2007 MB GL450 Rear tailgate problem: GL 450 Rear tailgate
GL 450 Rear tailgate problem: Tailgate latch would not unlock when opening intermittently (when switch is activated latch does not unlock and hydraulics time out after a few seconds). Installed new latch and it still will not unlatch intermittenly. I have figured out that it seems to work better when the ambient temp is below 60F. If it sits in the hot sun it will not work and in the morning it works ok. I removed the Rear SAM module and removed the board from the plastic housing. Everything looks great (no signs of corrosion anywhere). There are 8 wires that run from the rear sam directly to the door latch. With the connector disconnected from the latch I Get 12V constant at pin 5 (red/wht) all other pins have ground signal present. I checked all of the pins for continuity between latch connector and SAM connector and all have less than 1 ohm. I also checked all pins except 5(12V) for continuity to ground between latch connector and ground with SAM connector disconnected and they are open. Using Autel MS906 the only codes present in rear SAM are 90E0 & 90DE - Obstruction sensors of the left and right Vent window has short to ground. These are hard codes which will not erase and are preventing the rear vent windows from operating as well. I'm thinking that I need to replace the rear SAM but am not sure. I would like to know what the function of the 8 wires to the latch are to be sure. Cannot find this info anywhere. … read more
