NOTE:

At the start of production, A/C units were installed, where the left and right side of the radiator housing -D- and -E- were bolted together on the underside with the bolt -C-. From 07/2007 as a running change, A/C units are being installed, where both radiator housings -D- and -E- are bolted together with the bolt -F-.

From 07/2007 through 09/2007, the bolt -F- with the hex nut -G- was installed on the left radiator housing -D-. The left radiator housing -D- only has a hole and not an attaching point. To remove and install the bolt -F- and the hex nut -G- on this actuator version, the Temperature Regulator Door Motor -V68- or the Rear Temperature Door Motor -V137- must be removed. Refer to Temperature Regulator Door Motor -V68- /Rear Temperature Door Motor -V137-, REMOVING AND INSTALLING .

You can place a catch on the holes on the right side of the radiator housing -E- which will prevent the bolt -C- (and the bolt -F-) from falling in the hole after being loosened.

-- Carefully disconnect the connector rod -A- (so the lever does not get damaged) from the lever on the defrost door -B-.
