Here is a queer one!

I took out the heater blower resistor on my MGF as the low speed was not working. Sure enough I found that the low speed resistor was blown. I have ordered a new one.

Strange thing is that I now notice that with no resistor block fitted, I now have low speed, speed 3 and speed 4 all working. Only speed two now runs only at speed 1.

This can not be explained (not to my logic anyway) by reference to the wiring diagram.

Any theories out there?

With the resistor pack disconnected the fan can only run on position 4, full speed.

I cannot see, with the wiring diagram how the fan can be running on slower speeds if the pack is disconnected.

Have you disconnected the resistor pack completely or just removed that one resistor and put it back?
Without the pack connected there is no circuit for 1,2,3 and only 4 should work.
