A/C Only works on HIGH FAN setting?

I think I forgot to mention it's a 2002 year automobile, thanks again

Bad blower motor resistor pack. I haven't replaced one on a Taurus, but the few I have replaced haven't been expensive at all.

So it's fairly easy for a layman to replace?

I've replaced one on an Isuzu pickup that was a piece of cake, a Crown Vic that was a moderate pain, and an Escort that left me sore for three days. If I were to have to do it again, I'd pay someone else to do it.

ok, thanks for infoi

thanks for fast accurate info.

I would check to see if there is a recall on this. I had a recall on my blower resister on a Contour. The reason why Ford might make a recall is that this is a safety issue.

Is the air coming out of all vents, or just the defrost ones?

Could the problem be the climate control vacuum pump?

Everything works but only at the HIGH blowing setting.

Can't say for sure in your exact car but, in all the Fords I have worked with, the blower high speed circuit does not pass thru the resistor block. It will usually run on high if nothing else. It is likely that you have either a bad resistor or a bad control switch. The resistor is much cheaper and easier to replace. Also some of those circuits use a fuse on the lower speeds while running the high speed thru a relay. The fuse is occasionally replaced with and auto resetting thermal circuit breaker.
