Default Only Hi works with Heat/AC

Hey was wondering what I need to fix or replace, For the past year only the 'hi' setting works for my A/C and heat controls in my 94. I am going to be moving the panel down to the bottom slot soon and figured if I need to be behind there, now would be the best time. Any ideas?

usually its the blower motor resistor, when it burns out you only have high.

buy a new resistor, its available at any parts store. follow the wires from the blower motor back and they will plug into the resistor, the resistor will be mounted in the heater/ac air box

do just what I told you back in july to replace........the blower motor resistor and under the dash by the blower motor you should be able to see the connector going into it...unbolt.unscrew it and go to local parts store get a new one and install and enjoy all settings once again
