Question 97 Wrangler Blower Problem

I have seen the other threads about the blower only working on High. But almost everything points to the resistor.
So here's my problem...
My heater blows very hot, but only on the highest setting. Nothing blows on 1, 2, or 3. I replaced the blower resistor this weekend, but it didn't help the situation. I then removed the head unit from the dash to see if the switch looked burned out or anything. It doesn't.
What else do I need to look at? Do I need a whole new head unit? please help. Thanks

I replaced my switch first when I ran across this problem. My blower controls only worked on low and high I believe. I found the price for a new switch and it was less than twenty dollars so I opted to try this first. And it solved my problem. All settings for the blower work now and have not had any problems following. I have a 99 wrangler. Might be an option for you. Also, just by looking at my old switch I could not visibly see anything wrong with it.

OK, I have now replaced the switch as well with no difference. Does anyone have any ideas on this? Thanks

How closely did you examine the wiring harness between the switch and resistor pack? I have a '97 as well and my wiring was toast, I had to splice in new wiring at the same time I installed the new resistor pack.
