I bought a 02 limited a month or so ago. my heater control seems like there is something wrong. I needed the defrost this weekend and the front def wouldn't light up after hitting the ac on and off the switch lite up and I got front def. now the auto wont light up and sometimes I cant switch the inside air to outside air and the front def wont switch on again. anybody have problems with the limited heater controller? is there a sequence to turn the front defrost on? I am thinking I got a bad controller thanks for any help. I did search and didn't come up with anything but I am old and suck at searching.
