AC Blower - Wont Blow

[marytrue]

Hello. I've been to this site several times but as of today, I'm a brand new member. I sure hope someone can please help me get cool here in MS. I own a 95 C280 and I'm lovin it, but it's so hot down here and I can't get my AC to work. The blower won't engage, the compressor and fans won't come on. I replaced the control module; however, the mech said it has two hot wires and he couldn't determine what he needed to do to ground it? He did a temp ground and the blower came on, the compressor kicked on, cold, cold air blew out on the passenger side (only). However, he couldn't get the AC to work through the console panel buttons without the temp ground (so he had to disconnect the module because the AC would not shut off by itself). Is this making any sense to anybody? What do you think the problem could be? Is there a fix for me here in MS?
