Heater box removal - help

[dspeer]

I've been spending this Saturday under the dashboard of my 1970 280SEL w108, trying to gain access to heater and blower motor. Here is what I have removed so far:

- Upper dash cover
- glove box
- radio
- A/C unit
- all wood
- steering wheel
- drivers seat
- ducts to rear under seats
- ducts from heater to side of tunnel
- window switches
- center console

I am looking at the plastic box, and nothing is intuitive. I have so far removed the connection to a bracket in the upper center, one screw on upper left of plastic into bracket and two clips on right side of the plastic box.

Now I am sitting where normally the seat is, and I am scratching my head. I can't even figure out, what the part I am removing is. Does it go all the way up to the heater valve, is it just a front cover? The whole unit wiggles, but won't come loose.

Any help greatly appreciated!

I didn't see heater hoses on your list. Did you disconnect those? And the heater control panel/cables?

I forgot:

heater control panel is out.

heater hoses will go once I am ready to remove the heater.

When you said "The whole unit wiggles but won't come loose", it sounded like the next step would be to disconnect the heater hoses at the firewall.
