Default Re: No power to top down or spoiler buttons

THAT is how you search here!

Unfortunately I still haven't found anything relating to no power to the console switches for top down and spoiler retract beyond checking fuses., seems something is breaking the power connection, just don't know what and where to go from the fuses. Again, I get no lights on either console switch.
You are making an incorrect assumption. The 'power' to the switches is provided by the top control module (top switch) and the Body control module (spoiler/wing switch). There is no power problem here.

Top operation is performed by the POwer Top Control Module (PTCM), that module interacts with the CLP/SSM and BCM to operate the top
Spoiler operation is all done by the Body Control Module (BCM) which gets information from the PTCM, CLP/SSM and Brake Controller to determine when it is permissible to move the top.

Chasing "power problems" is why dealers and garages cant fix these items. There is an interactive handshake between all of these items that determines when the spoiler and top can be operated.

Now, I said this is not a power problem, it CAN be, say if the BCM is not fully powered, (the BCM has four power sources, and has four "mini-modules" in it). But you can't determine this easily from measuring the bias voltage on the switches. YOu can have bias on the switch and still not have the BCM fully powered.

There are logical tests you can do:

1) Pop the top away from the windshield frame, does the top switch light come on? If you drive away, do you get the warning beep?
2) When you turn the D handle, do the windows go down anytime the engine is running?

If either answer is "no" you must STOP RIGHT THERE and fix things so you get both statements to be true. Do not go any farther until you accomplish that.
If both statements are true, I'f feel comfortable that the BCM is fully powered.

If the wing goes up at 60 or so, the brake controller is talking to the BCM, that's a pretty good sign.

Describe exactly how you "checked for a wet pump" (Locking pump not power top pump). Did you disconnectd EVERY connnector on the CLP/SSM? DId you look closely at the pins (both male and female) on every connector? Was there ANY dampness in the insulation package?

Have you taken the lid off the big box next to the battery and checked for rodent damage?
Consider pulling up the carpet on the passenger's side and looking for rodent damage in the wiring under the bulkhead that covers the audio amp/TCM.

IF you find any rodent damage, tow the car to a bad part of town, leave the keys in it, and let someone steal it. File an insurance claim and go find another Crossfire.
