Took a corner yesterday, in true Porsche form, and got a bath from what I can only assume was the AC condensate in a full drain pan. Any thoughts on how best to clean the drain hose ?

 

I have not done it on my 997 but have done it on other vehicles. You need to located the top end of the hose and blow some gentle air thru it. You can also check on a hot day with the AC on and see if anything is coming out the bottom. If it is maybe it s a drain issue under the font hood. Ever clean out those?

 

No, you mean where the battery is ? Didn't think that would spill into the driver's side foot well and I checked carpet and there wasn't any sign that the water was collecting in the floor pan area over a period of time. Just the one instance of it spilling on my feet . Would be worth checking though. Where is the opening for that drain ?

 

there are three or four black holes on the bottom of that battery compartment area.
I usually pour a few cups of water thru them and watch it come straight out underneath the car. (after I make sure they are clear of any debris at the opening).
PS/ I think you are correct in thinking it s from the AC most likely.
