2002 Crown Victoria automatic AC. A little over a month ago blower quit working. Doing a search I found most of the time when resistor goes out blower will work only on high, mine didn't work at all. I checked blower motor by running hot wire to it and blower is good. I bought a new resistor, installed it and blower worked good as it should. 3 days later it will only work on high. On auto it is higher than on normal ac. On auto or normal ac if I try to lower blower speed any it just quits. Any ideas what is wrong? Since high is faster on auto than on normal does that mean the resistor has 2 speeds working? Something else wrong?
