A/C problem

I have a 2002 Ford Taurus SE. My problem is A/C and heat only work on the
highest speed setting. When I try the A/C on any speed but HI, I can still
hear the all the "clicks & hisses" of the compressor. HELP!!

Re: A/C problem

Sounds to me like the fan has gone bad on the lower speeds.

There's a pack of resistors used to slow the fan down for slower settings.
Chances are one or more of these are bad.

The following link may be of some help:

http://www.diynetwork.com/diy/ab_aut...278230,00.html

This particular episode was not directly about your problem but if you
scroll down to Fig. L - it will show you what the resistor looks like for a
blower motor. What happens is: When you set the switch [on your dashboard]
to the low or medium setting - the current to your blower motor passes
through this resistor and the blower motor doesn't run at full speed. If you
choose the high setting on your [dashboard] switch - the resistor doesn't
"slow" the current/voltage [so to speak] to the blower motor and you
experience your current situation. Typically the blower motor resistor is
located in 1. the engine compartment [usually near the firewall] or 2. in
the vehicle [usually under the dashboard].

With the Taurus I believe it's located under the dashboard on the passenger
side.
