Any body have an idea the possible problem area with back up ligh not coming on when shifting to reverse? The buls are good there is no fuse. Thanks for your help.

 

Check for corrosion in the socket and the wires.Or switch on the transmission is loose or broken.

1 bulb or both? only 1 you rule out the switch.and check power to the socket and corrision.

 

Thank you for response. Non of the lights comes on when I shift to reverse. checked the bulbs and wires and they are good, no crosion. I guessed the swith also bur I can not find the swith. I opened the middle shift comportment and the only switch I noted there is the RP lock valve. If you know where the switch is I appreciate telling me.

Thanks

 

Do you have the manual?If both are out the switch may be part of the nss or a seperate switch on the trans itself down by the linkage.I would start out now at the fuse box,in the 99 I have it lists fuse #3 as reverse gear recognition 7.5amp brown.Pop up the rear seat and see if yours lists the same,usually there is a fuse card in a little holder down there.

I do not have the manual but have the wiring diagam for 98 E430 which pretty similar to E320. I checked the fus and mine is fuse #3 also and it is fine. I am pretty sure it is the switch but I do not knoe where it is. I also checked the transmision by the linkage and the only think there is clear hose that goe to instrument pannel and it is oily at the linkage.
