On my 63 SS with factory air, I had trouble with the blower only operating on high speed. I purchased a new resistor for it from Old Car per recommendations and put it in. It still only ran on one speed.
My next thought was maybe the fan switch was bad so I found an NOS one on Ebay and got it. I just finished putting it in and there is no improvement.
So now I don't know what is the next thing to look for.
Anybody ever have this problem?

George

Look under the heater and air conditioning box for a fuse in a opaque holder. That fuse might be defective or there might be a break in the wire. Check it for power on one side. The only other thing that I could think of is a broke wire between the switch and the resistor. Without looking at the wiring diagram, it is going to be difficult. You will need to use an ohm meter between both points of the wire looking for a break if you can't find it visually. My experiences with electrical problems is that they are hard to find, and simple to fix. Many times it is just a bad connection because of a bad contact. Use your wifes emery board to clean up the male terminals if they look burned or dirty. The female terminals need to be pulled out of the plastic using a fine flat bladed screwdrive to release the holding tab from the front of the plastic, and then wire brushed with a soft brass wire brush.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

I have done everything suggested and nothing has worked. I give up. It will be what it is. I guess it's not that big a deal.

Thank you Junky,
George

It is a big deal to me, because you should be able to enjoy your car the way that it was designed. Has the factory installed been modified at all? We will work together to figure this out, or at least give it a good try.
Pull the carpet back at the headlight dimmer switch, and see if there is a 4th wire on the dimmer switch. If there is, remove this wire, and test your blower. Some of the cars have a yellow wire that drops the blower speed down when the bright headlights are illuminated.
