Okay, you guys helped me with the replacement of my Blower motor, now something a bit more challenging.

88 300E. My cruise control has never worked since I bought the car 10 years ago. Did all 300E's come with Cruise Control? I have the Cruise Control arm control on the steering column so I assume it has cruise. Also, the rear power windows and the cigarette lighter have never worked either. Are all these things connected in some way? I have of course verified all fuses. What's up? Where do I start?

Bonus question. Is there supposed to be a back light for the shift indicator on the console? The power seat buttons light up at night, but not the shift indicator.

1.- Cruise Control Amplifier, behind the driver's side kickpanel. I have not heard of a W124 that have not had problems with it. (Do a search)

2.- Yes, there is supposed to be light on the shifter panel.

I believe all North American W124's came with cruise control, but the European cars weren't as "fully loaded."

At this age, don't just verify the fuses, replace them. Those ceramic units are very deceptive.

The shifter console is lit by a bulb under the shifter console.

The rear windows not working are probably a result of broken wires in the rubber elbow between the door and body pillar. Apparently typical for this vintage, I've had to do the fix for my hatch & left rear door. It isn't hard, just diddly and time consuming (set aside a full afternoon). You need to carefully pull the elbow and find the break (should be pretty obvious if it has parted, but not if the insulation is still intact). I found it was helpful to remove the inner door skin and solder the splice on either end of the elbow, I used stranded zip cord (12 gauge I think).
