Not familiar with the CQ climate control, but if you have a little vent
grille in the dash and electronic CC, there's probably an aspirator fan
sucking cabin air past a sensor that helps the CC decide to heat or cool
the cabin.  My aspirator fan in my '91 200q20v developed a shriek a year or
so ago that disappeared after I stuck one of those spray lube straws way
down the grille and sprayed some lube that included teflon.

Brake noise could be some crud stuck between the rotor and brake pad.
