Air con /heater problem

The fan fault is failure of the fan speed resistor pack; Google will give you the info you need if you fancy replacing it yourself. Note that failure can be caused by not changing the cabin filter at the proper intervals.

The a/c won't work without the fan running.

Thanks , i have a feeling the filters never been changed

You'll find its clogged up solid. Should be done every year, every two years at most. Every one I've ever seen where the heater only works on speed 4 has had a blown thermal fuse on the resistor pack and a pollen filter blocked solid. The filters are less than a tenner. You'll need a set of torx bits to remove the trim under the windscreen to get access to it.

Thanks , if its only a thermal fuse thats failed i can solder a new one into it

Not on a Focus you won't.

Early cars had three cross-head screws, later just one.

Get the proper butyl seal from a dealer, and clean all the mating surfaces properly or it will leak for sure.

Chris

Eh? Err why?

because they are a ford and this model suffers from water leaks round the pollen filter (I thought it was early ones that had a major problem there)

Water leaks from the pollen filter cover into the passenger side are a well-documented Focus peculiarity. When you look at the design, it's hardly surprising.

Chris

Didn't think it was a Ford thing, just a Focus design fault.

The cover was modified around '02; the change seemed to be mainly to reduce the number of screws from three to one, and increase the number of breakable plastic clips that are part of the cover.

They certainly haven't made any improvement in the ability or otherwise to keep the rain out IME!

The above applies to all MK1 and MK2 cars; later are OK.

Fix Or Repair Daily :)

The old one were always the best... unlike Ford cars of course!

Chris

Thanks Chris , just repaired the thermal fuse , the pollen filter had never been changed was a solid mass of crap

yes its not very clever is it , like taking a few tiles off your roof
