Hi all,
Trouble-shooting my 'Birds inability to raise or lower the convertible top. I get zero pump/motor noise in either direction and zero voltage at the UP/DOWN relays, swapped the relays, no difference). I seem to have narrowed it down to the actual Raise/Lower switch but am looking for some insight from anyone that has had this issue in the past.
I have 2 different service manual sets, and both indicate the connector (C2138) is a 6-pin connector. Mine however is an 8-pin connector with 1 pin unequipped in the actual switch. I've verified the pins the associated wires go to and assuming the wiring color code is still correct I have the mapping to this 8-pin connector. Pins 1 & 4 indeed are 12v and Gnd as per the wiring color coding, so seems like the rest of the color coding might be correct.
My issue is that pin 3 (common) should not be connected to either pin 2 (lower) or pin 5 (raise) when resting. My switch has 2 & 5 shorted unless I am pressing the Raise button, which results in 2 & 5 being open, and 3 & 5 now being shorted.
Two questions then:
1) Have others seen this 8-pin configuration and is the above consistent with the color coding ?
2) Is it possible that pin 2 & 5 being shorted has somehow messed up the pump/motor with it being constantly in the lower setting (assuming this is indeed what happened). Never heard the pump/motor constantly running so seems this isn't the case, but that causes me to question if the color coding is indeed correct or not.
I've found a replacement panel with the switch and have ordered it, but am looking for any additional insights while waiting for it to get here.
Thanks everyone for the assist.

For reference, here is the connector wiring as I have determined it. Actual connector numbering (per me), lower right #1, lower left #4, upper right #5, upper left #8
Looking into the connector, using
-Pin 1 (wiring diagram), Pin 1 (actual connector) is on the lower right (Black/Green): Ground
-Pin 2 (wiring diagram), Pin 3 (actual connector), (White/Red): Lower Top
