Default Cowl Area Drainage Problem

Just after washing my '95 Coupe yesterday, I noticed a fair amount water in the cowl area, just in front of where the windshield wipers come to rest. This doesn't happen in my '92 Coupe.

Is there a small drain that must be plugged somewhere?

Thanks in advance for your help/advice.

On my '93 there is definately one on the far driver's side, a rather large rubber tube. Can't say I know of where the pass. side drain is, but I'd think there has to be one since the cowl has a 'well' on that side also.

Remove the screws in the hood lip at the ends and clean out the dirt clogging the drainage area. It is easily clogged.

I've never found the passenger side one either, but on my 91 the drivers side drain was completely packed with fine dirt along almost its entire length. I found a continous plastic coil used for binding report papers to be the perfect item to clean out the drain. It could auger in without damaging the rubber drain tubing and then by pulling back the dirt came right out.

Thanks for the advice. I forgot to say that it's only the driver's side that is clogged.
