My '89 Spider's passenger footwell fills up with water, sometimes, after a heavy rain or a vigorous washing. I've noticed 2 peculiar things when this happens:

1. The outside of the AC housing under the dash is all wet.

2. The Coco Mat has a reddish tint to it.

I recharged my AC a few years ago and included a Freeze 12 leak indicator dye, which I believe is the cause of the red.

There's just so much stuff jammed under the passenger side dash of the AC-equipped car that I don't know where to begin to look. I'm assuming that the water is coming in through the vent near the windshield, which is why it's only wet sometimes (depending on the direction of the rain/hose spray).

I've checked the drain hose for the AC and it's nice and clear - a blocked AC drain wouldn't explain why the outside of the housing is wet.

Any ideas to save me the painful process of getting up under the dash without a plan will be greatly appreciated.

Thanks.
