kick panel in the passenger side footwell. It is a grey diamond shaped plastic with the connector. Unbolt it first, then disconnect the connector (easier than trying to take connector off first). You have to remove the red lock from the connector. A new resistor block will run you about $40. Very easy repair.

I am not sure why High would stop working, it does not go through the resistor block. Maybe you also blew the fuse....
