1987 300D -- A/C Compressor not working

This is my first post here and i'm hoping to learn alot from all the knowledge here...This is what i have.No A/C Compressor working automatically.When i bought the car 2 weeks ago, i found that the A/C relay ws jumpered and the previous owner was using a relay for a gasser E300.Replaced with proper relay and still does not work.With the old relay in, the compressor works fine and cools very well, but it runs all the time.The auto function of the Climate Control Panel works as advertised with the old relay in and jumpered.These are the items i've replaced.New Climate control panel,new relay,Low Pressure switch and i checked the Ohm values for the 3 sensors.I also checked the fren charge and it was good.What am i missing here? Thanks for your help.

what kind of climate control panel did you install? I assume you are talking about the ACC right?
I need an SDL !

A/C Climate Control is the A/C Climate Control Panel....How is everything in Atlanta?..I'm originally from Carrollton.A/C works great with the old relay thats jumpered.But a brand new relay thats the OEM won't kick the compressor...Got any thoughts?
