Ac Quit Working On 300se
 

I have an 89 300se with 196k. Last late summer, I replaced the blower motor with a new unit and the ac worked great. It has worked great up until today at lunchtime. I turned the ac on and it didn't feel like the compressor was kicking in, but the blower is pushing plenty of air through all the vents, but it is extremely warm. The temperature here in TN has been about 80-85, so the temperature of the air coming through the vents is rather warm. I am at work right now and have not had a chance to check the fuse. Can anyone tell me where the fuse would be and is this a possible culprit? Thanks.
