The blower resistor has failed. Located behind glove box door.
If it works on some speeds and not others, the most likely problem is a defective Blower Motor Resistor Pack. It is located near the blower motor.

head lights Jeep Wrangler 2004. They don't work where should I start
I shouldn't, 1990 is a YJ and the 97 is a TJ.
No that will not work, 05 is a TJ and 92 is a YJ
They are both YJ's so it should be a good fit.
That should work, 2006 is the last year with that bolt pattern
