Well since posting the problem with my ford ka heater blower not working, today I finally got around to looking at it.. I've now checked all I can think to check, please see the results below....
1. resistor pack replace as it had burnt out..
2. fuse replaced.
3. electrical tests completed with the following results - with ignition turned on.
a) fuse ok power going to it
I've checked all four wires going into new resistor pack - NO power in all wires even when the switch is turned to all 4 positions.
c) then checked the switch (connector plug that fits into the fan switch) - no power in all 5 wires
d) checked the wire going to the fan motor - this has power
Can someone help me out as I don't understand why theres no power going to the switch and/or resitior pack (which I guess is on the same circuit. There is a big black orange wire going to the switch - this I think is the feed, whihc is dead. So where does the other end of this wire go to? Is there anything else I should be checking ? I hope theres a bright man out there can help me.... ?
