Where are the grounding points for these codes? I have the printout of where all 13 grounding points are but because I have limited time to work on my car I'm hoping I can pin point the ones I need to check.
I received these codes one before about a month or two ago. They go away for that long when I clear them.

C1725 RR Shock Absorber Solenoid (Short to Voltage) -This one might be a bad shock.

B0432 Rear Defogger Relay Circuit
B0332 Outside Air Temp Sensor Short to GND
B0337 Inside Air Temp Sensor Short to GND
B0361 Left Actuator Feedback Short to GND
B0365 Right Actuator Feedback Short to GND
 
If I may, I think the problem is not where the ground points are, but where is a common point for those circuits that is shorting to ground. I think you have a wire that has chafed the insulation off of it and is contacting a ground point somewhere (probably under the dashboard).

First, disconnect the battery while you are doing the tests.

If you take an Ohmmeter and probe the wiring harness at a point(take for example the interior temp sensor) and find that it is making a zero Ohm contact with respect to ground, that wire is grounded. Probably the best way to find where it is grounded is to look at the wiring diagram and see where all of the problems come together on one circuit. Then identify where those wire are physically, and start moving the harness around while watching the meter.
If the zero Ohm contact disappears while moving a wire, start looking for points that are rubbing on a metal part that is connected to ground.
