Plugged drain hoses 1991 RX7 convertible
 

How do I unplug the rainwater drain hoses in my 1991 RX7 convertible? The drain hoses connect to the side pockets of the convertible top. I tried compressed air at the pockets but that plugged the hoses more. I should probably have tried the vacuum first. Now I'm trying to pull up the hoses from the wheel wells but they seem to be attached somewhere below. Does anyone know how to get the hoses out of the wheel well, or another way to unplug them? Thanks!
