FoggyF Posted February 4, 2018 Share Posted February 4, 2018 Picked up 2010 Ford KA for daughter and heating blows cold until you crank up the fan speed and their is a "pop" sound under the dash that suggests a plastic valve opens and allows hot air to enter the cabin. Suggests that this valve is sticking and just needs a blast of air to release this. This is a pain as it does need a few efforts at times to get this flap open - no good for my daughter when she is without a clear windscreen!! Can anyone confirm what this is and how it can be simply resolved. Quote Link to comment Share on other sites More sharing options...
Luke4efc Posted February 4, 2018 Share Posted February 4, 2018 I thought at first it could be the heater control valve, but I don't see how increasing the fan speed frees it off. Other thing I can think of is the blend door is getting stuck, and is probably an actuator failure. Couldn't tell you where they are located on a KA though.

FoggyF Posted February 5, 2018 Author Share Posted February 5, 2018 Thanks for your reply. Hopefully someone knows where the actuator failure is or it's off to the local ford dealer. Quote Link to comment Share on other sites More sharing options...
