Autodata Technical Issue 24 - Water ingress on 2010 Ford C-Max

29 March 2019

Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This month a Ford C-Max is getting wet front carpets, creating window condensation.

Q. We are experiencing a problem identifying a water ingress on a 2010 Ford C-Max.

The front carpets are getting wet resulting in condensation on the windows. We have carried out exhaustive tests but can’t see how the water is getting in. Can you help?

A. We are aware of this problem which is caused by water entering the vehicle via the lower bodywork joint at the A-post (Fig 1.1). Remove the side trim panels in the RH and LH footwells. Using a suitable extraction tool remove any residual water from the A-post (Fig 1.2).


Seal the lower bodywork joint at the A-post with a proprietary body sealant. When the sealant has dried, paint the sealant to match vehicle body colour. Ensure the carpets are thoroughly dried out.
