I have lost power to the tail gate wiper, tail gate lic. plate light, and tail gate lock. Any one know what it might be??

 

probably the harness in the rear liftagate. the same thing happens to the e class sedan. the harness breaks at the trunk lid hinge. and needs to be repaired. i honestly never did a repair on a wagon so i dont have the details for you on the repair but i wouldguess the harness/ wires are broken.

 

Thanks I will check this out today. Do you know if there is a relay that would be working these 3 things? I did check all the fuses. Thanks again

 

I had the same thing happen on an SL. Before making the splice, place a piece of plastic or rubber tubing on the wire and slide it back over the connection when complete. Mine also took out the highlight on the trunk lid.

 

I took the talgate apart and did not fine any broke or shorting out wires. However every wire in the taigate all went to a black box with the number 029 545 60 32 (00). everthing writen on it is in German so I do not know what it is. I checked att the fuses and did not fine any that were bad. How do I check if the box to see if it is bad and is it getting power?????

 

the tail gate doesnt usually have to come apart. there should be a rubber hose at the top of the hinge of the lift gate. the wires run inside the hose.

 

Thank you
I had checked both of the black boots that are on both sides of the gate. I opened both of them and did not find any wire problem. That is why I took off the gate inside cover and found the black box. I can seam to find what this box is and if it is getting power.

 

After checking for broken wires in the hinge boot and not finding any broken wires, I replaced the Tail gate controller Part # 029 454 60 32 and that fixed the problem. Now everything on the tail gate works again.
Thank you all for your help.
