'96 C280 A/C and CEL
 

Last week Check Engine Light came on and at the same time the A/C stopped working. Compressor is not coming on. I have not had the chance to get the code yet, but my question is about the relay.
On 124 bodies the relay is behind the fuse boxes.
Is there a relay on this car, and if so where is it, or which positon is it. I do not have the shop manual fo rthis car.
Anything else I can check?
Any help is appreciated.
