Thanks for your response!! It is working!!
When the fan stopped working, the first thing we did was change out all of the fuses, then the blower motor and then the resistor. When rechecking the fuses, one must have been loose, fan started working.
Replacing the blower motor and resistor is all good, old fan was not working, a mouse found its way in last spring and the fan always made a lot of noise since then. Replacing the resistor is good to; the Jeep has 293,000 miles on it.
Happy and warm in Upstate NY!!
