clk cabin floods when it rains

[richard28]

My 99 clk floods under & behind the driver's when it rains. The windows have been adjusted ($200 for 2 hrs labor), but that didn't help. On my return visit to the dealer this week, the shop foreman suggested that twigs, leaves or other debris that landed on the windshield cowl might have clogged the air conditioning drains so that rainwater travels into the channels on the floor and accumulates. He said the only way to check was to remove the center console, etc. I thought these drains could be blown clear. What should I do? BTW, the car went out of warranty in Feb.
