the Heater Control Pack
Originally written by
TB of MEG
is a common fault on Mk1 mondeos and some Mk2's although corrected
for later Mk2's.
heater resistor pack (also referred to as the resistor control pack)
control's the speed of the cabin fan. At positions 1 and 4 the pack
is bypassed, however when the select switch is in position 2 or
3 the excess power is directed through a resistor which enables
the fan to spin at a slower speed. If your fan isn't working when
on positions 2 and 3 (although sometimes 1 and 4 are also effected)
or if you have recently noticed a strange burning smell / smoke
coming from the passenger side footwell then chances are your control
pack is on the way out.

/ Crimping Equipment
No other equipment required
first thing to do is remove the glovebox and sound deadening foam
to gain access. To remove the glovebox open it and then tug sharply
toward the rear of the vehicle. The sound deadening may or may not
be in place and you may or may not have to remove it to get complete
the box removed you can see the heater resistor pack (Labeled A
above). The pack is screwed to the bulkhead with a single thorx
screw. Unscrew and withdraw the pack.
image shows the state of the existing pack and wiring connector.
You can clearly see where the wiring connector has burnt and melted
the plastic. Use the wire cutters to chop the old resistor pack
AND connector off. You should be aiming to cut about 4 CM back from
the old plug although if there is heat damage to the cable at this
point cut as far back as required.
you need to solder or crimp on the new wiring connector assembly.
Match each colour up and solder or crimp it to the existing cable.
Two points here, 1) Use an old rag when soldering to stop any unwanted
splashes of solder melting your carpet and 2) These cables carry
a significant amount of current. They must me soldered or crimped
into position ("chocolate" screw down boxes will also
do). Never just twist them together!!!
insulate each connection separately using as much tape as required
to ensure they never come into contact with each other. Connect
your new resistor pack to your new connector and reattach it to
