2003 CLK with a power seat problem I need elec Diagram
 

I just picked up a 2003 CLK320 Cabriolet at a very good price and the only issue is the forward and backward movement of the driver's power seat is not working, I have not had a chance to trouble shoot it, I am just guessing either the switch or the motor, cant be much else. Does anyone have any tips to troubleshoot? Mainly I am looking for the wiring diagram for the electric seat switch and motors so I can apply power to the motor to check it.
Thanks

The fore/aft seat motor is beneath the seat cushion. If you unbolt the seat and tip it back, you'll see it next to the seat control unit. The font and rear seat cushion up and down motors, as well as the fore aft motor, all have the same color wires going to them. The black wires are the ones that get power/ground, depending on the direction of travel. The other wires are for the position sensors.

Thanks.
I will pull the seat this afternoon to test the fore and aft motor to see if it is still good. Hopefully it is just a simple issue, the motor seems to be hard to find used and the dealer cost is fairly high.

I found the part on the EPC 208 820 08 42 Looks like it was used from 98 to 2003 so that might make it easier to find salvage if it is bad.

Problem solved the easy way...logic...did a search and noticed that each motor has a seperate fuse, hidden in the trunk area, small in the Cabriolet...
Sure enough the fuse was bad, hope it doesnt start blowing a lot indicating a motor going bad, but for now the seat works fine and I got the used car dealer to drop his price even more for a burned out fuse, ha, chalk one up for the buyer for once!

I have a 2006 clk with the optional "comfort" seat, with all the pneumatic adjustments. All the standard power operations work fine but none of the switch (right side of the seat)to the air control makes a sound or inflate.Any suggestions how to go about it? I checked under,and could not find a pump or compressor .
Thanks
