Dear GM B-Body HVAC team...

F*ck you.



Seriously, that hidden screw at the firewall is a bag of dicks. Since none of the other solutions from my search worked and I didn't have other tools mentioned, I used a deep well 7/16" socket pressed over the screw head with my right index finger. I then used small vise grips to grab the socket and turn (little by little). Passenger seat not removed. But now that the bottom cover has been removed, I think it's rather obvious that my heater core is clogged.

It may be hard to see, but the first picture is of the hoses to the heater core in front of the alternator. The second is a side shot of the heater core itself (right hand side of core is to the firewall). Not much heat getting through that. Time to swap it out, I guess.
