'87 190E 2.3 A/C Compressor Relay...where is it?

[nhdoc]

Hi,

I'm trying to run down a condition where the a/c compressor won't engage. The low pressure switch is OK as is the fuse #2.

Is there a relay that controls the compressor clutch on the '87 W201. If so, could someone tell me where it is located please? I suppose I could always jumper 12V to the compressor clutch directly to test it but wanted to check the relay too.

Thanks.
