If 22 C (71 F) is always displayed after
switching on the ignition regardless of the last
setting, check voltage supply to E87 (terminal

E87 readout can be switched over from C to
F and vice versa by pressing the "temperature
+" and "recirculating air" buttons
simultaneously.
If E87 remains in operation after switching off
the ignition, test cable connection to E87
connector -D- contact -1- for short circuit to
positive (connection for auxiliary heater
operation) using wiring diagram.

hooked in or the motor can not be installed, connect motor to the
wiring harness, switch on ignition and place lever in appropriate
position by activating the button for air distribution on A/C control head
-E87-.
