Hello and thanks in advance for your help. I have a 99 mountaineer
with climate control (just dial in the number and on Auto the
fan/cooling/heating control the temperature in the cockpit). It also
has controls for the temp and fan on the steering wheel. I went up
into the mountains and took the climate control system out of automatic
for the first time in a while yesterday to run the defroster and now
the fan won't run on any speed but Max. I think that perhaps there is
a second fan that comes on then so perhaps I have a fan that isn't
running at all. I checked the fuses and they all looked good but
didn't have time to put a meter on them yet. There is a fan relay that
I can replace. But I'm running out of ideas. Any experts out there
that can help me? Thanks, Jerry

I just had this same problem myself. There is a Fan Speed Controller
module in place of a blower motor resistor (only used on non auto
climate control). From my searches these seem very prone to failure. The
module sits in the blower motor housing and is relatively simple to
replace. This was the best price I found online @

Thanks. I'll give this a try this weekend. I love it when you can get
an answer this quick online. Hope I can return the favor someday.
