Hello,

I just bought a '96 S320 and it's a great ride. The only problem is the windows, wipers and turn signals work intermittently. The issue has been happening since I got the car, but has gotten significantly worse.

I think it's just a bad universal relay but I just wanted to ask here first to see if anyone has experienced a similar issue.

Thanks,

Weygand

hey have checked your fuses to see if any of them are loose...

Phillip,

Thanks for the response. Yes, I checked all the fuses to ensure they were correctly seated.
Another thing I noticed was that this morning when I started the car the wipers/windows/TS didn't work. Then after driving about 30 minutes of driving around town they started working and have worked after me stopping and restarting the car.

Regards,
Weygand

hi , my name is simon ,I had the identical problems with my wiper and windows, did you by any chance find out what's wrong.let me know> thanks

Hey Simon...no luck so far. Now my problem is the driver's front window, passenger rear window, and sunroof no longer work I replaced the battery.

The SRS light still comes on randomly and then nothing will work. A couple minutes later and comes on again and the 2 still functioning windows work.

I wonder if I should buy a diagnostic tool

hi weygand,
I changed the mutil function board from MB, the SRS light still had problem, the car been working no problem for almost 2 months in dry weather, i notice this SRS light only had problem when it rain, I think the water get in somewhere and short the wiring. let me know if it is same for you.

simon

Hey Simon,

I think, based on the intermittent functionality that it's a short in the system.
I think I need to buy a diagnostic tool and see if I can get any codes

I'll let you know how I get on.

Regards,
