hey all, just wondering if anyone has a copy of a wiring diagram for the multi-switch(wipers,cruise,signal) on a 2009 h3. i'm trying to see if its any different from the 2007 model diagram. thx.

 

ebay,,,i just ordered my 06-09 copy last night ,,,$15,,,ill look when i get it. you should grab one...15 bucks

 

It should be the exact same thing since the part #s form GM are the same.

What cha doing to it??

 

Just don't plan ti use it for switched ACC voltage. Won't work.

 

Just tryin to install one of those rain tracker automatic wiper deals. Their wiring instructions are wrong for the hummer h3. Its a **** off finding that out after being cramped up under the dash trying to do a proper job soldering all the connections. apparently there's a brown wire coming from the switch that's supposed to have 12v power but doesn't. is there any sort of switched +12v or ground wire that kicks in when the wipers are engaged?

 

this is my diagram for the 2007 model. does anyone have any insights to find a wire from the wiper switch thats a switched +12v or ground? lol

 

the switched 12v is from the relay that gets coil grounded by the bcm. the fuse on the relay output is the sw 12v

 

I just went through this two weeks a go. The "delayed off" business in the BCM buggers up using an existing switched circuit as a switched 12V source. The simplest way is to put an ATM size "Add-a-Fuse" pigtail in the Fuse #10 spare slot ( labeled "Accessories (SPO)") and run the wire, with appropriate fuse in the new holder, straight to your new accessory switch. If its for a high amp draw like lights, wire it from the battery but via a relay that's controlled by the fuse pigtail at Fuse #10 with a small fuse (like 1-3 A). Use the right wire gauge for the load and length.

(use at your own risk...yada yada.)

so what i'm gathering is my only decent option is using the wire directly off the wiper relay. i'm not looking for any old switched output, just one from the wiper switch that only kicks in when you turn it to intermittent wipe.
