jt, I thought I had the same problem that you described; however, it turned out to the what Paul stated it was.

As an FYI, swapping a TJ radiator is NOT tough, and as long as you're in there doing it, swapping any other older parts like the t-stat or water pump is a cheap, low-cost preventative maintenance item to do.
 
TJ water pumps are about 35.00 at Adv Auto and a thermostat is under 10.00 (gasket is usually extra). if you replace the water pump, be sure to see if the impeller has an "R" on it for reverse flow... order accordingly!
 
If hoses are older replace them too.

1997 TJ Heater Blower Problem by tjtime
Sep 29, 2009 (3:22 pm)
Reply
About every 10-15 months my heater blower loses 3 of it's 4 speeds. I take it to my shop and he replaces resistors or something and charges me $50.00. He mentioned that it had to do with the fact that the blower motor is basically a high speed motor giving high or speed 4, and resistors???? have to be incorporated into the circuit to produce the other 3 lower speeds. Can anyone tell me the full story on this 'fix' and describe exactly step-by-step what I have to obtain in parts and how to fix this thing without spending another $50? I was recently laid off and I now need the $50.00 myself. I know that the Power Distribution Center shows the "High Blower Relay" in position 11 and indicates it having a 40 AMP Orange Relay. Thanks.....

If it is blowing that much and resistors keep needing replacement, I'd suggest finding a local salvage yard and picking one up from a 97 (the newer versions operate differently and won't work in a 97). I'd also encourage you to pop apart that area of the dash and look for loose/frayed wires that may be causing the resistors to blow.
 
Probably replacing the unit is the easiest way to go. When I say replacement, I'm thinking the switches, not the motor itself. Perhaps Mac will jump in here and confirm or just laugh at me for being WAY off!

The shop the original poster is going to is fixing the problem, but not taking care of the cause.
While it could be a faulty switch, bad ground, or bad blower motor causing the resistor pack to burn out, the most common cause is water, damp crud or leaves settling on top of it.
 
The resistor sits at the bottom of the HVAC housing on the passenger side and if the Jeep is often parked under trees or the plenum drain is blocked (or a combination of the two), then moisture and debris can find its way into the housing.
A blocked condensate drain can also have the same effect, but the puddle on the passenger floor usually ensures it gets cleared before the resistor is affected.

i'm not mechanically inclined so pardon my many questions but, you're saying it may be leaking from the place where the lower radiator hose connects to the engine, not where the lower radiator hose connects to the radiator right? because it does seem to be leaking down from that vicinity. thanks guys, you are the shiznit.

What I'm saying is that the TJ radiator is made up of the main core with all the metal blades AND a plastic topper where the upper hose connects. That seam at the top is where the radiator tends to leak and run down the back side and LOOK like a lower hose leak.
 
In the pic below, you can see the upper part of the radiator and the seam.
 

 
A GREAT writeup on replacing it can be found here:
Stu Olson's Radiator Replacement Writeup. This is a very good site with lots of photos to detail mods and repairs for the TJ.

Electrical problems? by doot

I recently purchased a 97 wrangler. I have had to have the transmission rebuilt within 1 month of purchase. It is still throwing the " torque converter solenoid" code. Is also throwing a "throttle position sensor" code. Each time it does this the blinkers either start working or will discontinue working. None of these problems seem to occur at the same time. When it is showing the throttle sensor code it is idling around 1300 Rpm with seems very high.

Brake Light Issue 2000 Wrangler by HulkSm4sh

Greetings,
I've had great success here, hopefully it continues. My brake lights stopped working. I checked the fuses and the bulbs, they were all in good shape. All 3 break lights are out...left, right, and tire. My running lights work, as do my back up and turning lights. It seems to JUST be my brake lights. I went to the auto parts place to get a manual to help troubleshoot and they only had Haynes, which doesn't have electrical. Any help would be awesome. Also, does anyone know of a great Jeep manual for 2000 Wrangler??? I am having the worst luck finding one, but there are a million jeep nuts. This is my first Jeep, and I keep being told, "you will love it, but will learn how to fix it too". Thanks again and again.

Have you checked the brake light switch?
 
You can access the Factory Service Manual for a year for around $27 at: AllData.
