mystery switch
Any ideas on what this rocker switch (just above electronic brakes) does? It doesn’t seem to turn anything on/off, (no lights or compressor/door lock, etc). SMB-W nor my mechanic have any ideas. So if any ideas – please let me know, thanks/BigDog

Re: mystery switch
It should be your hi idle switch. With van idling in park and parking brake set, turning this switch on pulls rpms up for battery charging.
When I bought my van used, it drove me nuts for days trying to figure out what that switch did.

Re: mystery switch
If it is the Hi Idle, the van nees to be in Park, with the parking brake engaged. Start the engine, then try the switch and see if the idle speed changes.
If not, the only way to be really sure is to start tracing where the wires go. No fun in a van, that's for sure.

I have the same switch in the same place. Mine turns the backup camera on when not in reverse.

Re: mystery switch
Mine engages the van's cloaking device. It helps me remain stealth in crowded areas.

Re: mystery switch
Another possibility.
I have a switch in that location that turns on and off the amplifier on the sound system. The A/V guys put it in (Not SMB) which might explain why SMB doesn't know what its for.

Re: mystery switch
it might also turn on hella backup lights if you have them but more than likely its the idle switch

Re: mystery switch
The A/V guys at SMB used it on mine to be used in conjunction with other switches to turn on the SAT TV.

Our 2008 does not have a high idle switch. We do have a switch down there that turns on the extreme air compressor.
