Arthur Dalton PMed me with just the right info. He had me jump the fan at the low pressure switch. The fans did not turn on but I did hear a click from Fuse box. From here he guided me to the relay which is behind (towards firewall) the regular fuses. All I needed was the hood straight up and a phillips head screwdrivers to access it. Six screws is all it took.

Once the panel comes off there are two relays, each with blade style fuses. Just as Arthur had supposed, the original fuse was 15 amp and was blown. The relay is blue. According to him Mercedes changed it to 25 amp, but he uses 20 amp with success. I got a multi fuse pack and put in a 20 and voile! Cranked the car up with A/C on and fans turned on low immediately. Car now stays between 80 and 100. Even when idling!

Thanks so much Arthur, Hopefully this helps someone else!
