So I decided I want to do a complete overhaul over heater and a/c system...basically new everything. I'm trying to removal the whole housing from behind the dash. I've got this far:

I've removed the mounting for the housing located near the ashtray, as well as the four nuts found behind the blower motor cover on the engine side of the firewall. The housing still won't come out though (heater is drained and disconnected, as well the evaporator hoses). What else do I need to do? Does the blower motor need to come out? Help will be much appreciated...I'm running out of patience with this project!
