I asked this question up in the "Big Chill" and didn't get an answer. Where is the condensate drain on a 77 Riviera? (BZ) It's draining into the interior on the right side of the tunnel upon acceleration. It's not coolant...it's water. I had it up in the air and can't see a rubber "burp" tube anywhere on the bottom of the HVAC box like the older GM's. Anyone know???
