Does anyone happen to know where this relay is located on an early W123? I'm having trouble with my blower fan not coming on. I removed the blower yesterday, and since the motor is sealed, I simply sprayed it, through the two holes in the motor body/covering, with some contact cleaner and it started working. It worked for most of the day. It did finally fail to start. I'm going to take the motor apart, even though it isn't really designed for that, and replace the brushes. But before I do that I think it would be wise to check the relay.

Thanks!!
