Transit Mk5 '98 Duetto Heater Blower resistor

It's a while since I last looked at one, but I'm pretty sure it can be accessed under the dash, on the central side of the passenger footwell.

Be warned - although the resistor is the most likely candidate, I had a similar issue on my Mk5 and I removed and tested the resistor which was fine. The fault was in the switch. But try the resistor first as the switch is (from memory) very expensive!

I should have said - on mine there were 4 speeds - 1, 2, 3 and full speed. If that's true of yours then it's unlikely to be the resistor at fault. However, if 3 is full speed on yours, the resistor is certainly a candidate.

IIRC it was one of the changes that they made very late in the life of the Mk5. A bit of a pointless "feature" to add an extra speed - I suspect it was only done so that they could use the same switch as they used in other Ford cars of the period!

Same here - last time I worked on one was probably 10 years ago - but I'm 100% sure that the one on my Mk5 was under the dash! Ah well, glad you found it.

Ooops - sorry about that... I should probably do the right thing and offer to come and help put the dash back together, but from here to Honiton is a bit of a trek!
