Phew! Hot Ka!
We have a 2005 Ka collection and it is constantly putting hot air into the cabin as the engine warms- with temperature set to cold.
Both hoses to and from heater valve get very hot. I got a heater valve off ebay - didn't make a difference. I got a replacement facia - no change. I then got a heater valve from ford- still no difference ( I thought it was working though as it felt like it gave cold air for a minute or two. Then back to red hot!) I found another control unit so tried that- no change. Fuses are ok. Today I disconnected the multiplug and connected it to both valves in turn, set the temp in cabin to mid position so should be pulsing?? ( engine running) No movement whatsoever . I tried the test with all 3 facia's and the swapped the valves. No movement. I have heard there is a resister near where the passenger right foot would be. Is this just for the blowers or does it impact the heating in some way?? I have run out of ideas Can anyone suggest anything to try next. thanks |
The resistor is just for the fan speed, it doesn't control temperature. I would say it is probably a wiring problem, I guess these work on a stepper motor type setup, so I would be checking for change in voltage output at the plug when you turn the dial.

thanks ,I forgot to say that I have had a meter on the plug contacts Across the pins of plug measured 0v live to battery measured 13v ish the pulsing one measured between 0-0.3v depending where the temp dial was. (to battery) |
