89 560SEC AC Relay
Would it be possible for the compressor not to even kick on if the AC Relay is not working properly?

Strange sound at 1800 RPM while accelerating in 91 350SD
I just changed both fuel filters and the oil on my 350SD and on my test drive the car made a strange noise or vibration at 1800 rpm. It almost seems like a cavitation. Motor mounts are good....I did a diesel purge 3000 miles ago....and it's normal and smooth at all other speeds. It has a newer non-rod bending 603. New nozzles needed??

1987 300 sdl - odd starting problem
i am having odd start up/running syptoms. car starts and runs perfect when cold. after warm up, requires 2-3 starting attempts. intermittently will not take fuel after warm start (especially if i continue cranking on first attempt until firing - usually no more than 10 seconds). fuel filters have been changed, diesel purge performed (actually looked pretty clean). car has 241,000 miles and looks to have been pretty well maintained. timing chain is tight.

Poor MPG on 86 300 SDL
Since buying the car in 2004 I've always gotten 24-28 MPG city/highway/air on/air off. She's always be a quick start after I replaced the glow plugs in 2004. She charges down the highway as smooth as silk. A great traveling car.
The car sat idle last year while I was overseas. Since getting back home MPG has dropped to 10. No kidding, 10 MPG. I have changed all filters; air/ both fuel and oil. The car starts right up, idles nice, no smoke, no sputtering or hesitation while running or starting.
I've checked and replaced bad vacuum connections in the engine compartment. I have added diesel fuel additives in the tank, with no positive effect.
I've ordered the purge kit and will try that when it arrives.

Power Seats Not Working 0n '86 560 SEC
fuses checked-power coming to seat control module. 12v applied to seat motors-run fine. ohmmeter check of wires from door-mounted seat switch to control module-all fine. This leaves seat control module- disassembled and re-soldered all connections-seats still not functioning. What am I missing?
Thanks, John

w126 rear center console vent help please
My '82 w126 300sd center console rear vent (the one that exits out the back of the center console facing rear seat passengers) has been stuck open and when I pulled vent, I discovered why. Upon reinstalling, I have no vent function and it seems cable is now disconnected on the other end (front of car) the question is, where is the other end and where/how do I access? Thanks Kent!

1986 300SDL Loss of power after injector cleaning
After running WVO (2 tank mercedessource system) for 15,000 miles, i decided to pull out my injectors (monarch nozzles) clean them and bench test them. They all pop between 1850-1950 psi. I also, changed the copper washers and o rings on my injection pump and reemed/replaced glow plugs and glow plug relay.
