SL/R129: Is it really possible to open the wiper, combination, N10/2 relay for an 92 SL, R129?




The reason why i wanted to take off the wiper, combination, N10/2 relay was to inspect all of the contact points for dirt and corrosion (No dirt or corroison at all on the relay or the 8 and 21 pin connector)
Another reason why i did take the relay off was to check if i could open the relay to check for bad soldering on the circuit boards and also broken electronic components.
Since all of the wires came off on the 21 pin connector for the relay i really did not care about the relay at all since i just focused on firgure out how to put the wires back on the correct pin assignement on the connector.
So i guess now is the time to inspect and open up the relay if it is possible

Some times perhaps a 2 or 3 times a year the right side park light in the headlight does not work and itt also have happended that the left side lights have been lit while tha car is standing parked.
And i know for a fact that the reason for this is inside the wiper, combination, N10/2 relay.
For me when looking at the relay it looks like there is now way you can open up the wiper, combination, N10/2 relay without braking apart the relay.
Is there any of my fellow member here on the forum that have opened up the relay and knows how to do this?
Is it really possible to open up this wiper, combination, N10/2 relay without braking it?

If i remember correctly cut the top off and push the bottom up through the top .These things are not meant to be taken apart.
If I were to do it again I would use a dremel tool and cut around the base and lift it off.




I guess you can use a dremel a cut thru the plastic cover on the relay so you get accessa and can check it for any bad soldrings or components that are damages and use "body epoxy" to glue the part you cut off back on.
The "body epoxy" i am talking about is used when the glue all kind of different materials together when they build cars so this epoxy will never come apart.
But i am pretty sure i read somewhere about somebody that had taken the relay apart without breaking it..
