The cigar lighter on my car (95 E320) doesn't work.

With the ashtray removed there are two screws in back of unit.

I removed these. Many posts on this forum say the ashtray unit should then pull out.

Mine doesn't it...and I have applied a fair amount of pulling pressure.

Seems that it should pull out easily.

Any ideas as to what I'm doing wrong (or not doing)?

Thanks.
