Hey guys - got a problem on my '85 GSL. The ventilation system seems like it's clogged somewhere. When I have the blower on recirculate, air flows through the cabin vents. But when I turn off recirculate, the air stops flowing (but the fan blower still makes noise). Any ideas what could be wrong? If it makes a difference, the AC has been removed... Thanks

 

Fixed it. Pulled the glove box and half the dash, then took off the hood vent that covers the windshield wipers, and guess what it was. The guy I bought the car from had duct-taped the outside air intake. Go figure. Ripped out the tape and now air flows fine.
