    I would say first thing to check is the fuses. I had the same issue and it was causing my car to overheat in the summer time so I had been w/out AC for 2yrs because the mechanic told me I needed a whole new radiator! $500 btw....So, my Dad checked it out and all it was was the fuse for the AC Fan!!!!! Good luck!

    mine did this.. i checked my volts going into the blower motor first, it was fluctuating,, which means the switch itself isnt working right.. they have adjustable resistors on the back of the panel for each button. it looks like a screw head (+), turn it either left or right, then back a little the opposite way so that the contacts on the resistor arent in the same place, if that doesnt do it, then you need to replace the climate control panel.
