Hi,
I have 1999 SL320 which i realy enjoy.
For last few months, on and off problem with wiper system specially when it is raining!

I would suggest that you pull out the multi function N10 relay and spray some none drying switch cleaner on all the pins. If this does not solve it the other known problem on a 1999 129 is the ignition switch failing

You could check this by turning on the radio,, if it crackles or goes off when the wipers are on then possibly more the switch

It could be a dry joint inside the N10 relay

Thank for suggestion. I do not know how to pull out N10 relay so i will take to garage. To inquire for parts, should i ask ignitian switch for 1999 SL? any idea how much it can be?
Thanks

It has to be worked out if relay or switch, a competent man should know where to check for the missing voltage when things stop.

We had one a while back where the N10 had been getting so hot the sockets in the fusebox were melted.

In about 1997 the wiring was changed passing more current through the switch, rather than the fusebox
