W107 Rear Window Trouble

[ciro_ciampi]

Hi Fellow Merc Chums,

New to this, but like what I've seen so far and some of the tips have helped already...

I recently bought a 1974 450 SLC which had done 50 miles in approx 4 years, so the locks had seized,etc and she needed a good servicing before running her gently on a sunday....

I've got most things working now except for the rear quarter windows.. on pressing the switch the rear windows both come down a fifth of the distance under some strain, and then do not go any further, but need a helping hand getting back up...from a specialist or someone with know how approach...what should I do first...some people have mentioned the mechanism, or the motor, or the switches...!?!?!

One other problem is I have temperamental heaters...they are either on full time, or they don't come on at all...the switch doesn't really do anything...could this be the heater vacuum element ?

I'm not really mechanical minded, but the Haynes manual makes some sense although not always first time!

Your anticipated help is appreciated,

Chi :roll:

having a 114 1972 coupe - i would say first look at the seals - they often get clogged up and cause it to jam. Also check the mechanism, and re-lube it.

Not quite sure what you mean by the heater - do you mean its eithewr hot or cold with no warm setting - or do you mean that the fan is on full blast or nothing? or its stuck on hot all the time... If its the latter its almost certainly the heater control valve - or mono valve located on the bulkhead - theres two wires that connect to it (as in mechaical wires) - check the physical opewration - then if thats ok replace it. I think I have one spare from a (an?) SLC?

Hi,

thanks for the help with that, the car is currently in Cheddington, I have forwarded the suggestion to my Mechanic who is a Tring boy!

If I need the heater control valve I will let you know in the next few days and Ollie will be able to come over and pick it up from you...

Thanks again for the advice, and I will be in touch shortly...

Cheers
