I have a 1.8 ford focus (2001).

The blower motor is only  working on #4, nothing on #1,#2 or #3. Some one mentioned that the resistor may have gone.

I removed the glove box and identified what I believe to be the resistor pack (blue in colour)  to the right of the blower fan .

I have removed this but can see no fault, is there any way to check this and am I on the right track.

Welcome to the BBA forum BigGrin

Generally speaking if the fan only works flat out & not on any of the resisted speeds the rheostat is FUBAR.My ford went the other way & would work on 1/2/3 but not 4 in which this case was the switch its self.
You could check the inputs at the rheostat if you so wished.

Thanks for the advice. I can now see from the pdf the reason it would work on #4 only.

I have just removed the fam motor and checked this out and it is free to turn, the bottom bearing area was a little rusty, I have since lubricated with a Teflon based lubricant. Tested fan operation okay.

I assume I just have to purchase a replacement rheostat assy from ford and plug `n` play to rectify problem.

Replace the resistor pack.

Ford also does a repair section for the loom if your plug is at all melted / damaged.

On a knife edge !
