There is no drain hose on these . The water condensate runs out the bottom of the heater box , straight out into the engine bay , low down on the bulkhead . If you look closely, you should see a black plastic spout just protruding out .

It could be a problem with the thermal lagging that insulates the ac pipes where they pass through the bulkhead from the engine bay . When the ac is on , the pipes “sweat “ and produce water condensation.

Sorry, I don't believe this tale. There would need to be a lot of condensation for a footwell to get wet enough to be noticeable. Usually this means a rainwater leak from somewhere round the screen or in the scuttle, or possibly a leaking heater matrix - in which case it would smell of coolant and the level would drop in the coolant reservoir. 'Only when I use the air-con' just sounds unlikely to me.

As I suggested earlier, look under the bonnet for blocked dainage, clear out any muck and check the pollen filter is not sopping wet.

Some of the advice is from the various Fiesta forums.

So, therefore a coolant pipe leak inside the car?

Google AC specialist your area postcode and go and see them.

They can add a dye to coolant and check.

But surely if a coolant pipe leaks, it won't leak water. And you would smell whatever it might leak ?

If the dampness as described in the footwell is moisture, it may be condensation caused by using the air-con. That could be from human breath, wet clothing and footwear, or water getting inside the car some other way. If the AC circuit has a cold exposed pipe near that footwell, that could collect condensation. Find the pipe and lag it ?

No-one's suggested it might be on re-circ. That would mean any condensation inside the car would just continue to build up,

I think the problem is condensate dripping from the ac pipes . Take a look up behind the dash , driver side, above clutch pedal . There are 2 ac pipes covered in insulation. These pipes terminate to a block on the bulkhead . There may be damage to the lagging . This problem is nothing to do with pollen filters or rain water entry from the under bonnet area .

Weird. i cannot think it can be condensation from the air con. How long do you use the air con on a daily journey? My advice is to stop using the air con you do not need it this weather and see what happens when it rains. It is amazing how far a rain leak might travel before it dumps in a car

Looks like you need to pull the dash and heater/ac box out of the car to find what’s going on . Not a 10 minute job . Could be a fracture in the plastic casing .

Not too sure what part has been replaced , but the accumulator is in the front wing , behind the headlight . Can’t see how this can cause excess water build up on the footwell .

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
