Just bought my Crossfire yesterday and this forum has been awesome. I was able to clear the check engine light in 15 seconds with a piece of sand paper to fix a ground wire. Then I moved on to the a/c -heater blower problem. This post is right on and I thought I would add a couple of poor man solutions. If the fan is not blowing, before buying a new fan motor or resistor you can try this. Take the fan assemble out completely. And try to turn the squirl cage, if it is hard to turn it may just be rust on the shaft that runs through the middle of the motor and squirl cage. I was able to shoot WD40 on both ends and tap /hit each end of the shaft to help loosen the rust. But the best trick is to take an electric drill and put it on the end of the shaft and run it up to speed for several minutes to disolve the rust on the shaft. Costs nothing to try. Also there are quite a few post on here for a clicking sound I believe that is caused by the brushes clicking on the contacts of the motor as it spins. If you look at the motor you will see two spring on the bottom of the motor, these press small magnets on to the contacts. As the magnet wears the edges get sharp and click as they cross the copper contacts. You could carefully pull the magnet back and carefully sand the sharp edge of the magnets and it would probably stop the clicking. I also discovered that if you plug in the resistor (three pronged connector backward, the fan runs on high even if the fan switch is not on. LOL it is a good reason not to be holding the squirl cage as you plug it in to test before installation because it will shoot out of your hand. Also if you need to access the fan switch itself on the center console you have to remove the radio first. I was able to do this by taking a couple of saw blades since they a thin and strong enough to fit in the slots I just ground them with a grinder to make them narrow enough to fit in the two tiny slots on the bottom corners of the radio. Make sure you grind off the teeth of the saw you are inserting or you could saw the slots wider if you are not careful. Push in about two inches, listen for the clip and then push toward the outsides of the car with the blades as you pull out and the radio will slide out. Then remove two screw behind the radio. You can pull the trim bezel out and down to gain access to the fan switch. It was a little scary because I didn't want to break it. But only two screw to release the trim.. Two more release the vent but not till after you remove the radio trim. I almost broke the vent trim tring to pop it loose before removing the bottom trim to gain access to the two additional screws the are hidden behind the top of the radio trim and can't be accessed until you remove the radio trim piece.
