GUZZI SVT Posted October 13, 2014 Report Share Posted October 13, 2014 I have had this water leak coming from the HVAC box after going through one particular car wash but only when the strong lower quarter panel sprays in on. It is a brush type car wash so the rest of the car was in lower pressure. The first time this happen I took the windshield wiper area apart and cleaned the drains and checked for any reason the water would get into the HVAC intake. Is there any were down around the wheel well area that water could be blown into the HVAC air box area? I'm thinking about removing the inner wheel well to look around.

mjhpadi Posted October 13, 2014 Report Share Posted October 13, 2014 Just a thought but could it be the sunroof drain being blocked and leaking into the interior? Quote Link to comment Share on other sites More sharing options...

RichInMich Posted November 6, 2014 Report Share Posted November 6, 2014 Problem is your drain lines from your sunroof - had the same thing happen to me last year, dealer had it for 3 weeks due to parts shortage! You can't ignore it, it will never stop leaking unless you fix it. Quote Link to comment Share on other sites More sharing options...
LindenBruce Posted November 6, 2014 Report Share Posted November 6, 2014 Is there a way to run a pipe cleaner down the sunroof drain tubes to keep them clean? B. Quote Link to comment Share on other sites More sharing options...
mjhpadi Posted November 7, 2014 Report Share Posted November 7, 2014 I don't think a pipe cleaner is nearly long enough to do the job, I think the drain runs from the roof all the way to the bottom of the car, I know it did in our 99 Sable, which then the drain soaked the sound insulation, which caused rusting in the frame rails. Ford isn't the best on running drain lines. On my F-150 the AC condenser drain, dripped on the O2 sensor lines and caused it to short out.

LindenBruce Posted November 7, 2014 Report Share Posted November 7, 2014 Bummer. So what is a guy to do to help keep these things clean? A little compressed air every fall? B. Quote Link to comment Share on other sites More sharing options...
tss Posted November 8, 2014 Report Share Posted November 8, 2014 Compressed air works or running water in with a little pressure when its working properly. mjhpadi 1 Quote Link to comment Share on other sites More sharing options...
GUZZI SVT Posted November 12, 2014 Author Report Share Posted November 12, 2014 No, mine fills up the air box and it only happens at this one car wash where they have strong lower side blasts of water. Quote Link to comment Share on other sites More sharing options...
