[W124] 230CE '92 ABS and other queries

[Steve Nervig]

Hi Frank,

Sorry that didn't work, Frank.

I've shuffled my web site around a bit. New addy is <http:// 
web.mac.com/dakota/iWeb/Parts/Relay.html> for the relay, and I've now  
included the wire diagram pages from the ETM (Electrical  
Troubleshooting Manual) for the power windows and the sliding roof.  
Also the job for adjusting the roof.

I've also added a photo showing the N57 relay removed and my car,  
unlike yours, does not have that yellow relay beneath it, so I don't  
know what that is. Yours is not a convertible is it? Do you have  
heated seats? Could be front seat heater control N25/5.

Not sure what zip file you are talking about, unless it is from my  
Index page. The Index will be of no use to you unless you have the MB  
Service Library CDs.

I feel so much better now, since I gave up hope.
