2000 Wrangler TJ - Heat Problem

Hey there everyone.

This is my girlfriends Jeep that I am writing about.
I am mechanically inclined and have fixed some stuff on my cars before but I need some troubleshooting help here first and foremost.

We're in Chicago and VERY luckily today and tomorrow we are having a "Heat wave". It is gonna be like 50 degrees today, and about 60 degrees tomorrow so I really want to work hard on getting this fixed by Friday if possible.

Her heater just stopped working yesterday.
The blower is not working at all.
The 10 amp fuse is fine.
There is no leaking antifreeze that I can see.

Now, I am baffled.
What should my next step be in troubleshooting this?

Thanks in advance.

You're going to have to check the fan and climate switch connectors (on the back of the switches) and check them for signs of melting. If they look o.k. you probably need a new fan speed switch. It's not difficult, do a search here for "fan switch" or "melted switch. Good luck.

Pokey Thank You.
I have dedicated the rest of today and tomorrow to this problem so I will get on that search now and troubleshoot that next.

I really appreciate your help.

I will report my findings back here as soon as I figure it out.

I have read about a dozen threads already and I am sure it has to be the switch

I went out to the jeep and couldnt figure out how to pull the switch or switch panel out of the dash.

Any help would be greatly appreciated.

Ok, I got the switches off and inspected the speed selector switch.
Weirdly enough the switch and the harness that connects to the switch looks perfect.

Here are a couple of pix I took...




Now I am back at square 1.

Anyone know what I should check next to figure out this heat not working problem?

Thanks in advance.
