Help please, my ford bantam heater just starts while using the ac. The aircon is pouring water in to the car on the pasanger side underneath the dashboard!. And if n switch off the car it starts overheating! So I think that the cooling fan is also not working right! What can the problem be?
The ac only drips water when its on
The A/C has an evaporator in the cabin, under the dashboard that will collect moisture when it is operating and there is a hose to drain it outside the car. That hose has apparently come unattached, and the water, which is normal and expected, is dropping in the car instead of going out the drain hose. Now, when you 'switch off the car it starts overheating?" How do you know if it's overheating, if it's off the gauges will not be on..maybe when you turn it off, it just goes to the hot end of the gauge by default and is not overheating at all. A car can not overheat if it's not running. Can you hear the fan run? If you mean the fan comes on after you turn the car off for a minute or 2, that is normal and also does not mean it's overheating.
Also have you checked the coolant level in the external reservoir? It should be less than half full cold. maybe 1/4 even. Do not pop a hot radiator cap..but when the engine is cold, then check that too, it should be full to the top and either green or reddish/brown, that is something I very much dislike when they came out with that color coolant, it's difficult to tell if it is the right color or rusty water
The heat gauge is normal while driving but when I stop and switch off for n few minutes and switch on again the gauge goes up into the red. So then the fan comes on and the gauge goes down! The coolant is on level an the car is runnig cool its only when I've driven for a while and stops! The ac drain pipe makes sense! Thanks
If it cools down immediately after starting it back up, I wouldn't worry too much. I was confused about overheating after you shut it off, but now I understand.
I have the same problem of the heater coming on whether the AC is on or not, but not the other problems you mention. So far I still have to find an intelligent answer to the problem, but it seems common in the Bantam and Ikon.
My bakkie also had a problem with the A/C leaking water in the cab, the drain plug was blocked.
Check if your heater control switch is functioning properly, it's controlling the temperature by pulsing the supply to the heater valve. If you test for voltage on the two wires connected to the valve it will show 12volt in both cold and hot settings. Instead of me describing how to test please google "Ka heater switch testing" there's a video explaining the working and testing of the switch.
